Body elongate, SVL 415 mm; TaL> 50 mm (tail tip lost); preventrals 2, ventrals 241; subcaudals 26 (tail tip lost), divided, weakly notched laterally; cloacal single; DSR 17-17-15; dorsal scales on the anterior 2/3 of the body length smooth, the six central dorsal scale rows of the posterior 1/3 of the body length feebly keeled; the vertebral scales not enlarged. Colouration in life: Head dark grey, without vertical light nuchal band; dorsal surface of body dark greyyellow with 87 greyish yellow irregular dorsal blotches; first body blotch starting at ventral scale 13, a half vertebral scale covered by this blotch; two yellow stripes on each side, from behind the neck to vent, indistinct posteriorly; ventral scales grey cream; dorsal surface of tail with at least eleven greyish yellow tail blotches, ventral surface of tail grey cream. Hemipenis: The left hemipenis is only in part everted but shows a spinose ornamentation. Additional specimen: One specimen which was not collected but detected and photographed on 22 July 2016 by an arachnology team consisting of Peter Jaeger, Aloke Sahu and Jonas Ewert, in Khammouane Province, in ca. 12.4 km distance from the type locality. The color pattern of this specimen resembles closely that of the holotype. Comparisons: In our phylogenetic analysis, Lycodon banksi sp. nov. is nested in a clade containing L. rufozonatus, L. semicarinatus (Cope), ‘ L. flavozonatus’, L. futsingensis and L. meridionalis. The new species differs from the similar L. meridionalis by having loreal entering the orbit (versus separated from the orbit), dorsal scales on the anterior 2/3 of the body length smooth, the six central dorsal scale rows on the posterior body third feebly keeled (versus distinctly keeled), dorsal head pattern uniform dark grey (versus with yellow-black marbling in L. meridionalis), and ventral surface grey cream (versus yellow with dark spots posteriorly) (see Bourret, 1935; Orlov & Ryabov, 2004); from L. rufozonatus by having loreal entering the orbit (versus usually separated), a distinctly higher ventral scale count (241 versus 185-204), dorsal scales feebly keeled in the posterior body part (versus all smooth), dorsal head pattern uniform dark grey (versus dark brown with yellow borders), and body pattern blotched (versus banded) (Boulenger 1893); from L. semicarinatus by having loreal touching the orbit (versus separated), a higher ventral scale count (241 versus 211-234), dorsal scale rows keeled along posterior 1/3 (versus keeled along anterior half), belly pattern uniform grey cream (versus yellow), and body pattern blotched (versus banded) (Boulenger 1893); from L. flavozonatus by having loreal in contact with the orbit (versus separated), cloacal single (versus divided), six dorsal scale rows on the posterior third of the body feebly keeled (versus 10-12 keeled dorsal scale rows at midbody), dorsal head dark grey (versus black with light markings), and belly pattern uniform grey cream (versus yellow with large black spots); from L. futsingensis by having loreal entering the orbit (versus separated), a higher ventral scale count (241 versus 193-203 in males), dorsal scales feebly keeled in the posterior body part (versus all smooth), and body pattern blotched (versus banded) (Vogel et al., 2012; Neang et al., 2014) (Table 4). The new species has a loreal entering the orbit and thus differs from the following species and subspecies of the Lycodon ruhstrati group which have the loreal separated from the orbit: L. cardamomensis Daltry & Wüster, 2002, L. davidi, L. multifasciatus (Maki, 1931), L. ophiophagus Vogel, David, Pauwels, Sumontha, Norval, Hendrix, Vu & Ziegler, 2009, L. paucifasciatus Rendahl in Smith, 1943, L. ruhstrati ruhstrati (Fischer, 1886), and Lycodon ruhstrati abditus (Vogel et al., 2009). In addition, the new species differs from L. cardamomensis by having more ventral scales (241 versus 215), and in body pattern (87 blotches versus 12 bands); from L. davidi by having more ventral scales (241 versus 224), six dorsal scale rows on the posterior third of the body feebly keeled (versus dorsal scale rows at midbody slightly keeled, outermost rows entirely smooth throughout body), and belly pattern uniform grey cream (versus anterior third whitishcream, posterior part heavily speckled with dark dots); from L. multifasciatus by having more ventral scales (241 versus maximum 237), and dorsal pattern blotched (versus banded); from L. ophiophagus by having more ventral scales (241 versus 211), and dorsal