Amnirana parva sp. nov. differs from other West African Amnirana genetically, morphologically, and acoustically. The uncorrected pairwise-divergence in 16S ribosomal RNA between the new species and its closest congener, A. fonensis, is 5.8%. The new species can be distinguished from A. fonensis by several morphological traits in male specimens. SVL of male A. parva sp. nov. (41.9–50.4 mm) is smaller than in A. fonensis (48.7–65.3 mm). Area of humeral gland is smaller in A. parva sp. nov. (3.7–14.8 mm 2) than in A. fonensis (13.5–26.4 mm 2) as well. Males of A. occidentalis and A. galamensis reach larger SVL (67 and up to 80 mm, respectively; females of these species reach 96 and 86 mm, respectively), have differing color pattern and completely smooth dorsal skin (R̂del & Bangoura 2004; Channing & R̂del 2019). Most males of A. parva sp. nov. have dark spots on the dorsum. Breeding males of A. fonensis differ by a yellow dorsal coloration. The ranges of two Central African Amnirana species that are morphologically similar to A. parva sp. nov., A. albolabris (comprising various lineages, see Jongsma 2018) and A. asperrima (Perret, 1977), do not overlap with the new species. Nominotypical A. albolabris from Central Africa show a larger body size in males (Perret 1977 reports 44–57 mm SVL for A. albolabris from Cameroon). Amnirana asperrima can also be distinguished by both its larger adult body size (SVL of males: 46.7–60.1 mm) and the texture of its dorsal skin, which is densely covered with tiny spines. Other Central African Amnirana species show distinct morphological traits and cannot be confused with Amnirana parva sp. nov.: A. amnicola (Perret, 1977) adults are larger (SVL of males and females: 53–72 mm) and have a more pointed snout; and A. lepus (Andersson, 1903) adults are much larger (SVL: 70–100 mm), have finely granular skin, fully webbed toes, and much longer hind limbs. Last, the new species also differs from populations previously referred to A. longipes (Perret, 1960) that are much larger (SVL 77–87 mm) and have a more robust body and longer hind limbs. Although we follow Jongsma (2018) in recognizing A. longipes as a junior synonym of A. albolabris, we include it here in anticipation that this may be recognized as a valid taxon if one or several lineages of Central African A. albolabris are recognized as distinct species. Description of the holotype. Figs. 5–6; measurements in mm. Adult male with long and slender body, slightly dorsoventrally flattened; snout–vent length 42.9; snout acuminate with rounded tip in dorsal view, narrowly rounded in lateral view; head length 15.8, approximately 27% of SVL; head width 13.6; eye–snout distance 6.7; nostrils directed laterally; nostril closer to the snout (1.7) than to eye (4.7); eye diameter 6.1, slightly larger than tympanum diameter (5.2); interorbital distance 4.3; approximately one third of eye projecting above dorsal margin of head in lateral view; canthus rostralis distinct and sharply protruding; loreal region concave; anterocranial part of upper arm with large protruding gland (3.6 long, 2.0 wide, surface: 7.2 mm 2); long and slender fingers, tips broader than subarticular tubercles, forming discs, reaching 130–200% of finger width, inner metacarapal tubercle large and elongated, outer metacarpal tubercle smaller and more rounded; manual webbing absent; finger formula IIVariation. Measurements (in mm) of all individuals are summarized in Table 5. Overall, the male paratypes were similar to the holotype in external appearance and coloration. Male SVL ranged from 41.9–50.4 (mean ± sd: 45.9 ± 2.9, N= 13). The humeral gland area spanned between 3.7–14.8 mm 2 (9.4 ± 2.7 mm 2, N= 13). Female SVL ranged from 53.6–75.6 (63.9 ± 7.8, N= 10) thus markedly exceeding male SVL (Fig. 7). Seven of 13 showed slightly more extended (1-1), and a single male paratype showed slightly less extended webbing (2-2) of the fourth toe. In female paratypes seven of 10 individuals exhibited a webbing formula with slightly more extended webbing on toe IV(1-1). The dorsal skin was covered with small tubercles in all individuals, but females had fewer, smaller, and less spiny tubercles. In some individuals, the skin appeared almost smooth at first sight, but tiny granules were always present upon detailed inspection. The dorsolateral ridge was interrupted in the majority of specimens: females (six of 10) and males (nine of 13). Females showed a brighter brown dorsum and few to no dark spots (see Figs. 6b, 7b, 8e, g, 11c). On the dorsum of males, the ground color varied from chocolate-brown to dark brown and all males had at least some dark spots. The ventral coloration varied greatly among males. Among the paratypes, some had a plain white throat (e.g., ZMB 88549, 87112), similar to the holotype, whereas others exhibited dusty brown speckling covering almost the entire throat (e.g., ZMB 87113). The belly of all males were white to cream, and some individuals had irregular brown spots (e.g., ZMB 87110) that were densest near the legs, throat, or flanks, but were absent at the center of the venter. Females showed some color variation on the venter. In ZMB 87114, the belly and throat were white, whereas ZMB 79253 and ZMB 79197 had a cream-colored belly and a dusty brown speckled throat. Concerning life coloration (Figs. 8, 11), the dorsum exhibited various shades of brown, sometimes with darker spots (especially in males, most females without darker spots). The flanks in males were greenish yellow (Fig. 8f, h) to chocolate brown dorsally (Fig. 8b), usually turning lighter ventrally (but see Fig. 8a). The flanks in females were olive green, turning paler ventrally (Figs. 8c, e, g, 11c), and becoming almost cream-colored towards the belly (then often with some greenish or brownish mottling). The tympanum was brown in both sexes. Males had a narrow green line surrounding the eyes. In both sexes the iris was golden, sometimes with a reddish tinge, with the lower half of the iris being darker. The limbs and dorsum were a similar shade of brown in both sexes. The limbs sometimes were somewhat lighter, but with darker patterning. The number of conspicuous dark transverse bars on the hind limbs varied among individuals (e.g. compare Figs. 8b & 8h). The venter was beige or cream. Both sexes had a light cream or white upper lip, and rarely the anterior part of the lip was brownish (Fig. 8h). Juveniles showed a more contrasting pattern compared to adults. It consisted of a greenish brown dorsum with black spots and an almost black loreal region and flank. The ventral part of the flank and the belly were white with black dots. The juveniles had more conspicuous dark cross bands on the hind limbs and blackish dots on the forelegs; a bright white upper lip, and a bright red iris (uppermost part golden) (Fig. 11f). Acoustics. The advertisement call of Amnirana parva sp. nov. consists of a whiny-voiced croaking sound with ascending frequency modulation from 932 to 1092 Hz (mean ± sd: 1030 ± 86, N= 3). The sound consists of up to five harmonics of which the second-lowest is the dominant one in the first half, the lowest one in the second half (Fig. 4a). The call duration ranges from 0.26– 0.78 s (0.52 ± 0.26, N= 3). Dominant frequency at the beginning of the call ranges from 948–1034 Hz (1004 ± 49, N= 3). All call characteristics are summarized in Table 4. A call description by Schiøtz (1964c) from central Sierra Leone seems to refer to our new species. In that paper, Schiøtz describes three different sections of the call (such a clear distinction of sections was not detected by us). Call duration and complexity, however, seem to increase with the motivation of the frogs (MOR pers. obs.). Schiøtz (1964c) also mentions that these calls were different from those he recorded in Cameroon for A. albolabris, though he did not provide further details. Distribution. Confirmed A. parva sp. nov. records so far are known from western Sierra Leone to southerncentral Ghana, all within the belt of the (former) rainforest zone, bordering the southern humid Guinean savanna (Fig. 9). So far, no confirmed genetic records exist for Ivory Coast. However, morphologically we could assign frogs from the Taï National Park, the Azagny National Park, the Banco National Park, the Haute Dodo, Cavally and Tanoé forest reserves, as well as the Ivorian parts of Mount Nimba to the new species. Other formerly published records of A. albolabris (see literature cited below) from this country from habitats that include primary lowland evergreen and humid but semi-deciduous forest cannot be unambiguously assigned to either A parva sp. nov. or A. fonensis (see below). Life history. It is difficult in many cases to assign previous field observations and literature records to A. parva sp. nov. or A. fonensis. We summarize observations based on confirmed records (morphology and genetics of vouchers, and/or acoustics) as well as records, which originate from primary humid-evergreen rainforest. The latter decision was based on the results of the environmental niche modelling (see below). All observed and collected individuals of A. parva sp. nov. were encountered in closed primary or slightly degraded lowland rainforest, on the banks of or near to small to medium-sized streams (Fig. 10). In Banco National Park, southeastern Ivory Coast, the species was recorded in the forest, forest patches dominated by bamboos, and in man-made ponds of a fish-farm in a forest clearing (Fig. 11a, b).

Medium-sized, slender frog, SVL of males range from 48.7 to 65.3 (mean ± sd: 57.2 ± 5.2, N= 10); a female measured 68.0; head slightly longer than broad, approximately one third of SVL; snout acuminate with rounded tip in dorsal view, narrowly rounded in lateral view; tympanum diameter around 85% of eye diameter, in two type specimens (SMNS 11788 & 11790) tympanum slightly larger than eye; inter-orbital distance slightly smaller than eye diameter; nostril closer to snout than to eye; canthus rostralis distinct and rounded; loreal region concave; dorsolateral ridge broad and protruding, only two male individuals show slight discontinuities in the posterior third of the ridge; males with large humeral glands on anterocraniad part of upper arms; area of humeral gland spans between 13.5–26.4 mm 2 (20.5 ± 4.86, N= 10); fingers long and thin, without webbing; tips rounded, forming small discs; finger formula: II– d), dark spots on dorsum and bands on hind limbs visible but paler; limbs and yellowish brown; flanks yellow, lighter towards cream belly; lip and throat bright yellow; dorsolateral ridge yellow to reddish brown; tympanum of breeding males with yellow center bordered by pale brown ring; tympanum of females dark or reddish brown (Fig. 13e, f). Acoustics. The advertisement call of male A. fonensis consists of a whiny-voiced croaking sound with an ascending frequency modulation of 548–723 Hz (mean ± sd: 633 ± 87, N= 3). The sound comprises up to five harmonics of which the lowest is the dominant one (see Fig. 4b) and lasts 0.55– 0.92 s (0.7 ± 0.19, N = 3). All call characteristics are summarized in Table 4. Distribution. Amnirana fonensis was described from the Pic de Fon, Simandou Range, and from the Haut Niger National Park, both located in Guinea. Our new records add further localities, including the first records from eastern Sierra Leone, the Nimba Mountains in northern Liberia, and central Ivory Coast. However, we cannot at this point clarify which previous West African records of Amnirana albolabris refer to either A. fonensis or A. parva sp. nov. (but see below). Life history. The observed and collected individuals were found near forest streams. These forests were less humid than in confirmed A. parva sp. nov. records and comprise semi-deciduous and degraded forest fragments (Fig. 14d) surrounded by savanna. Amnirana fonensis males differ from breeding A. parva sp. nov. males, by a bright yellow breeding coloration. Similar yellow breeding color has been reported from many, unrelated frogs across the tropics. In West Africa such color change has been observed in Phrynobatrachus alleni Parker, 1936 (R̂del 2003; Kanga 2021), Sclerophrys maculata (Hallowell, 1854) (Hillers & R̂del 2007) and S. togoensis (Ahl, 1924) (R̂del & Bangoura 2004). Amnirana fonensis breeds in water bodies of different sizes but seems to prefer stagnant or slow-flowing water. In a savanna-like habitat (Foma), males called from inundated patches, well concealed between grasses and reeds. In degraded gallery forests at Wataférédou, males called while floating on the water surface (Fig. 14a), well concealed between roots of trees and shrubs, or between low vegetation at the water edge. One to two males initiated calling and many other males then joined the chorus. Amnirana fonensis called at night as well as during the day. For instance, between 20:35 GMT and 23:00 GMT, we encountered many calling males (N> 100); the peak of calling activity was between 20:40 GMT and 21:30 GMT. Likewise between 14:45 and 16:00 GMT, we observed numerous calling males (N> 70); the peak of calling activity was at 14:57 GMT. In Foma, females attached eggs to grasses emerging from flowing water. After a few hours these eggs became submerged. In Wataférédou, the eggs were deposited between roots of trees and shrubs in the forest streams. The dark brown and yellow eggs were deposited in large clumps (Fig. 14b, c). We counted 809, 1074, and 2017 eggs in three clutches. The egg diameter ranged from 0.9‒2.4 mm (mean ± sd: 2.1 ± 0.42 mm mm; N= 100). We observed aquatic heteropterans (family Nepidae) preying on the eggs. It is likely that the tadpoles described by Lamotte (1957) from the Simandou range, can actually be assigned to A. fonensis. At Wataférédou, where A. fonensis was breeding, the forest stream was regularly polluted by people washing laundry. The edges of this gallery forest were degraded by subsistence farming, and cattle, and cleared for charcoal production and fuelwood., Published as part of Griesbaum, Frederic, Jongsma, Gregory F.