pattern (87 blotches versus 21-22 bands); from L. paucifasciatus by having fewer dorsal scale rows at neck (17 versus 19), more ventral scale rows (241 versus 221-222), six dorsal scale rows on the posterior third of the body feebly keeled (versus two upper rows plus vertebral row distinctly keeled), and dorsal pattern blotched (versus banded) (Neang et al., 2014); from L. r. ruhstrati and Lycodon ruhstrati abditus by having more ventral scales (241 versus 211-228; 241 versus 206-224, respectively), and dorsal pattern blotched (versus banded in the latter) (Vogel et al., 2012); from L. synaptor by having much more ventral scale rows (241 versus 201-203), dorsal pattern with 87 blotches (versus 30-31 bands), and belly pattern uniform grey cream (versus banded) (Vogel & David 2010); from L. zoosvictoriae by having more ventral scales (241 versus 213), dorsal pattern consisting of 87 blotches (versus 31), and having six dorsal scale rows on the posterior third of the body feebly keeled (versus all weakly keeled) (Neang et al., 2014). From the remaining species occurring in Laos, the new species can be distinguished as follows: from L. capucinus by having more ventrals (241 versus 182-211), fewer supralabials (8/8 versus 9-10), cloacal single (versus divided), dorsal blotches 87 (versus reticulated), and greyish yellow blotched body pattern (versus reticulated); from L. fasciatus by having more ventral scale rows (241 versus 182-225), dorsal pattern consisting of 87 blotches (versus 19-49 bands), and belly pattern uniform grey cream (versus white with dark blotches) (Neang et al., 2014); from L. laoensis by having loreal in contact with the orbit (versus separated), more ventrals (241 versus 169-192), and dorsal scales feebly keeled in the posterior body part (versus all smooth) (Neang et al., 2014); from L. septentrionalis by having more infralabials (10 versus 7-8), more ventral scales (241 versus 202-217), and dorsal pattern blotched (versus banded), as well as belly pattern uniform grey cream (versus white) (Neang et al., 2014); from L. subcinctus by the presence of preocular scale (versus absent), having cloacal scale single (versus divided), dorsal pattern blotched (versus banded in anterior part), and more ventral scale rows (241 versus 129-230) (Neang et al., 2014). From the remaining species in the fasciatus group, the new species differs as follows: from L. butleri Boulenger by having more ventral scale rows (241 versus 220-227), dorsal pattern blotched (versus banded), and belly pattern uniform grey cream (versus banded & spotted) (Grismer et al., 2014); from L. cavernicolus by having dorsal head uniformly dark grey (versus light brown), fewer supralabials (8 versus 9 or 10), more dorsal blotches (87 versus 36-45 bands), dorsal scales on the anterior 2/3 of the body length smooth, the six central dorsal scale rows of the posterior 1/3 of the body length feebly keeled (versus all keeled), and greyish yellow blotched pattern on the body (versus white bands); from L. gongshan by having six dorsal scale rows on the posterior third of the body feebly keeled (versus upper and vertebral dorsal rows keeled), more ventral scale rows (241 versus 210- 216), and dorsal pattern with 87 blotches (versus 32- 40 bands) (Vogel & Luo, 2011); from L. liuchengchaoi by having cloacal scale single (versus divided), dorsal pattern consisting of 87 irregular greyish yellow dorsal blotches (versus 40 well-defined yellow rings), and more ventral scales (241 versus 204) (Zhang et al., 2011). Distribution: Lycodon banksi sp. nov. is currently known only from the type locality in the Phou Hin Poun NPA, Khammouane Province, central Laos (Fig. 6). Etymology: The name of the species is dedicated to our friend and colleague Chris Banks, International Coordinator, Philippine Crocodile National Recovery Team, Zoos Victoria, Australia, for his outstanding contributions towards amphibian and reptile conservation, in particular of the Philippine Crocodile. We propose the following common names: Banks’ Wolf Snake (English), Banks Wolfszahnnatter (German). Natural history: The holotype was found at 20:39 h, crawling on a limestone outcrop in the karst forest, approximately 0.3 m above the forest floor, at an elevation of 167 m a.s.l. The humidity at the time of collection was approximately 85% and the air temperature ranged from 23 to 26 oC (Fig. 7). Another specimen was observed 12.4 km away from the type locality, active on the ground at 23:30 h, near a limestone cliff in the secondary forest.