Diagnosis. The species is referred to the genus Afrixalus for exhibiting the following characteristics: fingers and toes webbed; tips of fingers and toes enlarged to discs; eye large; pupil vertically elliptical; tympanum indistinct; vomer ridges and teeth absent; dorsal surfaces finely shagreened with minute pointed tubercles; outer metatarsal tubercle distinct; gular gland in males. It is readily distinguished from most other members of the genus by its small size (SVL in males 18.9–22.2 mm, in females 20.8–25.7 mm), being smaller than A. dorsalis (males 25–28 mm, females 26–30 mm), A. fornasini (males 30–38 mm, females 35–40 mm), A. fulvovittatus (males 23–27 mm, females 25–28 mm), A. lacteus (males 22–27 mm, females 25–29 mm), A. leucostictus (males 27–32 mm, females 25–36 mm), A. manengubensis (males to 32 mm), A. nigeriensis (males 28–34 mm, females 32–35 mm), A. osorioi (males 27–31, females 32–35 mm), A. paradorsalis (males 28–34 mm, females 32–35 mm), A. septentrionalis (males 19–21 mm), A. vittiger (males 22–25 mm, females 25–28 mm), and A. wittei (males 27–30 mm, females 29–33 mm); and larger size than A. delicatus (males 15–19 mm, females 17–22 mm) and A. stuhlmanni (males 15–21 mm, females 17–25 mm). Its differs in dorsal coloration and pattern from all species with longitudinal stripes or bands on a yellowish-brown background (A. brachycnemis, A. crotalus, A. delicatus, A. dorsalis, A. enseticola, A. fornasini, A. fulvovittatus, A. knysnae, A. morerei, A. orophilus, A. quadrivittatus, A. schneideri, A. spinifrons, A. stuhlmanni, A. upembae, A. septentrionalis, A. vittiger, and A. wittei); species showing a conspicuous large dark dorsal blotch on a uniform background on anterior dorsum in combination with large blotches on both sides of the hip (A. leucostictus, A. manengubensis, A. osorioi, A. paradorsalis, and A. schneideri) or with longitudinal lateral dark bands (A. equatorialis and A. nigeriensis); species with a uniformly colored dorsum without conspicuous pattern except a dark dorsolateral stripe (A. aureus, A. clarkei, A. delicatus, A. fornasini, A. lacteus, A. leucostictus [dorsum with small white tubercles], A. uluguruensis, and A. weidholzi [might have a black vertebral line and dark brown flanks]); and from all remaining species having either dark stripes running from tip of snout to back, crossing each other and continuing as dorsolateral stripes (A. vibekensis, also males without asperities); anterior part of dorsum yellowish with brown pattern, posterior part of dorsum translucent (A. laevis, also males without asperities); posterior part of dorsum and dorsal sides of limbs semi-translucent with dense small dark white-edged speckles (A. dorsimaculatus); and dark blotches and transverse marks with white speckles (A. sylvaticus). It is most similar to A. phantasma sp. nov. but differs from this species in being smaller (Table 1) and showing an overall darker coloration and more contrasting dorsal pattern that is obvious even in preserved specimens (Figs. 7–8, 12). It is readily distinguished from A. phantasma sp. nov. by the more extensive hand and toe webbing (Fig. 8E–F). Description of holotype. Measurements of the holotype are provided in Table 2. Body very slender, widest at temporal region, slightly tapering to groin (Fig. 8D–F); head small (HL/SVL 0.31, HW/SVL 0.31), about as long as wide (HW/HL 0.99); snout relatively long, rounded in dorsal view and in lateral profile, slightly wider than long; canthus rostralis hardly discernible, slightly concave between eye and nostril in dorsal view; loreal region oblique; nostrils rounded, directed anterolaterally and slightly dorsally; situated much closer to tip of snout and to eye, separated from each other by distance about equal to distance between eye and nostril (IN/EN 1.02); eye directed anterolaterally, strongly protruding, very large (ED/HL 0.39), its diameter shorter than snout (ED/SL 0.90); interorbital distance much wider than upper eyelid (IO/EW 1.61) and wider than internarial distance (IO/IN 1.31); tympanum covered by skin, not visible externally; upper jaw with dentition; teeth on premaxilla larger than teeth on maxilla; choanae small, located far anterolaterally at margins of roof of mouth, its anterior edge covered by maxillary bone, therefore appearing semicircular in ventral view; vomer ridges and teeth absent; tongue heartshaped, longer than broad, bilobed for about one-fourth of its length, free distally for about two-thirds its length; densely covered with minute papillae; median lingual process absent. Dorsal surfaces of head, trunk, and limbs and lateral surfaces of trunk finely shagreened; tiny pointed, widely scattered tubercles on dorsum, more numerous posteriorly than anteriorly; supratympanic fold absent; few tubercles at rear end of mandible without pointed tips; ventral side of head smooth; vocal sac present; gular gland of vocal sac smooth, large and wide, covering about 70 percent of throat width (Fig. 8E); chest smooth, abdomen weakly areolate; ventral side of limbs smooth; short transverse fold above vent. Forelimbs slender; hand large (HaL/SVL 0.28); tips of fingers enlarged into large disks, each with circummarginal groove; relative length of fingers: I I 2-/2 II 2-/3- III 2.25/2 IV; thenar tubercle oval, small and very low, about one-fourth length of metacarpal of Finger I; inner palmar tubercle and outer palmar tubercle very low, small, rounded, almost indiscernible. Hind limbs slender, moderately long; heel reaching to level of eye when legs adpressed forwardly to body; crus moderately long (TibL/SVL 0.44), slightly shorter than thigh; heels not touching each other when knees flexed and thighs held perpendicularly to median plane; foot subequal in length to crus (FoL/TibL 0.94); relative length of toes: I I 1.5/2+ II 1+/2+ III 1+/2+ IV 2/1+ V (Fig. 8E); inner metatarsal tubercle moderately prominent, elongated, about half length of metatarsus of Toe I; outer metatarsal tubercle small, rounded. Coloration in life. During night, skin on dorsal side of head, trunk, forelimbs, crus and tarsus light brown with more or less regular, locally more densely clustered dark brown speckling; distinct dark brown transverse stripe between upper eyelids, another less distinct one in scapula region, and another narrow one at level of anterior end of pelvis; dorsal skin of thigh largely unpigmented with only a broad stripe of widely scattered brown pigmentation; distinct dark brown band along canthus, continuing behind eye on both sides of trunk to level of pelvis; tubercles below eye and in tympanic region at rear end of jaw white; dark brown stripe running diagonally on middle of tibia, forming interrupted, inverted U-shaped band together with pelvic spots when legs folded against body; skin of ventral side of head, trunk and limbs largely unpigmented and translucent; gular gland bright yellow; fingers and toes yellow (Fig. 12). During day, basic dorsal coloration light brown; dark brown dorsal speckles, spots and stripes in more pronounced contrast to basic coloration, more distinctly visible. Coloration in preservative. Dorsal basic coloration largely faded to light brown; darker dorsal pattern elements dark brown, clearly visible; color of gular gland, fingers and toes faded to white (Fig. 8D–F). Variation. The paratypes match the holotype in general appearance and proportions. Coloration and color pattern varies from light-cream to yellowish-orange with a few relatively large and darker blotches and vermiculation, light speckling and indistinct dorsolateral stripe to an almost reticulated pattern of contrasting bright and dark elements with a broad and conspicuous brown dorsolateral band (Fig. 12). Pedal webbing variation is I 1.5[100]/2+[100] II 1+[100]/2+[100] III 1 +[50],1.25[50]/2+[100] IV 2 [100]/1+[100] V. Bioacoustics. The advertisement call and other vocalizations are unknown. Ecology and natural history. We collected males and females in swamps in forest openings and near forest edges (Fig. 11B), from vegetation at the edge of streams (or on vegetation overhanging them) in forest, and from non-forest vegetation near the shore of Lake Tanganyika. Egg deposition has not been observed and tadpoles are unknown. An adult male (CAS 256035) was found in Bwindi Impenetrable National Park (Uganda) ca. 2 m above ground in a tree fern “either calling or moving to a calling site (similar to ‘running’ of Kassina)” (D. Blackburn, in litt., 22 July 2021). Laurent (1955) noted the species from transitional forest. In his paper on amphibians of Virunga National Park, Laurent (1972) noted the species is most commonly found in swamps with herbaceous vegetation in secondary forest, and more rarely, in primary forest. Laurent (1982) noted that, in general, the species is common in the foliage of shrubs in dense forests. He also recorded it from “une mare sombre” (i.e., a dark pond) in syntopy with Chiromantis at Kitutu (DRC), marshes where it reproduces by sticking its eggs under the leaves of fountain grass (Pennisetum, Shabunda, DRC), a shaded bank of a pond in syntopy with Hyperolius “ tuberculatus ” (likely H. hutsebauti sensu Bell et al. 2017) and H. frontalis; the center of this pond had reeds harboring H. kivuensis and Afrixalus orophilus (Shabunda, DRC). Laurent (1983:352) listed the species (along with Phrynobatrachus petropedetoides and Hyperolius frontalis) from “shadowy puddles of the thick transition forest.” Etymology. The species epithet is the Latin adjective “ lacustris,” meaning belonging to or dwelling in lakes; in allusion to the distribution of the new species in the region of the African Great Lakes. Distribution and conservation. The species is distributed from lowland rainforest of the Congo Basin at 460 m (Omaniundu, DRC, Laurent 1982) to transitional forests of the Albertine Rift at 1650 m (Mwana, DRC) and east as far as Mabira Forest, Uganda (1121 m). As shown in Figure 5, the species has a relatively large distribution, including several national parks and protected areas (e.g., Virunga National Park, Bwindi Impenetrable National Park), and thus is not likely to be threatened based on a limited distribution. Using GeoCAT, its extent of occurrence is estimated as 409,238 km ² and its area of occupancy as 160 km ² (Bachman et al. 2011). We therefore classify this species as Least Concern according to the IUCN Red List criteria (IUCN 2021). Four specimens (RMCA 77-020-B-133–136) from Tubutubu, Itombwe Plateau (2300 m) are problematic because they are morphologically consistent with A. lacustris, but they were collected from a substantially higher elevation than all other known specimens. Coordinates for Tubutubu provided by RMCA (4° S, 28.933° E) suggest the locality is east of the highest point of the plateau at an elevation of about 1400 m on Google Earth. Although it is possible that the specimens were collected at the latter elevation, Laurent (1982) mentions bamboo forest as the habitat, which usually occurs at the highest elevations of the Itombwe Plateau (Doumenge 1998). No clarity is offered by Laurent (1964), because he does not mention any Afrixalus in his study of the ecology and distribution of amphibians of the Itombwe Plateau. Given this conflicting information, we do not include the Tubutubu specimens in our current understanding of the elevational distribution of A. lacustris (see gray triangle in Fig. 5)., Published as part of Greenbaum, Eli, Portik, Daniel M., Allen, Kaitlin E., Vaughan, Eugene R., Badjedjea, Gabriel, Barej, Michael F., Behangana, Mathias, Conkey, Nancy, Dumbo, Bonny, Gonwouo, Legrand N., Hirschfeld, Mareike, Hughes, Daniel F., Igunzi, Félix, Kusamba, Chifundera, Lukwago, Wilber, Masudi, Franck M., Penner, Johannes, Reyes, Jesús M., Rödel, Mark-Oliver, Roelke, Corey E., Romero, Soraya & Dehling, J.

ELI 425), Chanjoka (02.21261° S, 28.77644° E, 2115 m), South Kivu Province, DRC. Diagnosis. The species is referred to the genus Afrixalus by exhibiting the following characteristics: fingers and toes webbed; tips of fingers and toes enlarged to discs; eye large; pupil vertically elliptical; tympanum indistinct; vomer ridges and teeth absent; dorsal surfaces finely shagreened with minute pointed tubercles; outer metatarsal tubercle distinct; gular gland in males. It is readily distinguished from most other members of the genus by its small size (SVL in males 20.1–24.6 mm, in females 22.6–26.4 mm), being smaller than A. dorsalis (males 25–28 mm, females 26–30 mm), A. fornasini (males 30–38 mm, females 35–40 mm), A. lacteus (males 22–27 mm, females 25– 29 mm), A. leucostictus (males 27–32 mm, females 25–36 mm), A. manengubensis (males to 32 mm), A. nigeriensis (males 28–34 mm, females 32–35 mm), A. osorioi (males 27–31 mm, females 32–35 mm), A. paradorsalis (males 28–34 mm, females 32–35 mm), A. septentrionalis (males 19–21 mm), and A. wittei (males 27–30 mm, females 29–33 mm); and larger than A. brachycnemis (males 18–21 mm, females 20–22 mm), A. delicatus (males 15–19 mm, females 17–22 mm), A. spinifrons (males to 20 mm, females to 25 mm), and A. stuhlmanni (males 15–21 mm, females 17–25 mm). Its differs in dorsal coloration and pattern from all species with longitudinal stripes or bands on a yellowish-brown background (A. brachycnemis, A. crotalus, A. delicatus, A. dorsalis, A. enseticola, A. fornasini, A. fulvovittatus, A. knysnae, A. morerei, A. orophilus, A. quadrivittatus, A. schneideri, A. spinifrons, A. stuhlmanni, A. upembae, A. septentrionalis, A. vittiger, and A. wittei); species with a conspicuous large dark dorsal blotch on a uniform background on anterior dorsum in combination with large blotches on both sides of the hip (A. leucostictus, A. manengubensis, A. osorioi, A. paradorsalis, and A. schneideri) or with longitudinal lateral dark bands (A. equatorialis and A. nigeriensis); species with a uniformly colored dorsum without conspicuous pattern except a dark dorsolateral stripe (A. aureus, A. clarkei, A. delicatus, A. fornasini, A. lacteus, A. leucostictus [dorsum with small white tubercles], A. uluguruensis, and A. weidholzi [might have a black vertebral line and dark brown flanks]); and from all remaining species having either dark stripes running from tip of snout to back, crossing each other and continuing as dorsolateral stripes (A. vibekensis, also males without asperities); anterior part of dorsum yellowish with brown pattern, posterior part of dorsum translucent (A. laevis, also males without asperities); posterior part of dorsum and dorsal sides of limbs semi-translucent with dense small dark white-edged speckles (A. dorsimaculatus); and dark blotches and transverse marks with white speckles (A. sylvaticus). The advertisement calls of the following species of Afrixalus consist of a long series of clicks, often initiated by a long buzzing note, and thus differ from the call of A. phantasma: A. aureus, A. brachycnemis, A. clarkei, A. crotalus, A. delicatus, A. dorsalis, A. fornasini, A. fulvovittatus, A. knysnae, A. nigeriensis, A. morerei, A. osorioi, A. quadrivittatus, A. septentrionalis, A. spinifrons, A. vibekensis, A. vittiger, A. weidholzi, and A. wittei. The advertisement calls of the remaining species for which information is available differ from the call of A. phantasma in the following characteristics (in parentheses): A. dorsimaculatus (soft, short buzzing rattle, usually repeated three times), A. equatorialis (series of five notes, repeated at 15–20/s and initiated by a long buzz, energy maximum at 2000–2500 Hz), A. lacteus (8–9 notes, 14–15 pulses,>300 pulses/s), A. paradorsalis (2–3 notes, energy maximum at 2700 Hz), A. stuhlmanni (2–9 notes, energy maximum at 4200–5100 Hz), and A. sylvaticus (2–5 notes, energy maximum at 4000–4500 Hz). The new species is most similar to A. lacustris sp. nov. from which it differs by a number of characteristics (see below). Description of holotype. Measurements of the holotype are provided in Table 2. Body very slender, widest at temporal region, slightly tapering to groin (Fig. 8A–C); head small (HL/SVL 0.31, HW/SVL 0.30), about as long as wide (HW/HL 0.98); snout relatively long, rounded in dorsal view and in lateral profile, slightly longer than wide; canthus rostralis hardly distinct, straight between eye and nostril; loreal region oblique; nostrils rounded, directed anterodorsally and slightly laterally; situated much closer to tip of snout and to eye, separated from each other by distance larger than distance between eye and nostril (IN/EN 1.15); eye directed anterolaterally, strongly protruding, very large (ED/HL 0.41), its diameter shorter than snout (ED/SL 0.84); interorbital distance much wider than upper eyelid and wider than internarial distance (IO/IN 1.21); tympanum covered by skin, not visible externally; upper jaw with dentition; teeth on premaxilla larger than teeth on maxilla; choanae small, located far anterolaterally at margins of roof of mouth, its anterior edge covered by maxillary bone, therefore appearing semicircular in ventral view; vomer ridges and teeth absent; tongue short and moderately broad, bilobed for about one-sixth of its length, free distally for about half its length; densely covered with minute papillae; median lingual process absent. Dorsal surfaces of head, trunk, and limbs and lateral surfaces of trunk finely shagreened; minute pointed, widely scattered tubercles on dorsum, more numerous posteriorly than anteriorly; supratympanic fold absent; small, subcircular, elevated glandular area in tympanic region posterior to eye and rear end of mandible, bearing large tubercles with pointed keratinous tips; ventral side of head smooth; vocal sac present; gular gland of vocal sac smooth, large and wide, covering about 70 percent of throat width (Fig. 8B); chest smooth, abdomen weakly areolate; ventral side of limbs smooth; short transverse fold above vent. Forelimbs slender;hand large (HND/SVL 0.32); tips of fingers enlarged into large disks, each with circummarginal groove; relative length of fingers: I I 2+/2.25 II 2/3+ III 2.75/2.25 IV; thenar tubercle oval, small and low, about one-fourth length of metacarpal of Finger I; palmar tubercles indiscernible. Hind limbs slender, moderately long; heel reaching to level of eye when legs adpressed forwardly to body; crus moderately long (TibL/SVL 0.48), about as long as thigh; heels meeting each other when knees flexed and thighs held perpendicularly to median plane; foot subequal in length to crus (FoL/TibL 0.96); relative length of toes: I I 2/2.25 II 1.5/3- III 1.75/3 IV 3-/1.75 V (Fig. 8C); inner metatarsal tubercle moderately prominent, elongated, about twothirds length of metatarsus of Toe I; outer metatarsal tubercle small, rounded. Coloration in life. During night, skin on dorsal side of head, trunk, forelimbs, crus and tarsus light yellowishbrown with more or less regular dark brown speckling; indistinct darker brown transverse stripe between upper eyelids; large dark brown, irregularly shaped spot in scapula region, two less distinct, somewhat lighter brown, irregularly shaped spots at level of anterior end of pelvis, separated from each other by half their width; cloacal region with dark brown mottling; dorsal skin of thigh largely unpigmented with only a broad stripe of widely scattered brown pigmentation; weak brown stripe along canthus, continuing behind eye on anterior half of trunk on both sides; tubercles below eye, and in tympanic region at rear end of jaw white; indistinct dark brown stripe running diagonally on middle of tibia, forming interrupted, inverted U-shaped band together with pelvic spots when legs folded against body; ventral side of head, trunk and limbs largely unpigmented and translucent; gular gland bright yellow; fingers and toes yellow (Fig. 7A). During day, basic dorsal coloration brighter, very light brown to bright cream-colored; dark brown dorsal speckles, spots and stripes in more pronounced contrast to basic coloration, more distinctly visible (Fig. 7B). Coloration in preservative. Dorsal basic coloration largely faded to yellowish white; darker dorsal pattern elements light to dark brown, clearly visible; yellow color of gular gland, fingers and toes faded to white (Fig. 8A–C). Variation. The paratypes match the holotype in general appearance, proportions, coloration and color pattern. Mensural variation within the species is shown in Table 1. Pedal webbing variation is I 2+[100]/2.5[90],2.25[10] II 2[50],2+[40],2.25[10]/3[10],3+[40],3.5[50] III 1.75 [80],2-[20]/3[100] IV 3 -[40],3[60]/1.75[100] V. Bioacoustics. Series of advertisement calls of six different males were recorded at the following ambient temperatures: 10.9°C (N = 1), 13.6°C (N = 3), and 16.2°C (N = 2). The advertisement call consisted of five to six, rarely four pulse groups (notes) (Fig. 9). Depending on the ambient temperature, notes were repeated at a rate of 7.1–10.0/s (10.9°C), 8.2–11.7/s (13.6°C), and 10.2–11.4/s (16.2°C). The highest repetition rate was always between the first three notes of a series, the lowest at the end of the series. Each note consisted of 10–11 pulses (Fig. 9). Probably due to echo effects, pulsation was often veiled in the waveforms, especially towards the end of the note. Pulse repetition rate varied from 190–210/s at 10.9°C, 222–250/s at 13.6°C, and 277–292/s at 16.2°C, resulting in a note length of 72–94 ms, 55–70 ms, and 36–50 ms, respectively. Amplitude modulation was prominent within individual notes (Fig. 9). Total call length showed linear temperature dependence and varied from 388–397 ms at 16.2°C, 472–499 ms at 13.6°C, and 572–620 ms at 10.9°C for five-note calls (Fig. 10). Energy maximum showed linear temperature dependence, with 3020–3150 Hz at 10.9°C, 3370–3550 Hz at 13.6°C, and 3660–3810 Hz at 16.2°C (Figs. 9–10). There was no marked frequency modulation. Prominent harmonics were at about 6000–7000 Hz and 9000–11000 Hz (Fig. 9). Ecology and natural history. We collected males and females in swamps in forest openings, or at forest edges (Fig. 11A). Males were found calling above standing bodies of water with thick lower vegetation cover. In Gishwati Forest and Kamiranzovu Swamp in Nyungwe Forest, the species was found calling in syntopy with Hyperolius castaneus and H. discodactylus. One adult male (UTEP 20802) from Kahuzi-Biega National Park (DRC) was found 3.5 meters above ground in montane forest. Tadpoles are unknown. Laurent (1955, 1983) listed the species from bushes in montane forest. Laurent (1982) noted that, in general, the species is common in the foliage of shrubs in dense forests. He also recorded it in banana trees in a deep valley (Nyungwe, Rwanda) and “des trous de prospection” (i.e., prospecting holes likely for gold mining, Upper Lubitshako, Kabobo Plateau, DRC). Etymology. The species epithet derives from the Greek noun φάντασμα (phántasma), meaning ghost or phantom, in allusion to the coloration and general appearance of the new species. The epithet is used as an invariable noun in apposition. Distribution and conservation. The occurrence of the species has been confirmed for several locations in western Rwanda (Nyungwe and Gishwati Forest) and eastern DRC (in and near Kahuzi-Biega National Park, Itombwe Plateau and Kabobo Plateau [Laurent 1982], Fig. 5). We expect the species to be eventually found in the AR of southwestern Uganda and northwestern Burundi. So far, the species has been recorded from only a narrow elevation range between 1962 m (Kamiranzovu Swamp, Rwanda) and ca. 2400 m (May ya Moto [and possibly Luemba], Itombwe Plateau, Laurent 1982). Given the relatively limited overall geographic distribution of the species with an estimated extent of occurrence of 19,088 km 2 (Fig. 5), an estimated area of occupancy of 52 km 2 (both calculated with GeoCAT; Bachman et al. 2011), the detection of the amphibian chytrid fungus in one adult male (UTEP 20791, Greenbaum et al. 2015), and the conservation challenges facing natural areas of the AR (Greenbaum 2017; Ayebare et al. 2018), we categorize this species as Vulnerable under the IUCN Red List criteria (IUCN 2021).