In addition, the new species differs from L. cardamomensis by having more ventral scales (241 versus 215), and in body pattern (87 blotches versus 12 bands); from L. davidi by having more ventral scales (241 versus 224), six dorsal scale rows on the posterior third of the body feebly keeled (versus dorsal scale rows at midbody slightly keeled, outermost rows entirely smooth throughout body), and belly pattern uniform grey cream (versus anterior third whitishcream, posterior part heavily speckled with dark dots); from L. multifasciatus by having more ventral scales (241 versus maximum 237), and dorsal pattern blotched (versus banded); from L. ophiophagus by having more ventral scales (241 versus 211), and dorsal pattern (87 blotches versus 21-22 bands); from L. paucifasciatus by having fewer dorsal scale rows at neck (17 versus 19), more ventral scale rows (241 versus 221-222), six dorsal scale rows on the posterior third of the body feebly keeled (versus two upper rows plus vertebral row distinctly keeled), and dorsal pattern blotched (versus banded) (Neang et al., 2014); from L. r. ruhstrati and Lycodon ruhstrati abditus by having more ventral scales (241 versus 211-228; 241 versus 206-224, respectively), and dorsal pattern blotched (versus banded in the latter) (Vogel et al., 2012); from L. synaptor by having much more ventral scale rows (241 versus 201-203), dorsal pattern with 87 blotches (versus 30-31 bands), and belly pattern uniform grey cream (versus banded) (Vogel & David 2010); from L. zoosvictoriae by having more ventral scales (241 versus 213), dorsal pattern consisting of 87 blotches (versus 31), and having six dorsal scale rows on the posterior third of the body feebly keeled (versus all weakly keeled) (Neang et al., 2014). From the remaining species occurring in Laos, the new species can be distinguished as follows: from L. capucinus by having more ventrals (241 versus 182-211), fewer supralabials (8/8 versus 9-10), cloacal single (versus divided), dorsal blotches 87 (versus reticulated), and greyish yellow blotched body pattern (versus reticulated); from L. fasciatus by having more ventral scale rows (241 versus 182-225), dorsal pattern consisting of 87 blotches (versus 19-49 bands), and belly pattern uniform grey cream (versus white with dark blotches) (Neang et al., 2014); from L. laoensis by having loreal in contact with the orbit (versus separated), more ventrals (241 versus 169-192), and dorsal scales feebly keeled in the posterior body part (versus all smooth) (Neang et al., 2014); from L. septentrionalis by having more infralabials (10 versus 7-8), more ventral scales (241 versus 202-217), and dorsal pattern blotched (versus banded), as well as belly pattern uniform grey cream (versus white) (Neang et al., 2014); from L. subcinctus by the presence of preocular scale (versus absent), having cloacal scale single (versus divided), dorsal pattern blotched (versus banded in anterior part), and more ventral scale rows (241 versus 129-230) (Neang et al., 2014). From the remaining species in the fasciatus group, the new species differs as follows: from L. butleri Boulenger by having more ventral scale rows (241 versus 220-227), dorsal pattern blotched (versus banded), and belly pattern uniform grey cream (versus banded & spotted) (Grismer et al., 2014); from L. cavernicolus by having dorsal head uniformly dark grey (versus light brown), fewer supralabials (8 versus 9 or 10), more dorsal blotches (87 versus 36-45 bands), dorsal scales on the anterior 2/3 of the body length smooth, the six central dorsal scale rows of the posterior 1/3 of the body length feebly keeled (versus all keeled), and greyish yellow blotched pattern on the body (versus white bands); from L. gongshan by having six dorsal scale rows on the posterior third of the body feebly keeled (versus upper and vertebral dorsal rows keeled), more ventral scale rows (241 versus 210- 216), and dorsal pattern with 87 blotches (versus 32- 40 bands) (Vogel & Luo, 2011); from L. liuchengchaoi by having cloacal scale single (versus divided), dorsal pattern consisting of 87 irregular greyish yellow dorsal blotches (versus 40 well-defined yellow rings), and more ventral scales (241 versus 204) (Zhang et al., 2011). Distribution: Lycodon banksi sp. nov. is currently known only from the type locality in the Phou Hin Poun NPA, Khammouane Province, central Laos (Fig. 6). Etymology: The name of the species is dedicated to our friend and colleague Chris Banks, International Coordinator, Philippine Crocodile National Recovery Team, Zoos Victoria, Australia, for his outstanding contributions towards amphibian and reptile conservation, in particular of the Philippine Crocodile. We propose the following common names: Banks’ Wolf Snake (English), Banks Wolfszahnnatter (German). Natural history: The holotype was found at 20:39 h, crawling on a limestone outcrop in the karst forest, approximately 0.3 m above the forest floor, at an elevation of 167 m a.s.l. The humidity at the time of collection was approximately 85% and the air temperature ranged from 23 to 26 oC (Fig. 7). Another specimen was observed 12.4 km away from the type locality, active on the ground at 23:30 h, near a limestone cliff in the secondary forest., Published as part of Luu, Vinh Quang, Bonkowski, Michael, Nguyen, Truong Quang, Le, Minh Duc, Calame, Thomas & Ziegler, Thomas, 2018, A new species of Lycodon Boie, 1826 (Serpentes: Colubridae) from central Laos, pp. 263-276 in Revue suisse de Zoologie 125 (2) on pages 266-271, DOI: 10.5281/zenodo.1414221, {"references":["Bourret R. 1935.