DESCRIPTION. — 51 specimens studied. Males 54.1-71.3 mm and females 54.3-75.6 mm. Body moderately wide and a wide head. Snout relatively pointed; skin smooth, but flat warts present on flanks and the posterior part of the back. Easily recognized by the colour pattern and distinct, broad white or yellow dorsolateral ridges (Rödel 2000). Colouration in alcohol dark brown with two white dorsolateral ridges and some grey spots on the limbs. Belly white. Males with a pair of lateral vocal sacs and large glands on the dorsal side of the upper arm. HABITAT. — We recorded A. galamensis in many habitats, i.e. agricultural zones, in water filled depressions of shrubby, grassy and wooded savannah. During the rainy season, we encountered the species around ponds and small water bodies in areas with sand and clay. subadult specimens were caught between cracks and small hollows at the edge of a permanent pond. The species occurs mostly along more permanent, larger waters in humid and dry savannah, including agricultural areas (Rödel 2000). In the dry season, this species can be found along river banks. The distribution area of the species, as currently understood, extends from extreme western Africa across to the horn of Africa and south into Angola, Mozambique, Zambia and Zimbabwe (Rödel & Bangoura 2004; Segniagbeto et al. 2007; Mohneke et al. 2011; Onadeko 2016; Böhme & Heath 2018). However, results by Jongsma et al. (2018) indicate that East African populations are not conspecific with those from West Africa., Published as part of Ayoro, Halamoussa Joëlle, Segniagbeto, Gabriel Hoinsoudé, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, Rödel, Mark-Oliver, Kabré, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on pages 574-575, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["BOHME W., MEINIG H. & RODEL M. - O. 1996. - New records of amphibians and reptiles from Burkina Faso and Mali.

Stout and robust frogs, with a moderately pointed snout, strong and long limbs. An inner and an external metatarsal tubercle present and very protruding as indicated by R��del (2000) and S��nchez-Vialas et al. (2017).

In life and alcohol, dorsal colouration from brown to dark grey. Presence of a wide white, yellow in life, vertebral line in all specimens. Species usually with a more granular dorsal skin, in comparison to other members of this genus (R��del 2000). HABITAT. ��� Specimens were captured in grasses near water bodies in Como��-L��raba Forest and Deux Bal�� National Park; on a trail near a water body in Arly National Park; under humid gasses at Dori pond and Yakouta dam banks. Ptychadena trinodis was one of the most abundant Ptychadena species at savannah ponds during the rainy season (Nago et al. 2006). The species is then virtually restricted to small or tiny water bodies which often lack vegetation (Guib�� & Lamotte 1957; Lamotte 1969; Schi��tz 1967; Perret 1981; R��del 2000). This species is distributed from West Africa east to northern Democratic Republic of Congo (R��del 2000; Padial & De La Riva 2004; S��nchez-Vialas et al. 2017; B��hme & Heath 2018)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on pages 572-573, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["MOHNEKE M., ONADEKO A.

In Como��-L��raba Forest, males were collected in shrubs on the edge of a large dark scorpion hole where they were calling. It was also found on the edge of water under a tree. A female was found on an anthill ready to withdraw into a hole. The species has been reported to often occur within ant nests and scorpion burrows (R��del & Braun 1999; R��del et al. 2013). It is known that P. microps colonizes various savannah habitats including dense tree savannah where it is found in flooded meadows, in ponds and swamps (Schi��tz 1967; R��del 2000; Hirschfeld & R��del 2011).

FIELD MATERIAL. ��� Burkina Faso ��� 2 ♀ (SVL 27.6-28.1 mm), 5 ♂ (SVL 24.4-26.5 mm), 3 subadults (SVL 16.6-18.3 mm); Nasso, Kou Forest; 11.18888��N, ��� 4.43935��W; 320 m a.s.l.; 7-9.VIII. 2018; H. J. Ayoro & A. Ohler leg.; gallery forest; hand capture. DESCRIPTION. ��� 20 specimens examined. Small frogs with a blunt snout, short head and a concave tympanum; slender limbs, the inner metatarsal tubercle long and prominent. Adult males and females with protruding palmar and supernumerary tubercles on fingers. Tubercles absent on toes. Dorsum feebly granulated. In life, dorsum grey, brown or reddish-brown coloured. Sometimes an hourglass pattern present on back (Fig. 3A, B). Venter with whitish or brownish, smooth skin. As other Arthroleptis species (e.g. Blackburn 2009; Blackburn et al. 2010), presence of an elongated third finger, and transparent spines on second and third fingers in adult males. HABITAT. ��� The historical specimens and the recent samples of A. poecilonotus were from Kou Forest (Fig. 2E). At this site, males were seen at night on leaves of shrub and grass at heights varying from 0.2- 1 m. Females and subadults were seen hiding in leaflitter. The species may occur in other gallery forests along the major rivers (Mouhoun, Como�� and Pendjari rivers) in the western and southern part of Burkina Faso as well (Lamotte 1967b). It was found in a forest close to a waterfall near Pendjari National Park in Benin (Nago et al. 2006), in Togo (Segniagbeto et al. 2007), in Ivory Coast (Lamotte & Perret 1963; Lamotte 1967b; Barbault & Trefaut-Rodrigues 1979; R��del 2000; R��del 2003; R��del & Ernst 2003) and in Nigeria (Schi��tz 1964, 1967; Leach�� et al. 2006; Onadeko 2016). TAXONOMIC REMARK. ��� As stated in R��del & Bangoura (2004) and Blackburn (2010), it is currently not possible to assign these West African Arthroleptis taxa with certainty to one of the various available names, as intra-specific variability equals or surpasses interspecific differences. As actually understood, A. poecilonotus has an extended distribution range, including West, Central and parts of East Africa (Frost 2019) and probably recovers a group of species. Type locality is in West Africa, in south-eastern Ghana. Further studies, in particular including topotypical material, are needed for taxonomic decisions., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 552, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["BLACKBURN D.

HABITAT. ��� Kassina senegalensis are fast moving among grasses and shrubs. Two vouchers were collected under bushy grasses from where they called and were difficult to localize. In Dori and Yakouta area, K. senegalensis was found on the ground under piles of pebbles near water, as well as in small holes or cattle footprints between grasses close to a pond. We heard other males calling from the base of thorny shrubs and piles of dry grass near a millet field. Kassina senegalensis was also found in Sahelian savannahs in Mauritania (Padial et al. 2013). It shelters under rocks or termite mounds during dry periods (Poynton & Broadley 1987; R��del 2000)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 562, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["SCHIOTZ A. 1967. - The treefrogs (Rhacophoridae) of West Africa.

DESCRIPTION. ��� 20 specimens studied. A plump, large and compact frog with a short and wide head (Fig. 6E, F). Its skin faintly warty and discontinuous ridges present on back. Measures for four females 95.3-129.5 mm SVL, thus larger than frogs from Benin (Nago et al. 2006) (female 90 mm and males 106-110 mm). Tympanum moderately large. Limbs relatively short and strong. A large inner metatarsal tubercle present. In life, dorsal colour greyish to green. Dori subadults and juveniles with a greenish colour and a white mediodorsal line. In W National Park, subadults with a dominantly greyish colour with large dark grey spots on the back (Fig. 6E, F). Adult females with olive green or light grey dorsal colouration. Belly white and throat yellow. REMARKS. ��� The taxonomy of West African Pyxicephalus Tschudi, 1838 needs revision (Nago et al. 2006; B��hme & Heath 2018). The West African specimens of this genus were in the past traditionally assigned to P. edulis Peters, 1854 which type locality is in Mozambique. The oldest available nomen for West African specimens is Rana maltzanii Boulenger, 1882, a replacement name for Maltzania bufonia Boettger, 1881. At the time of Boulenger (1882), Pyxicephalus Tschudi, 1838 was considered a subjective synonym of the genus Rana Linnaeus, 1758. Thus Boulenger (1882) considered Maltzania bufonia Boettger, 1881 as a secondary homonym of Rana bufonia Merrem, 1820 (valid as Elachistocleis surinamensis (Daudin, 1802)) (see Article 59.3 of the International Code of zoological Nomenclature for nomina replaced before 1961 for validity), and cannot be used as valid for the West African Pyxicephalus. The epithet Maltzania bufonia, as proposed by B��hme & Heath (2018), is permanently invalid and cannot be used for this taxon because the replacement name was���in use��� (e. g. cited as valid by Loveridge [1950] and Channing et al. [2012] listed in various synonymies of Pyxicephalus adspersus or Rana edulis; but the expression ���in use��� is quite imprecise). If we follow this taxonomic change, the nomen Rana maltzanii Boulenger, 1882 should be used as the valid name for Pyxicephalus maltzanii (Boulenger, 1882). Rana (Pyxicephalus) reiensis Monard, 1951 from Cameroon would be available if the central African populations proove to be taxonomically distinct. Thus here, we applied the name Pyxicephalus maltzanii to our voucher specimens, although a formal taxonomic revision including detailed morphological and molecular data is still pending. HABITAT. ��� This species was captured among grasses close to Dori and N���Djomga ponds. It was also found in Kabougou village near W National Park. Pyxicephalus maltzanii was recorded by gardeners in a banana plantation, vegetable gardens and paddy fields at D��dougou, Koti, Loumila and Koubri. Other authors indicate its presence in arid savannahs where it apparently prefers sand and clay substrates and it spends most of the year buried, appearing only to breed (Perret 1966; B��hme 1975). It is widely distributed in West Africa but rarely recorded; the species is almost everywhere eaten by the local population (R��del 2000; Nago et al. 2006; Mohneke et al. 2010b; Padial et al. 2013; B��hme & Heath 2018)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 573, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["BOULENGER 1882. - Catalogue of the Batrachia Salientia S.

The back with discontinuous, partly indistinct rows of elongate warts (Fig. 6D; Fig. 8A). A discontinuous white lateral line, extending from above the tympanum to the rear back. Dorsal colour greyish with some darker spots. COMMENTS. ��� Specimens identification based on the discontinuous dorsal ridges and their size (see Nago et al. 2006). However, in other parts of Africa, this name is applied to frogs which look completely different (larger and showing continuous dorsal ridges): see e.g. Channing (2001). Werner (1908) indicated in the original description a size ranging from 35-43 mm for the four females from Sudan. HABITAT. ��� The two males were captured on the edge of a small water body in the floodplain from Arly National Park. Ptychadena schillukorum inhabits dry savannahs and grasslands (Nago et al. 2006; S��nchez-Vialas et al. 2017) and it breeds in swampy valleys and savannah ponds during the rainy season (Nago et al. 2009). The species, as currently defined, is found across sub-Saharan savannahs of West and East Africa (Stewart 1967; Hughes 1988; Channing 2001; Mohneke et al. 2011; Sow et al. 2017)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 570, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["WERNER F. 1908 (1907). - Ergebnisse der mit Subvention aus der Erbschaft Treitl unternommenen zoologischen Forschungsreise Dr. Franz Werner's nach dem agyptischen Sudan und Nord- Uganda.

DESCRIPTION. ��� On 84 specimens examined, males��� SVL between 66.0- 105.2 mm (19 specimens) while females��� sizes between 69- 111.3 mm (38 specimens). Large and robust aquatic frogs. Eyes very prominent, in dorsal position. Head moderately broad with a rounded tympanum. Legs very strong and long, toes fully webbed. Dorsal skin with short warty and discontinuous folds, rather irregularly arranged. The dominant colouration greenish or grey olive on the back and white with some dark spots on the belly. juveniles showing a characteristic light yellow to green interorbital line. HABITAT. ��� Hoplobatrachus occipitalis is usually collected near or in water (R��del 2000). In the dry season it lives in rivers, pond banks and in irrigated wells. It is found in practically all freshwater habitats in wet season. Migrations were related in the dry season to the edge of rivers and the in wet season to surroundings of ponds (Spieler 1997). The species was observed on clayey and sandy soils. This frog is an important source of animal protein in the nutrition of local population from the south-eastern part of Burkina Faso (Mohneke et al. 2010b, 2011)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on pages 556-557, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["SCHIOTZ A. 1967. - The treefrogs (Rhacophoridae) of West Africa.

Amnirana albolabris (west) Jongsma et al. (2018) (Fig. 8B) COLLECTION MATERIAL. ��� Burkina Faso ��� 1 juvenile (SVL 16.1 mm); Houet province, in the forest of small-seminary at Nasso; 11.20953��N, ��� 4.43951��W; 340 m a.s.l.; 4.IV.1968; M. Lamotte leg.; MNHNRA-1999.7575. DESCRIPTION. ��� 1 specimen examined. Rather slender body with a triangular, depressed head and slightly rounded snout (Fig. 8B). Dorsal skin finely granular under the magnifying glass; two distinct dorsolateral folds present, from the posterior border of the eye to the sacrum. Dorsal colour dark brown, with few darker brown spots. REMARKS. ��� The genus Amnirana has been recently revised by Jongsma et al. (2018). Based on molecular data this study restricts the name Amnirana albolabris (Hallowell, 1856) to Central African populations, the populations from West Africa are clearly distinct and they are provisionally named Amnirana albolabris (west) (Jongsma et al. 2018). The type locality given for A. albolabris is ������West Africa������ by Hallowell (1856). However, Jongsma et al. (2018) searched the route of the collector Du Chaillu of the syntypes, and identified the area ���north of the Ogoou�� River in Gabon ��� as the type locality. Therefore, following Jongsma et al. (2018), we use for the West African populations the name A. albolabris (west) here. A formal description of this taxon is prepared by R��del and co-workers. HABITAT. ��� Amnirana albolabris (west) was collected in a gallery forest. We considered that place of collection could be Kou Forest which we visited in August 2018, what would be the northernmost site of its range. In other parts of its range the species inhabits pristine to heavily degraded rainforests and gallery forests in the savannah zones (R��del & Bangoura 2004; Kpan et al. 2014; Onadeko 2016)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 574, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["JONGSMA G.

Hyperolius lamottei Laurent, 1958 (Fig. 7B) COLLECTION MATERIAL. ��� Burkina Faso ��� 1♀ (SVL 21.6 mm); L��raba province, Katiar�� (north-east of Ferk��) close to Ivorian border; 9.91200��N, ��� 4.94776��W; 250 m a.s.l.; 10.XI.1970; M. Lamotte leg.; MNHN-RA-1997.9889. DESCRIPTION. ��� Female with a SVL of 21.6 mm. A small savannah frog with a SVL of 20-27 mm of both sexes (Lamotte & Xavier 1981; Schiotz 1999). Data based on additional specimens from various West African localities: males smaller than females; Ivory Coast 38♂ (19.5-23.1 mm), 32 ♀ (20.3-26.1 mm); Guinea 32 ♂ (18.0- 23.4 mm), 27 ♀ (20.0- 24.4 mm); Liberia 27 ♂ (19.5-23.8 mm), 37♀ (20.3-28.1 mm); Sierra Leone 54 ♂ (19.3-23.7 mm), 28 ♀ (21.8-27.3 mm). Slender frog, as Afrixalus vittiger. Back with 9 longitudinal bands: four white and five brown (Fig. 7B); see also figures inSchi��tz (1999), R��del & Ernst (2003), Adeba et al. (2010) and Channing et al. (2013). HABITAT. ��� Hyperolius lamottei was collected in Katiar��, north-east of Ferk�� region. This locality is situated in Cascades region in Burkina Faso, characterized by savannah and gallery forest areas with waterfalls, hills and cliffs. Based on the collection data of MNHN specimens from others localities of West Africa, H. lamottei inhabits wet savannah zones and seems to have a preference for montane regions such as the Nimba, Loma and P��ko mountains (Lamotte 1971; R��del & Ernst 2003; R��del et al. 2004), where it inhabits short grassland savannahs, often on granite ground (Schi��tz 1967; R��del & Ernst 2003). The Burkina Faso record is thus very unexpected and future field work should try to confirm its presence at the locality mentioned above and other similar sites., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 560, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["LAMOTTE M. & XAVIER F. 1981. - Les Amphibiens de l'Afrique de l'Ouest, in DURAND J.

DESCRIPTION. ��� 39 specimens examined. Voucher specimens morphologically similar to frogs described by R��del (2000). Similar to P. francisci but the warts on the neck often less distinct in P. latifrons. Breeding males with a completely smooth skin (Fig. 5F), (R��del 2000). A yellow vocal sac in males (black in P. francisci) and a more pronounced black lateral bands distinguishing P. latifrons from P. francisci. HABITAT. ��� This species was found on mud under dead wood and rocks at the edge of ponds in the dry season (Fig. 2A, B). During the rainy season, the species always lives close to water and we collected them on submerged grasses, under shrubs on the edge of little water bodies.

This species distinguished known from all other savannah frogs by a double, black vertebral line (Fig. 4F). HABITAT. ��� Kassina cassinoides and K. fusca Schi��tz, 1967 were calling at night from holes at the base of shrubs, at the beginning of rainy season. Three of our vouchers were collected on the ground near water (in about 10-50 m distance) in June and July. One was found on a tree where it was calling (in about 100 m from the water) in August. R��del (2000) also reported that single individuals may call from trees. It is most abundant in denser vegetated parts of dry savannah (R��del 2000; Nago et al. 2006). This species was not found in the Sahelian zone (Dori and Yakouta). Its distribution range covers a large part of the Sudano-Sahelian region in West Africa from Senegal to northeast Cameroon (Schi��tz 1999; B��hme 2005; Amiet 2012)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 561, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["SCHIOTZ A. 1999. - Treefrogs of Africa.

DESCRIPTION. ��� 15 specimens examined. Small frogs with a triangular head and a very pointed and short snout. Morphologically sturdy with strong limbs, adapted for burrowing (Fig. 4A). Skin soft and smooth (Laurent 1972; R��del 2000). Dorsal colouration of living frogs yellowish with some dark brown spots on the back. In alcohol, yellow colour whitish dorsally and ventrally. HABITAT. ��� Hemisus marmoratus was difficult to see during our survey periods and is probably much more abundant in convenient habitat and at the right saison. We found this fossorial species in the vicinity of a paddy field on the ���Ancien barrage��� edge in Koubri, on a trail leading to a small water body in W National Park. We heard the male calling under flooded grasses around a pond (1 km southwest of the Kabougou forest post office) in W National Park. The species was also found in Baboro swampy valley in Como��-L��raba where males could be heard calling among grasses nearby a small water body in Folonzo village swampy valley on 6 August 2018. This was unusual as Hemisus usually breeds in the early rainy season or even before the rains set in (see e.g. R��del et al. 1995; Kaminsky et al. 1999). In a floodplain near Bouliabou pond, we heard males calling and recorded three males in Arly National Park. In the Sahelian part, we captured this species during rainy weather on sandy soils close to a millet field in N���Djomga and on the roadside in Yakouta. Hemisus marmoratus is mostly fossorial, in relatively moist, loose soils and is often captured during earthworks such as plowing fields (Lamotte & Xavier 1981; R��del 2000). The species is common and reported having a wide distribution range from West Africa south to Angola and South Africa (Laurent 1972; R��del 2000). However, several cryptic taxa are probably mixed under this name (M.-O. R��del, unpublished data)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on pages 557-558, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["SCHIOTZ A. 1967. - The treefrogs (Rhacophoridae) of West Africa.

Sclerophrys mauritanica (Schlegel, 1841) (Fig. 7C) COLLECTION MATERIAL. ��� Burkina Faso ��� 1 ♀ (SVL 104 mm); Boulgou province, Garango; 11.79979��N, ��� 0.55053��W; 280 m a.s.l.; 18.VI.1962; M. Lamontellerie leg.; MNHN-RA-1989.4038. DESCRIPTION. ��� 1 specimen studied. Dorsum yellowish with large brown patches, bordered with black (Fig. 7A). Tympanum large and interorbital space concave. Parotoid glands kidney-shaped and parallel. Presence of double subarticular tubercles on the fourth toe. Characters corresponding to Salvador���s (1996) description of Sclerophrys mauritanica for northern Africa. HABITAT. ��� This toad is known from a wide variety of habitats, including rocky areas, grasslands, Mediterranean zones, oases, agricultural lands and urban areas (Salvador 1996; Ben Hassine & Nouira 2012). This species is reported from throughout northern Africa in an apparently continuous distribution between the Tunisian and Moroccan borders (Geniez et al. 2000; Ben Hassine & Escoriza 2017; Escoriza & Ben Hassine 2019). The presence of this species was reported by Lamotte & Xavier (1981) from Sub-Saharan areas like Burkina Faso but these authors did not mention any voucher specimens. The specimen of S. mauritanica in the MNHN is labelled as having been collected at Garango, in central-east of Burkina Faso, in VI.1962 by Michel Lamontellerie (1928-2013). The collector was an army doctor and stayed for over 20 years in this place. 109 specimens donated by Lamontellerie are present in the MNHN collections coming from Burkina Faso, Mali and France, but none from northern Africa. Nevertheless the collection locality of S. mauritanica in Burkina Faso should be regarded with some doubt, as it is more than 1000 km outside its southern range limit. Future research should carefully check toads from Burkina Faso, but also northern Mali and Niger for the potential presence of this species, south of the Sahara., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 575, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["SALVADOR A. 1996. - Amphibians of northwest Africa.

DESCRIPTION. ��� 71 specimens examined. Some of these specimens slightly larger than others. Male���s body size between 20.9-27.3 mm while female���s size 21.3-26.7 mm. Agreeing with Pickersgill (2007), indicating males body size from 21-26 mm and 22-28 mm for females. Skin asperities, typical for the genus, present on dorsum but also on belly, prominent on tarsus and feet in males. On back of all specimens, seven vertical distinct bands, four brown separated by three whitish (Fig. 4B). Ventral skin colour whitish. HABITAT. ��� We observed A. vittiger in floodplains and swampy valleys. The species is present in protected areas such as Arly National Park, W National Park, Como��-L��raba Forest and Deux Bal��s National Park. In Koubri, Pabr�� and Loumbila, the species was found in paddy fields, around ponds on grasses and plants surfacing water (Fig. 2C, D, F). It is a common savannah species which has a large distribution range in West Africa (R��del 2000; Leach�� et al. 2006; Nago et al. 2006; Segniagbeto et al. 2007). This species has often been confused with its congener A. fulvovittatus. The two species partly overlap in the forest-savannah ecotone of West Africa. However, Afrixalus fulvovittatus occurs in heavily degraded forest areas whereas A. vittiger mostly lives in savannah areas (Pickersgill 2007; R��del & Glos 2019)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 558, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["BOHME W., MEINIG H. & RODEL M. - O. 1996. - New records of amphibians and reptiles from Burkina Faso and Mali.

Presence of a wide white, green or red vertebral band in many specimens. HABITAT. ��� Ptychadena pumilio is ubiquitous in Guinean and Sudanese savannah and Sahelian habitats. It may even enter degraded rainforest (R��del 2000). We found it near water bodies among grasses and sometimes in the humid areas near water bodies in depressions, as well as in flooded zones in the rainy season. In Dori, we found calling males between flooded short grasses. In the dry season, P. pumilio was observed concealing under rocks, heaps of dry grass and cracks of dry mud around ponds and river banks, in Arly and W National Park from February to March 2017 and in Deux Bal��s National Park in November 2017., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on pages 568-570, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["MOHNEKE M., ONADEKO A.