Sexual dimorphism. Based on an examination of the four specimens (3 males and 1 female), we did not find significant differences in morphological characters between both sexes, except for the colour of compound eyes, being black in the female but yellow in males (Figs 2H, I). This finding is consistent with the observed sexes of S. puluongensis sp. nov., raising the possibility of using this character to distinguish both sexes of these two species. Biology. All four specimens were collected in the Pia Oac Nature Reserve. The habitat is primary forests at an elevation of 1220 m a.s.l. characterized by a forest canopy cover ranging from 76 to 95%. The percentage of exposed soil was 0–5%, with 6–25% herbaceous plant layer and leaf litter cover of 96–100%. The forests has a complex structure with various storeys. Dominant trees range from 20 to 30 m tall and belong mainly to two dominant families: Fagaceae (Castanopsis spp., Lithocarpus spp., Castanea spp.) and Lauraceae (Litsea spp., Cinnamomum spp., Machilus spp.), the herbaceous and parasitic plants comprised Poaceae, Asteraceae, Orchidaceae and Loranthaceae. Remarks. So far, Synapsis horaki was known only from the holotype specimen collected in the Tam Dao National Park, Vinh Phuc Province, northern Vietnam. The herein presented specimens constitute a new record for the Cao Bang Province and the first known female.

Sexual dimorphism. Based on an examination of the four specimens (3 males and 1 female), we did not find significant differences in morphological characters between both sexes, except for the colour of compound eyes, being black in the female but yellow in males (Figs 2H, I). This finding is consistent with the observed sexes of S. puluongensis sp. nov., raising the possibility of using this character to distinguish both sexes of these two species. Biology. All four specimens were collected in the Pia Oac Nature Reserve. The habitat is primary forests at an elevation of 1220 m a.s.l. characterized by a forest canopy cover ranging from 76 to 95%. The percentage of exposed soil was 0–5%, with 6–25% herbaceous plant layer and leaf litter cover of 96–100%. The forests has a complex structure with various storeys. Dominant trees range from 20 to 30 m tall and belong mainly to two dominant families: Fagaceae (Castanopsis spp., Lithocarpus spp., Castanea spp.) and Lauraceae (Litsea spp., Cinnamomum spp., Machilus spp.), the herbaceous and parasitic plants comprised Poaceae, Asteraceae, Orchidaceae and Loranthaceae. Remarks. So far, Synapsis horaki was known only from the holotype specimen collected in the Tam Dao National Park, Vinh Phuc Province, northern Vietnam. The herein presented specimens constitute a new record for the Cao Bang Province and the first known female. Morphometric measurements are summarized in the Table 1.

(continueđ) ......continued on the next page TABLE ��. (continueđ) Comparisons. Based on examination of specimens and data obtained from the literature (Boulenger 1907; Ota et al. 1995; R��sler et al. 2005, 2010, 2011; Yang et al. 2012, Nguyen et al. 2013; Luu et al. 2014; Ngo et al. 2015; Yang 2015; Luu et al. 2015) we compared the new species from Laos with the remaining members of the Gekko japonicus group (R��sler et al. 2011; Luu et al. 2015) (see Table 3). Morphologically, the new Gekko species can be distinguished from the species of the G. japonicus group (following R��sler et al. 2011; Luu et al. 2015) as follows: Gekko nadenensis sp. nov. does not have dorsal tubercles and thus differs from the following species which have tubercles on the back: G. adleri, G. auriverrucosus, G. canhi, G. chinensis, G. japonicus, G. hokouensis, G. kwangsiensis, G. liboensis, G. palmatus, G. scabridus, G. shibatai, G. similignum, G. swinhonis, G. vertebralis, and G. wenxianensis. The new species can be distinguished from G. aaronbaueri by having fewer interobital scales (28���30 versus 34���37), more scale rows around midbody (123���140 versus 98���104), and more precloacal pores in males (6 versus 3���4); from G. melli by its smaller size (SVL reaching 77.1 mm versus 84.6 mm), fewer interorbitals (28���30 versus 34���40), internasals absent (versus present), postmentals enlarged (versus not enlarged), and fewer precloacal pores in males (6 versus 9���11); from G. subpalmatus by having fewer interorbitals (28���30 versus 32), postmentals enlarged (versus not enlarged), the absence of internasals (versus present), having fewer ventral scales (38���40 versus 48), and precloacal pores in a discontinuous row in males (versus in a continuous row); from G. taibaiensis by its larger size (SVL reaching 77.1 mm versus 69 mm), having more supralabials (12���14 versus 9���10), and more lamellae under first and fourth toes (13���15 versus 6��7 and 14���16 versus 7 or 8, respectively); from G. tawaensis by the lack of internasals (versus 2), having postmentals enlarged (versus not enlarged in G. tawaensis), and precloacal pores present (versus absent); from G. truongi by its smaller size (SVL reaching 77.1 mm versus 95.9 mm), having fewer interobital scales (28���30 versus 45���48), more scales from mental to cloacal slit (175���185 versus 160���172), and fewer precloacal pores in males (6 versus 10���11); and from G. yakuensis by lacking internasals (versus having), having postmentals enlarged (versus not enlarged), fewer precloacal pores in males (6, in a discontinuous row versus 6���8, in a continuous row), and the absence of tubercles on dorsal surface of tail (versus presence). Gekko nadenensis sp. nov. is similar to G. bonkowskii, G. thakhekensis, G. scientiadventura, and G. sengchanthavongi in body size and dorsal pattern. However, the new species can be distinguished from G. bonkowskii by having more interorbitals (28���30 versus 26���27), precloacal pores in a discontinuous row in males (versus in a continuous row), more scales from mental to cloacal slit (175���185 versus 154���169), and more scale rows at midbody (123���140 versus 117); from G. thakhekensis by having more interorbitals (28���30 versus 22���26), more precloacal pores in males (6, in a discontinuous row versus 1���5, in a continuous row), more scales from mental to cloacal slit (175���185 versus 165���174), and more scale rows at midbody (123���140 versus 110���116); from G. scientiadventura by having fewer interorbitals (28���30 versus 41���51), and precloacal pores in a discontinuous row in males (versus in a continuous row), and more scales from mental to cloacal slit (175���185 versus 118���140); from G. sengchanthavongi by having more precloacal pores in males (6 versus 4���5), more supralabials and infralabials (12���14 versus 8��10 and 10���12 versus 6���7, respectively), dorsal head pattern with light grey blotches and a grey stripe behind the orbit (versus dark and grey spots), and dorsal body pattern with light grey blotches and brown flecks (versus irregular transverse dark brown bars). For more details see Table 4. Distribution. Gekko nadenensis sp. nov. is currently known only from the type locality in the karst forest of Nang Log cave, Naden Village, Gnommalath District, Khammouane Province, central Laos (Fig. 3). Etymology. We name this species after its type locality, Naden Village, to underscore the importance of the limestone forest in terms of biodiversity and nature conservation. From this site another new gecko species (Cyrtodactylus rufford) was described recently (Luu et al. 2016). We suggest as common names: Naden Gecko (English), Kap Ke Naden (Laotian), and Naden Gecko (German). Natural history. Specimens of the new species were collected between 19:30 and 22:00, on a karst cliff near the entrance of and inside Nang Log Cave, from 0.3 m to 3 m above the ground, at elevations between 158 and 178 m a.s.l. (Fig. 4). The humidity was approximately 70���80% and the air temperature ranged from 18 to 26o C. The new species co-occurs with the recently described bent-toed gecko Cyrtodactylus rufford (Luu et al. 2016). The female paratype, which was collected in March 2015 contained two eggs. In February 2016, we found a mass egglaying site (about 2 m above the ground) in a dark and narrow corner of a rock crevice system at the mouth of the Nang Log cave. Some of the eggs had not yet hatched (Fig. 5)., Published as part of Luu, Vinh Quang, Nguyen, Truong Quang, Le, Minh Duc, Bonkowski, Michael & Ziegler, Thomas, 2017, A new karst dwelling species of the Gekko japonicus group (Squamata: Gekkonidae) from central Laos, pp. 179-193 in Zootaxa 4263 (1) on pages 181-190, DOI: 10.11646/zootaxa.4263.1.10, http://zenodo.org/record/572614, {"references":["Luu, V.

A new species, the third one from Vietnam, of the genus Aporcelinus is described from natural areas. Aporcelinus falcicaudatus sp. n. is characterized by its 1.28 to 1.63 mm long body, lip region offset by weak constriction and 16 to 18 mm broad, odontostyle 18 to 21 mm at its ventral side, neck 354 to 406 mm long, uterus tripartite and 61 to 95 mm long, V = 50 to 55, tail strongly recurved dorsad and conical (23–31 mm, c = 43–58, c9 = 0.7–0.9) with finely rounded tip, and male absent. Scanning electron microscope (SEM) study, the first of a representative of the genus, shows a lip region pattern significantly different from that observed in the typical aporcelaimid taxa.

Sectonema caobangense sp. n. from evergreen forest soil in Vietnam is described, including scanning electron micrograph (SEM) observations and D2-D3 LSU rDNA analysis. The new species is characterized by its 3.12 to 5.80mmlong body, lip region offset by deep constriction and 21 to 23 mm broad, mural tooth 13 to 14 mm long at its ventral side, 940 to 1,112 mm long neck, pharyngeal expansion occupying 61% to 69% of total neck length, uterus a long simple tube-like structure 292 to 363 mm long or 2.7 to 2.9 times the corresponding body diameter, pars refringens vaginae well developed, V = 48 to 56, short (36–51 mm, c = 77–132, c9 = 0.5–0.8) and rounded tail, 87 to 99 mm long spicules, and four or five irregularly spaced ventromedian supplements bearing hiatus. Sectonema caobangense sp. n. differs from the typical pattern of Sectonema in the nature of the stomatal protrusible structure, bearing a mural tooth attached to the ventral side of the stoma. Molecular data obtained and the derived evolutionary trees support a close phylogenetic relationship with other Sectonema species.