Tomopterna milletihorsini (Angel, 1922) COLLECTION MATERIAL. ��� There are no voucher specimens available for this species from Burkina Faso although its presence was reported in the East and Central-East in this country in the literature. LITERATURE REPORTS. ��� Burkina Faso ��� Gourma province, Fada N���gourma; 12.06051��N, 0.34913��E; 300 m a.s.l. (Mohneke 2011; Mohneke et al. 2011) ��� Ganzourgou province, Zorgho; 12.2483��N, ��� 0.6278��W; 300 m a.s.l.; I-III.2008 (Mohneke et al. 2010b; Mohneke et al. 2011). DESCRIPTION. ��� Species with a short head, a horizontal pupil, short and strong limbs. Inner metatarsal tubercles large and shovel-shaped, tarsal tubercles usually present. Frog with a feebly warty back skin and smooth ventral skin. Dorsal colour brown to beige or dark brown. Pale dorsolateral lines often present. A white supratympanic ridge. Numerous dark brown, greenish or reddish spots, often with black borders, distinct on head, back and flanks. REMARKS. ��� The genus Tomopterna Dum��ril & Bibron, 1841 still comprises various undescribed species and needs taxonomic revision (Padial & De La Riva 2004; Padial et al. 2013). There are 14 species known in this genus and these are also known to be highly cryptic and morphologically similar (Wasonga & Channing 2013; Wilson & Channing 2019). The commonly used name for West African populations was Tomopterna cryptotis (Boulenger, 1907) (Lamotte & Xavier 1981; R��del 2000; Padial & De La Riva 2004; Mohneke 2011; Padial et al. 2013; Sow et al. 2017). Ohler & Fr��tey (2008) investigated the status of Arthroleptis milletihorsini (Angel, 1922), the type of which was deposited in MNHN collection. According to their examination, the characters did not correspond to the morphological characters of the genus Arthroleptis Smith, 1849, but rather to the characters of the genus Tomopterna Dum��ril & Bibron, 1841. The holotype is a young specimen of 18 mm SVL. Ohler & Fr��tey (2008) allocated the nomen Arthroleptis milletihorsini to Tomopterna, as Tomopterna milletihorsini (Angel, 1922) with the type locality being Kati 12 km north to Bamako from Mali. We tentatively use this name for West African Tomopterna. HABITAT. ��� During our field sampling, the presence of Tomopterna milletihorsini has been reported from Dori and Yakouta zones where gardeners and fishermen reported a frog species which inflate their body as Pyxicephalus maltzanii and is living under the sand. In Koti women indicated its presence as common in their groundnut fields after the harvesting (mostly from November to December). Women reported that the species was found by young shepherds who search it in sand in dried backwaters or in holes of groundnut fields after harvesting. In West Africa, Tomopterna is found in semiarid to arid habitats on sandy soils in the Sahel zone (R��del 2000; Padial & De La Riva 2004; Mohneke 2011). The species has been also found in mountains zones from Mauritania (Padial et al. 2013; Sow et al. 2017)., Published as part of Ayoro, Halamoussa Jo��lle, Segniagbeto, Gabriel Hoinsoud��, Hema, Emmanuel Midibahaye, Penner, Johannes, Oueda, Adama, Dubois, Alain, R��del, Mark-Oliver, Kabr��, Gustave Boureima & Ohler, Annemarie, 2020, List of amphibian species (Vertebrata, Tetrapoda) of Burkina Faso, pp. 547-582 in Zoosystema 42 (28) on page 574, DOI: 10.5252/zoosystema2020v42a28, http://zenodo.org/record/4265439, {"references":["MOHNEKE M., ONADEKO A.

Diagnosis. The genetic data (16 S rRNA) identifies the new species as a member of the genus Phrynobatrachus. Morphologically this is confirmed by: the general body shape; the presence of a tarsal tubercle; and the presence of pedal webbing. From the morphologically similar Arthroleptis they differ by lacking a median dorsal skin raphe and a black tympanic spot. From juvenile Ptychadena they can be distinguished by the lack of parallel dorsal ridges. Compared to other Phrynobatrachus the new species can be identified by the combination of the following characters: having snout-vent lengths smaller than 20 mm; males lacking tooth like projections in the lower jaw; males having black throats with spines; lacking a spiny eyelid tubercle; possessing a distinct lateral black facial mask; lacking X-shaped dorsal ridges; possessing comma-shaped dorsal ridges; lacking distinct markings on the whitish coloured belly; having yellowish ventral colouration on hind limbs; showing reduced pedal webbing and small but distinct discs on fingers and toes; and by a unique 16 S rRNA sequence. Differential diagnosis. The new species differs from other western African Phrynobatrachus species by: a small compact body (P. acridoides, P. africanus, P. auritus, P. batesii, P. brongersmai, P. cornutus, P. cricogaster, P. danko, P. francisci, P. giorgii, P. intermedius, P. jimzimkusi, P. latifrons, P. liberiensis, P. plicatus, P. natalensis, P. njiomock, P. sandersoni, P. schioetzi, P. steindachneri); lacking tooth like projections in lower jaw of males (present in P. africanus and P. sandersoni); a black lateral face mask originating from at least the level of eyes and extending to below the supratympanic ridge (black face mask only shared with: P. auritus, P. batesii, P. chukuchuku, P. intermedius, P. plicatus, P. ruthbeateae; less distinct brown face masks: P. werneri; some P. rainerguentheri have entirely black heads); small, but distinct tympanum (tympanum absent according to original description: P. ogoensis; indistinct but visible in BMNH 1947.2.6.83);

lower parts of hind limbs in both sexes uniform yellow (yellow colouration shared with: P. alleni, P. batesii, P. danko, P. manengoubensis, possibly also with P. sternfeldi; greyish/brownish to yellowish in P. ruthbeateae, P. schioetzi; vaguely dark blotched in P. hylaios); absence of spiny eyelid tubercles (spiny eyelid tubercle present in P. annulatus, P. calcaratus, P. cornutus, P. pintoi, P. taiensis, P. villiersi); comma-shaped scapular ridges converging towards vent (scapular ridges long and converging towards mid-body, almost X-shaped: P. alleni, P. auritus, P. brongersmai, P. jimzimkusi, P. plicatus, P. steindachneri; scapular ridges indistinct or absent: P. hieroglyphicus, P. intermedius, P. liberiensis, P. maculiventris, P. manengoubensis, P. tokba); short dorsolateral ridges often distinct (short dorsolateral ridges shared with: P. r u t h be a t e a e); dorsal skin granular (smooth: P. fraterculus, P. hieroglyphicus, P. maculiventris, most P. rainerguentheri, P. tokba; tuberculate: P. annulatus, P. calcaratus, P. cornutus, P. cricogaster, P. guineensis, P. sternfeldi, most P. guttursous, P. jimzimkusi, P. steindachneri, P. sternfeldi, P. taiensis, P. villiersi; the new species described below); ventral skin smooth in both sexes (ventral skin with asperities in both sexes: P. chukuchuku); absence of a blue band along the interior half of ventral shanks (present in P. auritus); absence of nuptial pads in males (nuptial pads or swollen thumb in males present: P. b at e s i i, P. e l b e r t i, P. guineensis, P. hieroglyphicus, P. maculiventris, P. ogoensis, P. werneri); distinct roundish discs on finger and toe tips (discs absent: most other species e.g. P. hieroglyphicus, P. intermedius, P. liberiensis, P. maculiventris, P. ogoensis, P. plicatus, P. rainerguentheri, P. tokba, P. werneri; discs heart-shaped: P. sandersoni); carpal gland in males lacking (carpal gland present: P. africanus); femoral glands absent (present in males: P. calcaratus, P. cornutus, P. fraterculus, P. leveleve, P. maculiventris, P. ogoensis, P. phyllophilus;

small round tarsal tubercle (numerous tarsal tubercles fused to tarsal ridge: P. cricogaster). Morphologically the new species can be only mistaken for P. ruthbeateae and P. ba t es i i. A detailed comparison with these two taxa is presented in the discussion. A comparison with the second new species described herein, is included in the diagnosis of the latter species.

Back and dorsal part of flanks more or less uniform brown; snout slightly clearer, dorsal with dark median spot, snout tip including anterior part of upper lip and loreal region light brown; clear spot between anterior part of eyelids; posterior part of inter-orbital space with dark bar; eyelids dark grey; lateral part of upper lip, sub-orbital region, supratympanic ridge and temporal area including tympanum dark brown to black, extending into a similarly coloured blotch on the anterior part of the upper arm; flanks posterior to forearm bases with large dark axillary blotch; brown flanks fainting ventrally into whitish belly; arms coloured as back, lower arm towards hand with two dark transversal bars; hands dorsally lighter coloured with dark crossbands; lower legs brown as back; thighs with 3-4 faintly indicated dark cross-bars; anterior part of thigh with dark longitudinal stripe, being the border to whitish ventral parts; lower leg dorsally with three (right) and four (left) dark cross-bars; feet and toes with dark cross-bands; dark blotch around vent, dorsally bordered by narrow yellowish line; lower parts of feet and hands greyish brown; remaining ventral parts of limbs and posterior part of belly uniform whitish; lateroventral parts of venter, anterior part of belly and pectoral region whitish but densely beset with minute black spots; throat and lower mandibles dark grey to black; lower mandibles with few small clear spots. Colouration in life (Fig. 1). Basic colour of dorsal surface of head, upper part of flank, back and dorsal surfaces of extremities light brown; snout, loreal region and anterior part of eyelids orange brown; snout with median longitudinal black spot; black inter-orbital bar; back with irregular darker patterning; lower arms, thighs, lower legs and feet with dark crossbars; anterior part of upper mandible brown with a dark bar; a V-shaped darker figure in scapular region, pointing anteriorly; black lateral face mask extending from below the eye and supratympanic ridge to forearm bases, covering tympanum; continuing below arms as a lateroventral black patch to axillar region; eye posterodorsally bordered by fine blue line; black pupil; iris copper red; central belly dirty white; belly laterally and pectoral area dark grey, no distinct black ventrolateral line or band; ventral part of forelimbs and hands dark grey; groin area and lower surfaces of thighs, lower leg and tarsus yellowish to orange; lower part of lower legs bordered by blackish spots; ventral surfaces of toes blackish. Variation (Figs. 1���2). Snout-vent length in males with spiny black throats (presumably indicating maturity) 13.5���15.8 mm and 13.1���19.7 mm in females (smallest one presumably not adult); body dimensions generally as in holotype, for small deviations see Table 1. The scapular ridges may differ in lengths and distinctness, but are always discernible and comma-shaped. Short dorsolateral ridges, composed of a very dense row of small warts, are visible in most specimens. Scapular and dorsolateral ridges are usually coloured dark. The webbing formulae showed some slight variation (Table 1). The black face mask may cover either the entire lateral parts of the head (sometimes with minute white spots; Figs. 2 c, d), extending from snout-tip to dorsal of the forearm insertion, or the parts anterior to the eye are coloured in clearer brown (Figs. 1, 2), sometimes with darker spots. Individuals with clearer coloured loreal regions also have dark brown upper mandible with black bars instead of entirely black mandibles. The back might be uniform dark or reddish brown, show some darker patterning, or carry a broad central dark band (Fig. 2 a). A light inter-orbital stripe is usually present. The iris colour varies from golden to copper red. The flank might be either uniform brown, grey or mottled with darker dots and lines (Fig. 2 c). The black axillary spot may be distinct and extending as far caudally as to about mid-body. Usually, the edges of this spot are irregularly shaped. In other individuals it is nothing but a rather indistinct mottling of blackish spots with clearer dots. We neither observed in males, nor in females distinct black bordering of belly and lower shanks as in P. ruthbeateae.