This species is very similar to A. mamillatus (Williams, 1959) ��lvarez-Ortega & Pe��a- Santiago, 2011 in its general morphology and many morphometrics, but it can be distinguished by several significant differences: broader lip region (21���22 vs 19���20 ��m), smaller odontostyle (22���24 vs 25���29 ��m, 1.1���1.2 vs 1.3���1.5 times the lip region diameter, n= 9) with shorter aperture (46���50 vs 57���61 % of its total length), more posterior S 2 N (92 vs 83���86) and more posterior vulva (V = 53���54 vs V = 49���52). Type locality and habitat. Northern Vietnam, Cat Ba National Park, Hai Phong Province (GPS coordinates: 20 �� 47 ' 45 '' N and 107 �� 00' 40 ''E, elevation 170 m), in soil of a secondary forest with Cinnamomum sp. as the dominant plant species. One female was collected near the same location in the rhizosphere of Zea mays L. growing in an area of intensive agricultural crops alongside the National Park. Type material.

Cyrtodactylus rufford sp. nov. has a contiguous series of femoral and precloacal pores in males and thus differs from the following species which have poreless scales separating femoral from precloacal pores: C. bichnganae Ngo & Grismer, C. brevipalmatus (Smith), C. dumnuii Bauer, Kunya, Sumontha, Niyomwan, Pauwels, Chanhome & Kunya, C. erythrops Bauer, Kunya, Sumontha, Niyomwan, Panitvong, Pauwels, Chanhome & Kunya, C. huongsonensis Luu, Nguyen, Do & Ziegler, C. interdigitalis, C. khelangensis Pauwels, Sumontha, Panitvong & Varaguttanonda, and C. tigroides Bauer, Sumontha & Pauwels. Cyrtodactylus rufford sp. nov. has 42���43 femoral and precloacal pores in males and thus differs from the following species which have distinctly fewer femoral and precloacal pores: C. auribalteatus Sumontha, Panitvong & Deein (10���11), C. caovansungi Orlov, Nguyen, Nazarov, Ananjeva & Nguyen (15), C. chanhomeae Bauer, Sumontha & Pauwels, C. intermedius (Smith) (8���10), C. kingsadai Ziegler, Phung, Le & Nguyen (7���16), C. roesleri (20���28), and C. soudthichaki (29). Cyrtodactylus rufford sp. nov. can be distinguished from C. astrum Grismer, Wood, Quah, Anuar, Muin, Sumontha, Ahmad, Bauer, Wangkulangkul, Grismer & Pauwels by its smaller size (maximum SVL 72.5 mm versus 108.3 mm), having fewer ventral scale rows (27���29 versus 31���46), fewer lamellae under the fourth toe (18��� 19 versus 20���24), and more femoral and precloacal pores in males (42���43 versus 31���38); from C. jarujini Ulber by its smaller size (maximum SVL 72.5 mm versus 90.0 mm), having fewer ventral scale rows (27���29 versus 32���38), and fewer femoral and precloacal pores in males (42���43 versus 52���54); from C. lekaguli Grismer, Wood, Quah, Anuar, Muin, Sumontha, Ahmad, Bauer, Wangkulangkul, Grismer & Pauwels by its smaller size (SVL reaching 72.5 mm versus 103.5 mm), having fewer ventral scales (27���29 versus 31���43), and more femoral and precloacal pores in males (42���43 versus 30���36); from C. multiporus by its smaller size (maximum SVL 72.5 mm versus 98.0 mm), having fewer ventral scale rows (27���29 versus 30���38), and fewer femoral and precloacal pores in males (42��� 43 versus 58���60); from C. teyniei David, Nguyen, Schneider & Ziegler by its smaller size (maximum SVL 72.5 mm versus 89.9 mm), having fewer ventral scale rows (27���29 versus 38), the presence of a nuchal band (versus being absent), and having a banded dorsal pattern (versus blotched). Cyrtodactylus rufford sp. nov. is similar to the members of the C. phongnhakebangensis group (Nazarov et al. 2014) including C. khammouanensis, C. lomyenensis, C. jaegeri, C. darevskii, and C. phongnhakebangensis Ziegler, R��sler, Herrmann & Vu in having a high number of femoral and precloacal pores and in the dorsal pattern. However, the new species can be distinguished from C. khammouanensis by having fewer ventral scale rows (27��� 29 versus 32���38), fewer dorsal tubercles at midbody (14���16 versus 16���21), fewer lamellae under the fourth toe (18���19 versus 20���23), dorsum of head with dark blotched markings (versus absent), having light transverse bands between limb insertions with wavy margins (versus transverse bands with smooth margins), and tail with light rings (versus light bands); from C. lomyenensis by having fewer ventral scale rows (27���29 versus 35���36), fewer supralabials (10���12 versus 13���14), and more femoral and precloacal pores in males (42���43 versus 39���40); from C. darevskii by its smaller size (maximum SVL 72.5 mm versus 100.0 mm), having fewer ventral scale rows (27���29 versus 38���46), and fewer ventral scales between mental and cloacal slit (153���167 versus 180���208); from C. jaegeri by having fewer ventral scale rows (27���29 versus 31���32), fewer femoral and precloacal pores in males (42���43 versus 44), fewer lamellae under the fourth toe (18���19 versus 20���23), and having irregular shaped light transverse bands between limb insertions (versus regular shaped light transverse bands); and from C. phongnhakebangensis by its smaller size (maximum SVL 72.5 mm versus 96.3 mm), having fewer ventral scale rows (27���29 versus 32��� 42), generally more femoral and precloacal pores in males (42���43 versus 32���42), and fewer ventral scales between mental and cloacal slit (153���167 versus 180���208). For more details see Table 5. Distribution. Cyrtodactylus rufford sp. nov. is currently known only from the type locality in the karst forest near Daen Village, Gnommalath District, Khammouane Province, central Laos (Fig. 4). Etymology. The new species is named in honour of the Rufford Foundation (UK) for its support to herpetofaunal research and conservation in Laos. The species epithet is to be treated as a noun in apposition, invariable. As common names, we suggest Ki Chiem Rufford (Laotian) and Rufford Bent-toed Gecko (English). Natural history. The type series of the new species was found between 20:00 and 21:00, on a karst cliff near the entrance of Nang Log Cave, from 0.3 m to 2 m height above the forest floor, at elevations between 160 and 180 m a.s.l. Nang Log Cave is situated within an isolated karst mountain surrounded by secondary forest, plantations, and some huts for tourists. The cave is a tourism site, only 50 m distant from Road 12 and 64 km from the border of Vietnam. The humidity was approximately 80 % and the air temperature ranged from 24 to 26 o C (Fig. 5). Other species found on the same karst wall within a 300 meters range of the type locality were the lizard Gekko gecko (Linnaeus), and the tree frog species Rhacophorus spelaeus Orlov, Gnophanxay, Phimminith & Phomphoumy, as well as the Huntsman Spider Heteropoda maxima Jaeger, and the long-legged cave centipede Thereuopoda longicornis (Fabricius).

Comparisons. We compared the new species with its congeners from Laos and neighbouring countries in the mainland Indochina region, including Vietnam, Cambodia, and Thailand based on examination of specimens (see Appendix) and data integrated from the literature (compiled after Luu et al. 2014 a; Nazarov et al. 2014; Nguyen et al. 2014; Panitvong et al. 2014; Pauwels et al. 2014; Pauwels & Sumontha 2014; Schneider et al. 2014; Sumontha et al. 2015; Nguyen et al. 2015; Luu et al. 2015 a; Luu et al. 2016 a, b) (see Tables 3). The cluster and correspondence analyses of morphological characters supported Cyrtodactylus hinnamnoensis sp. nov. as a sister taxon to C. darevskii (Figs. 2–3). Molecular phylogenetic analyses also demonstrated the close relationships between these species (see Fig. 1). Morphologically, Cyrtodactylus hinnamnoensis sp. nov. is closely related to the C. phongnhakebangensis group including C. darevskii, C. phongnhakebangensis, C. calamei by dorsal colour pattern and the number of cloacal and femoral pores in males. However, the new species can be distinguished from C. darevskii by having fewer cloacal and femoral pores in females (maximum 0–28 versus 24–34), four to six blackish brown transverse body bands, as wide as light bands (versus four to five dark irregular transverse breaking body bands, 0.5 times narrower than light band), first body band wide, butterfly-shaped (versus thin, U-shaped in C. darevskii), the presence of tubercles on fore limbs (versus absent), and tail consisting of light rings (versus banded); Cyrtodactylus hinnamnoensis sp. nov. differs from C. phongnhakebangensis by its slightly larger size (SVL reaching 100.6 mm versus 96.3 mm), having fewer cloacal and femoral pores in females (0–28 versus 0–41), having more scale rows from mental to the front of cloacal slit (179–201 versus 161–177), the presence of tubercles on fore limbs (versus absent), a narrower nuchal loop, not enlarged posteriorly (wide, enlarged posteriorly), four to six blackish brown transverse body bands as wide as light bands (versus three to five dark transverse body bands as wide as double light bands, light transverse bands with small spots (versus with big black blotches), and tail