A.G. Zassi-Boulou & P. Moukala. Diagnosis. The genetic data (16 S rRNA) characterize the new species as a member of the genus Phrynobatrachus. Morphologically this is confirmed by: the general body shape and presence of a tarsal tubercle. From the morphologically similar Arthroleptis they differ by lacking a median dorsal skin raphe and a black tympanic spot; from juvenile Ptychadena they can be distinguished by lacking parallel dorsal ridges and pedal webbing. The new species can be distinguished from other Phrynobatrachus by the following combination of characters: small size; compact body shape; short round snout; absence of a black lateral mask, absence of a spiny eyelid tubercle; females with conspicuous ventral pattern with a white throat carrying the tip of a dark figure originating in the pectoral region, belly white; very conspicuous red blotch on anterior craniad bases of thighs, bordered by black line; short comma-shaped scapular ridges diverging posteriorly; dorsal skin tuberculate, warts particularly abundant and spiny on rear of back; flanks with some larger warts; absence of discs on finger and toe tips; no webbing and a unique 16 S rRNA sequence. Differential diagnosis. The new species differs from other western African Phrynobatrachus species by: body size being distinctly smaller than 20 mm (species with adults larger than 20 mm: P. acridoides, P. africanus, P. auritus, P. batesii, P. brongersmai, P. cornutus, P. cricogaster, P. danko, P. francisci, P. giorgii, P. intermedius, P. jimzimkusi, P. latifrons, P. liberiensis, P. plicatus, P. natalensis, P. njiomock, P. sandersoni, P. schioetzi, P. steindachneri); the absence of a spiny eyelid tubercles (spiny eyelid tubercle present in P. annulatus, P. calcaratus, P. cornutus, P. pintoi, P. taiensis, P. villiersi); absence of a dark lateral face mask (black face mask present: P. auritus, P. batesii, P. chukuchuku, P. horsti sp. nov., P. intermedius, P. plicatus, P. ruthbeateae; less distinct brown face mask: P. w e r ne r i); tympanum present���although not very distinct (tympanum absent according to original description: P. ogoensis; indistinct but visible in BMNH 1947.2.6.83); distinct short, chevron shaped pair of scapular ridges (scapular ridges long and converging towards mid-body, almost X-shaped: P. alleni, P. auritus, P. brongersmai, P. jimzimkusi, P. plicatus, P. steindachneri; scapular ridges indistinct or absent: P. hieroglyphicus, P. intermedius, P. liberiensis, P. maculiventris, P. manengoubensis, P. tokba); very tuberculate dorsal skin (smooth skin: P. fraterculus, P. hieroglyphicus, P. maculiventris, P. manengoubensis, P. tokba; almost smooth, scapular ridges present: P. rainerguentheri, P. schioetzi); ventral skin smooth (ventral skin with asperities: P. chukuchuku); absence of a very distinct large black axillary blotch or black band on flanks���anterior flank only with indistinct black pattern (distinct black blotches and/or bands on flank: P. dispar, P. fraterculus, P. gutturosus, P. maculiventris, P. pintoi, P. ruthbeateae; some P. cornutus); venter white with a dark triangle originating in pectoral region and tip extending to posterior part of throat (belly at least partly yellow in P. batesii, P. werneri; orange to yellow: P. danko; white or bluish with black pattern: P. villiersi; white with blackish spots or dots: P. annulatus, P. ghanensis, P. hylaios, P. maculiventris, P. pintoi; a black circle and median spot on white or yellow backgroundbull���s eye pattern: P. cricogaster; white with brown mottling: P. intermedius, P. jimzimkusi, P. njiomock, P. steindachneri); lower parts of hind limbs white with some dark patterning at the edges (yellow: P. alleni, P. batesii, P. danko, P. manengoubensis; greyish/brownish to yellowish in P. ruthbeateae, P. schioetzi; vaguely dark blotched in P. hylaios); absence of a blue band along the interior half of ventral shanks (present in P. auritus); presence of a distinct red spot at the anterio-dorsal bases of thighs, bordered by black line (not known in any other Phrynobatrachus); absence of pedal webbing (webbing well developed: P. acridoides, P. africanus, P. alleni, P. auritus, P. brongersmai, P. cricogaster, P. danko, P. elberti, P. francisci, P. giorgii, P. intermedius, P. jimzimkusi, P. latifrons, P. liberiensis, P. natalensis, P. njiomock, P. ogoensis, P. plicatus, P. rainerguentheri, P. steindachneri, P. sternfeldi); no discs on toe and finger tips (discs present, roundish: P. cornutus, P. guineensis, P. horsti, P. leveleve, P. phyllophilus, P. ruthbeateae, P. sternfeldi; discs heart shaped: P. sandersoni); small round tarsal tubercle (numerous tarsal tubercles fused to tarsal ridge: P. cricogaster). A detailed comparison with the genetically most similar species is given in the discussion. For further character states of western African Phrynobatrachus species see the literature cited at the end of the differential diagnosis paragraph for P. horsti sp. nov. Description of holotype [measures in mm]. Typical, small female Phrynobatrachus with short roundish, compact body shape; snout-vent length: 15.9; short snout, rounded in dorsal and lateral view; canthus rostralis rounded; loreal region straight; head-width directly behind the eyes: 5.5; large eyes positioned laterally; eyediameter: 2.1; distance anterior corner of eye to nostril: 1.5; nares small and round, positioned laterally; straight distance nostril-snout tip: 0.9; nostril much closer to snout than to eye; inter-narial distance: 2.0, much larger than inter-orbital distance (distance between eyelids): 1.1; pupil round; supratympanic ridge curving down from slightly ventrad of posterior corner of eye towards forearm bases (in preservation indistinct and vanishing just posterior to tympanum); tympanum indistinct, diameter: 0.9, no tympanic annulus; tympanum much smaller than diameter of eye; upper maxillae with minute teeth, hidden by lips; vomerine teeth absent; broad, almost heart shaped tongue, tip broad and almost straight, median conical papilla near tongue tip; tongue smooth to slightly granular; small round choanae positioned at anterior-lateral edges of mouth roof. Forelimbs long and slender; upper arm: 3.9; lower arm: 3.7; hand to tip of finger III: 3.8; hand with two large tubercles, oval thenar tubercle, large and round palmar tubercle; fingers with round, non-divided, protruding subarticular tubercles, no further tubercles on hand and fingers; relative finger length: IV���II=IColouration in ethanol after one year. Back and dorsal part of flanks and extremities light brown; snout almost uniform light brown; upper eyelids dark grey; interorbital area mottled dark brown; back posterior to scapular region with dark brown triangle, pointing towards head; posterior third of back slightly darker, large warts almost black; remaining back and flanks with few smaller and irregular shaped darker patches; lower arms with two indistinct dark cross-bars; anterio-dorsal part of femur���bordering groin area���with lighter area (red in life, see below), bordered by black line; femur and tibia with one distinct and 1-2 indistinct darker crossbars; foot and toes with dark crossbars; upper lip with three dark blotches on either side; tympanum carrying dark blotch; lower lip white with four dark blotches on either side; throat white with a black triangular figure pointing towards mouth tip, originating on level with forearm bases; belly white, anterior half with small round dark spots (two on right, three on left side); lower parts of extremities white, edges with greyish specking; lower part of thigh with some dark mottling. Colouration in life (Fig. 6). Basic colour of head, anterior two thirds of back, flanks and anterior extremities reddish brown; anterior part of eyelids and interorbital space with dark pattern; posterior parts of the two chevron like scapular ridges enclose a medial dark figure on the back; anterior part of flanks darker brown; upper lip with three dark patches on each side; tympanum with dark spot; upper two-thirds of iris brownish-golden, lower third greyish; bases of forearms almost white; elbow and lower arm with dark mottling. Basic colour of posterior third of back and dorsal parts of hind limbs dark brown; thighs, tibiae and feet with dark crossbars; warts on posterior part of back and lower legs reddish brown; dorso-craniad bases of thighs with large red blotch, bordered by distinct black line. Ventral colouration as in preservation. Variation. Paratype in bad state of preservation, flattened; right foot missing, right thumb short and fat (presumably healed injury); otherwise almost identical to holotype; back with slightly more dark patterning, crossbaring on extremities more pronounced; ventral pattern as in holotype. Measures are summarized in Table 4. Males are currently unknown. Genetics. Compared to 40 West African and Central African species of the genus Phrynobatrachus, P. mayokoensis sp. nov. exhibited a mean difference between 1.34���16.98 % in the sampled region of the 16 S rRNA gene (Table 5). The genetically most similar sample was a frog determined as P. ogoensis by Larson & Zimkus (2015; MCZ A- 149217, GenBank: KP 247505; the second most similar species being P. dispar with a mean difference of 5.27 %). However, a comparison of the new species with two P. ogoensis syntypes (BMNH 1947.2.6.83- 84) revealed that P. ogoensis is not conspecific with P. mayokoensis sp. nov. (see discussion). It thus seemed, that the Gabonese frog is either conspecific with P. mayokoensis sp. nov. or represents a further undescribed taxon. The intraspecific difference between the two P. mayokoensis specimens was 0.20 %. From the morphologically most similar species, P. cornutus, P. mayokoensis sp. nov. differed by 7.33���7.53 %. Genetically, Phrynobatrachus mayokoensis sp. nov. is most similar to various West and Central Africa species of the clade B sensu Zimkus et al. (2010). Distribution. Phrynobatrachus mayokoensis sp. nov. is only known from two localities in the Mayoko District of the Niari Department, south-western Republic of the Congo, close to the border with Gabon (Fig. 4). It might also occur in the Ogoou��-Ivindo Province of Gabon (Larson & Zimkus 2015; compare above). Habitat and natural history. The mid altitude habitat (740 m a.s.l.) of the holoytpe is shown in Figure 7 a. There it was encountered during the day (3: 15 pm), being active on the forest floor, within 20 m of a road. The nearest wetland was a stream about 180 m away at an altitude of 673 m. The habitat of the paratype (Fig. 7 b) likewise consisted of mid-altitude rainforest (704 m a.s.l.) on a slope. There were no wetlands within 100 m. At both sites the forest habitat seemed relatively dry compared to forest in the surrounding region. It seems possible that the species is reproducing independently of water or in small water bodies like tree holes and water filled snail shells (compare e.g. R��del & Ernst 2002 a, b; R��del et al. 2004). Etymology. The species��� name refers to the type locality situated in the Mayoko District of the Niari Department, Republic of the Congo. The specific epithet is considered an invariable noun in apposition to the generic name. The suggested English name for this new species is Mayoko Puddle Frog., Published as part of R��del, Mark-Oliver, Burger, Marius, Zassi-Boulou, Ange Ghislain, Emmrich, Mike, Penner, Johannes & Barej, Michael F., 2015, Two new Phrynobatrachus species (Amphibia: Anura: Phrynobatrachidae) from the Republic of the Congo, pp. 55-80 in Zootaxa 4032 (1) on pages 67-72, DOI: 10.11646/zootaxa.4032.1.3, http://zenodo.org/record/289765, {"references":["Larson, J.

ZMB 81732 (female; field # MBUR 3833), Republic of the Congo, Niari Department, Lekoumou, about 23 km E of Tsinguidi, about 4 km SE of Mayoko Posté, start of path to site 20, 740 m a.s.l., 02° 26 ’05.6’’ S, 12 ° 56 ’ 16.9 ’’ E, 18 November 2013, coll. M. Burger & A.G. Zassi-Boulou. Paratype. ZMB 81733 (female, field # MKO 001), Republic of the Congo, Niari Department, Mount Lekoumou, about 4 km south-east of Mayoko Posté, 704 m a.s.l., 02° 19 ’04.5’’ S, 12 ° 49 ’ 34.5 ’’ E, 31 March 2012, coll. A.G. Zassi-Boulou & P. Moukala. Diagnosis. The genetic data (16 S rRNA) characterize the new species as a member of the genus Phrynobatrachus. Morphologically this is confirmed by: the general body shape and presence of a tarsal tubercle. From the morphologically similar Arthroleptis they differ by lacking a median dorsal skin raphe and a black tympanic spot; from juvenile Ptychadena they can be distinguished by lacking parallel dorsal ridges and pedal webbing. The new species can be distinguished from other Phrynobatrachus by the following combination of characters: small size; compact body shape; short round snout; absence of a black lateral mask, absence of a spiny eyelid tubercle; females with conspicuous ventral pattern with a white throat carrying the tip of a dark figure originating in the pectoral region, belly white; very conspicuous red blotch on anterior craniad bases of thighs, bordered by black line; short comma-shaped scapular ridges diverging posteriorly; dorsal skin tuberculate, warts particularly abundant and spiny on rear of back; flanks with some larger warts; absence of discs on finger and toe tips; no webbing and a unique 16 S rRNA sequence. Differential diagnosis. The new species differs from other western African Phrynobatrachus species by: body size being distinctly smaller than 20 mm (species with adults larger than 20 mm: P. acridoides, P. africanus, P. auritus, P. batesii, P. brongersmai, P. cornutus, P. cricogaster, P. danko, P. francisci, P. giorgii, P. intermedius, P. jimzimkusi, P. latifrons, P. liberiensis, P. plicatus, P. natalensis, P. njiomock, P. sandersoni, P. schioetzi, P. steindachneri); the absence of a spiny eyelid tubercles (spiny eyelid tubercle present in P. annulatus, P. calcaratus, P. cornutus, P. pintoi, P. taiensis, P. villiersi); absence of a dark lateral face mask (black face mask present: P. auritus, P. batesii, P. chukuchuku, P. horsti sp. nov., P. intermedius, P. plicatus, P. ruthbeateae; less distinct brown face mask: P. w e r ne r i); tympanum present—although not very distinct (tympanum absent according to original description: P. ogoensis; indistinct but visible in BMNH 1947.2.6.83); distinct short, chevron shaped pair of scapular ridges (scapular ridges long and converging towards mid-body, almost X-shaped: P. alleni, P. auritus, P. brongersmai, P. jimzimkusi, P. plicatus, P. steindachneri; scapular ridges indistinct or absent: P. hieroglyphicus, P. intermedius, P. liberiensis, P. maculiventris, P. manengoubensis, P. tokba); very tuberculate dorsal skin (smooth skin: P. fraterculus, P. hieroglyphicus, P. maculiventris, P. manengoubensis, P. tokba; almost smooth, scapular ridges present: P. rainerguentheri, P. schioetzi); ventral skin smooth (ventral skin with asperities: P. chukuchuku); absence of a very distinct large black axillary blotch or black band on flanks—anterior flank only with indistinct black pattern (distinct black blotches and/or bands on flank: P. dispar, P. fraterculus, P. gutturosus, P. maculiventris, P. pintoi, P. ruthbeateae; some P. cornutus); venter white with a dark triangle originating in pectoral region and tip extending to posterior part of throat (belly at least partly yellow in P. batesii, P. werneri; orange to yellow: P. danko; white or bluish with black pattern: P. villiersi; white with blackish spots or dots: P. annulatus, P. ghanensis, P. hylaios, P. maculiventris, P. pintoi; a black circle and median spot on white or yellow backgroundbull’s eye pattern: P. cricogaster; white with brown mottling: P. intermedius, P. jimzimkusi, P. njiomock, P. steindachneri); lower parts of hind limbs white with some dark patterning at the edges (yellow: P. alleni, P. batesii, P. danko, P. manengoubensis; greyish/brownish to yellowish in P. ruthbeateae, P. schioetzi; vaguely dark blotched in P. hylaios); absence of a blue band along the interior half of ventral shanks (present in P. auritus); presence of a distinct red spot at the anterio-dorsal bases of thighs, bordered by black line (not known in any other Phrynobatrachus); absence of pedal webbing (webbing well developed: P. acridoides, P. africanus, P. alleni, P. auritus, P. brongersmai, P. cricogaster, P. danko, P. elberti, P. francisci, P. giorgii, P. intermedius, P. jimzimkusi, P. latifrons, P. liberiensis, P. natalensis, P. njiomock, P. ogoensis, P. plicatus, P. rainerguentheri, P. steindachneri, P. sternfeldi); no discs on toe and finger tips (discs present, roundish: P. cornutus, P. guineensis, P. horsti, P. leveleve, P. phyllophilus, P. ruthbeateae, P. sternfeldi; discs heart shaped: P. sandersoni); small round tarsal tubercle (numerous tarsal tubercles fused to tarsal ridge: P. cricogaster).

Measures are summarized in Table 4. Males are currently unknown. Genetics. Compared to 40 West African and Central African species of the genus Phrynobatrachus, P. mayokoensis sp. nov. exhibited a mean difference between 1.34–16.98 % in the sampled region of the 16 S rRNA gene (Table 5). The genetically most similar sample was a frog determined as P. ogoensis by Larson & Zimkus (2015; MCZ A- 149217, GenBank: KP 247505; the second most similar species being P. dispar with a mean difference of 5.27 %). However, a comparison of the new species with two P. ogoensis syntypes (BMNH 1947.2.6.83- 84) revealed that P. ogoensis is not conspecific with P. mayokoensis sp. nov. (see discussion). It thus seemed, that the Gabonese frog is either conspecific with P. mayokoensis sp. nov. or represents a further undescribed taxon. The intraspecific difference between the two P. mayokoensis specimens was 0.20 %. From the morphologically most similar species, P. cornutus, P. mayokoensis sp. nov. differed by 7.33–7.53 %. Genetically, Phrynobatrachus mayokoensis sp. nov. is most similar to various West and Central Africa species of the clade B sensu Zimkus et al. (2010). Distribution. Phrynobatrachus mayokoensis sp. nov. is only known from two localities in the Mayoko District of the Niari Department, south-western Republic of the Congo, close to the border with Gabon (Fig. 4). It might also occur in the Ogooué-Ivindo Province of Gabon (Larson & Zimkus 2015; compare above). Habitat and natural history. The mid altitude habitat (740 m a.s.l.) of the holoytpe is shown in Figure 7 a. There it was encountered during the day (3: 15 pm), being active on the forest floor, within 20 m of a road. The nearest wetland was a stream about 180 m away at an altitude of 673 m. The habitat of the paratype (Fig. 7 b) likewise consisted of mid-altitude rainforest (704 m a.s.l.) on a slope. There were no wetlands within 100 m. At both sites the forest habitat seemed relatively dry compared to forest in the surrounding region. It seems possible that the species is reproducing independently of water or in small water bodies like tree holes and water filled snail shells (compare e.g. Rödel & Ernst 2002 a, b; Rödel et al. 2004). Etymology. The species’ name refers to the type locality situated in the Mayoko District of the Niari Department, Republic of the Congo. The specific epithet is considered an invariable noun in apposition to the generic name. The suggested English name for this new species is Mayoko Puddle Frog.

Diagnosis. The genetic data (16 S rRNA) identifies the new species as a member of the genus Phrynobatrachus. Morphologically this is confirmed by: the general body shape; the presence of a tarsal tubercle; and the presence of pedal webbing. From the morphologically similar Arthroleptis they differ by lacking a median dorsal skin raphe and a black tympanic spot. From juvenile Ptychadena they can be distinguished by the lack of parallel dorsal ridges. Compared to other Phrynobatrachus the new species can be identified by the combination of the following characters: having snout-vent lengths smaller than 20 mm; males lacking tooth like projections in the lower jaw; males having black throats with spines; lacking a spiny eyelid tubercle; possessing a distinct lateral black facial mask; lacking X-shaped dorsal ridges; possessing comma-shaped dorsal ridges; lacking distinct markings on the whitish coloured belly; having yellowish ventral colouration on hind limbs; showing reduced pedal webbing and small but distinct discs on fingers and toes; and by a unique 16 S rRNA sequence. Differential diagnosis. The new species differs from other western African Phrynobatrachus species by: a small compact body (P. acridoides, P. africanus, P. auritus, P. batesii, P. brongersmai, P. cornutus, P. cricogaster, P. danko, P. francisci, P. giorgii, P. intermedius, P. jimzimkusi, P. latifrons, P. liberiensis, P. plicatus, P. natalensis, P. njiomock, P. sandersoni, P. schioetzi, P. steindachneri);

Forelimbs slender; upper arm: 3.4; lower arm: 3.6; hand to tip of finger III: 4.6; hand with two large tubercles, small and oval thenar tubercle, large and round palmar tubercle; carpal gland absent; fingers with round, nondivided, protruding subarticular tubercles, no further tubercles on hand and fingers; relative finger length: IV Dorsal skin fine granular (in life) to smooth (in preservation); a pair of long comma-shaped scapular ridges, ranging from about posterior corner of upper eyelid to slightly beyond level of forearm bases, converging towards vent; dorsolateral ridges faintly indicated; posterior edge of eyelid with few flat round warts, spiny eyelid tubercle absent; no white spines or warts on flanks; skin on outer parts of thighs and dorsal part of lower legs granular; skin on lower parts of limbs, belly and pectoral region smooth; throat without skin folds running parallel to mandibles; anterior third of lower mandible and anterior third of throat densely beset with rounded spines. Colouration in ethanol after 1.5 years. Back and dorsal part of flanks more or less uniform brown; snout slightly clearer, dorsal with dark median spot, snout tip including anterior part of upper lip and loreal region light brown; clear spot between anterior part of eyelids; posterior part of inter-orbital space with dark bar; eyelids dark grey; lateral part of upper lip, sub-orbital region, supratympanic ridge and temporal area including tympanum dark brown to black, extending into a similarly coloured blotch on the anterior part of the upper arm; flanks posterior to forearm bases with large dark axillary blotch; brown flanks fainting ventrally into whitish belly; arms coloured as back, lower arm towards hand with two dark transversal bars; hands dorsally lighter coloured with dark crossbands; lower legs brown as back; thighs with 3-4 faintly indicated dark cross-bars; anterior part of thigh with dark longitudinal stripe, being the border to whitish ventral parts; lower leg dorsally with three (right) and four (left) dark cross-bars; feet and toes with dark cross-bands; dark blotch around vent, dorsally bordered by narrow yellowish line; lower parts of feet and hands greyish brown; remaining ventral parts of limbs and posterior part of belly uniform whitish; lateroventral parts of venter, anterior part of belly and pectoral region whitish but densely beset with minute black spots; throat and lower mandibles dark grey to black; lower mandibles with few small clear spots. Colouration in life (Fig. 1). Basic colour of dorsal surface of head, upper part of flank, back and dorsal surfaces of extremities light brown; snout, loreal region and anterior part of eyelids orange brown; snout with median longitudinal black spot; black inter-orbital bar; back with irregular darker patterning; lower arms, thighs, lower legs and feet with dark crossbars; anterior part of upper mandible brown with a dark bar; a V-shaped darker figure in scapular region, pointing anteriorly; black lateral face mask extending from below the eye and supratympanic ridge to forearm bases, covering tympanum; continuing below arms as a lateroventral black patch to axillar region; eye posterodorsally bordered by fine blue line; black pupil; iris copper red; central belly dirty white; belly laterally and pectoral area dark grey, no distinct black ventrolateral line or band; ventral part of forelimbs and hands dark grey; groin area and lower surfaces of thighs, lower leg and tarsus yellowish to orange; lower part of lower legs bordered by blackish spots; ventral surfaces of toes blackish. Variation (Figs. 1–2). Snout-vent length in males with spiny black throats (presumably indicating maturity) 13.5–15.8 mm and 13.1–19.7 mm in females (smallest one presumably not adult); body dimensions generally as in holotype, for small deviations see Table 1. The scapular ridges may differ in lengths and distinctness, but are always discernible and comma-shaped. Short dorsolateral ridges, composed of a very dense row of small warts, are visible in most specimens. Scapular and dorsolateral ridges are usually coloured dark. The webbing formulae showed some slight variation (Table 1). The black face mask may cover either the entire lateral parts of the head (sometimes with minute white spots; Figs. 2 c, d), extending from snout-tip to dorsal of the forearm insertion, or the parts anterior to the eye are coloured in clearer brown (Figs. 1, 2), sometimes with darker spots. Individuals with clearer coloured loreal regions also have dark brown upper mandible with black bars instead of entirely black mandibles. The back might be uniform dark or reddish brown, show some darker patterning, or carry a broad central dark band (Fig. 2 a). A light inter-orbital stripe is usually present. The iris colour varies from golden to copper red. The flank might be either uniform brown, grey or mottled with darker dots and lines (Fig. 2 c). The black axillary spot may be distinct and extending as far caudally as to about mid-body. Usually, the edges of this spot are irregularly shaped. In other individuals it is nothing but a rather indistinct mottling of blackish spots with clearer dots. We neither observed in males, nor in females distinct black bordering of belly and lower shanks as in P. ruthbeateae. The inguinal region