pattern consisting of light rings (versus banded); Cyrtodactylus hinnamnoensis sp. nov. differs from C. calamei by its larger size (SVL reaching 100.6 mm versus 89.3 mm), fewer cloacal and femoral pores in females (0–28 versus 38), more postcloacal tubercles (4–6 versus 4), dorsal head marking with distinctly dark spots and blotches (versus indistinct dots), the absence of heart-shaped marking on postocciput (versus present), four to six blackish brown body = standard deviatiοn, fοr οther abbreviatiοns see material and methοds). ……continued on the next page transverse bands, as wide as light bands (versus four greyish brown transverse bands, narrower than light bands) (for more details see Table 7, Fig. 9). The results of the correspondence analysis comparing all adult male morphological maesurements of Cyrtodactylus hinnamnoensis sp. nov. and the latter species indicated four distinct groups between these species (see Fig. 4). Distribution. Cyrtodactylus hinnamnoensis sp. nov. is currently known only from the type locality in the karst forest of Hin Nam No NPA, Khammouane Province, central Laos (Fig. 6). Etymology. We name this species after its type locality, Hin Nam No NPA where the new Cyrtodactylus species was discovered and propose the following common names: Hinnamno Bent-toed Gecko (English), Ki Chiem Hin Nam No (Laotian). Natural history. Specimens were found at night between 19: 41 and 22:03h on karst walls, ca. 0.3–5 m above the ground, near cave entrances in the limestone forest, at elevations between 175 and 580 m a.s.l. Only one male specimen VNUF R. 2014.99 was collected on a tree trunk, about 1 m from the forest floor. The surrounding habitat was karst forest, dominated by species of Ebenaceae, Dracaenaceae, Arecaeae, Poaceae, Meliaceae, and Moraceae. The relative humidity ranged from 78 % to 90 %, and temperatures were from 24.9 to 30.7 o C (see Table 8). When capturing individuals of the species, we observed an increased rate of tail autotomy and many individuals had regenerated tail, for example, seven of 11 specimens of Cyrtodactylus hinnamnoensis sp. nov. had dropped or/and regenerated tails. This suggests that these populations might be under the stress of predators (see also Grismer et al. 2016).

Cyrtodactylus phongnhakebangensis group Species. C. bansocensis, C. calamei, C. darevskii, C. hinnamnoensis, C. jaegeri, C. jarujini, C. khammouanensis, C. lomyenensis, C. multiporus, C. pageli, C. rufford, C. sommerladi, C. soudthichaki, C. teyniei. Characters. Adult SVL 73���100.6 mm, supranasals 0���1; dorsal tubercles 10���24 (except for C. sommerladi, which only has 0���5); webbing between fingers and toes absent; tubercles on fore limbs lacking (except for C. calamei, C. hinnamnoensis, C. jaegeri, C. jarujini, C. multiporus, and C. soudthichaki); tubercles on hind limbs present (except for C. pageli); precloacal and femoral pores in males 20���60 (except for C. pageli only four and for C. teyniei such data is lacking); postcloacal tubercles 3���8 (rarely two); subcaudals enlarged; body bearing welldefined bands 3���8 (except for C. jarujini and C. teyniei, which are blotched). Distribution. The group is mainly distributed in the karst forest mountains of Khammouane Province in central Laos, C. calamei, C. hinnamnoensis, and C. sommerladi are restricted to Hin Nam No NPA in the southeastern Khammouane Province. C. jarujini and C. teyniei are recorded from Bolikhamxay Province, while C. pageli is only known to occur in Vientiane Province. Remarks. The Cyrtodactylus phongnhakebangensis group is very complex. Different morphological traits of the species of this group (e.g., body size, shape and number of dorsal bands, and number of precloacal and femoral pores, see Tables 7 & 13) were supported by other morphological and phylogenetic analyses (see Figs. 1���5). All species of the group are adapted to karst forested formations., Published as part of Luu, Vinh Quang, Bonkowski, Michael, Nguyen, Truong Quang, Le, Minh Duc, Schneider, Nicole, Ngo, Hanh Thi & Ziegler, Thomas, 2016, Evolution in karst massifs: Cryptic diversity among bent-toed geckos along the Truong Son Range with descriptions of three new species and one new country record from Laos, pp. 101-140 in Zootaxa 4107 (2) on page 132, DOI: 10.11646/zootaxa.4107.2.1, http://zenodo.org/record/266526

Cyrtodactylus species groups in Laos As currently recognized, 21 Cyrtodactylus species are known from Laos. Based on our molecular phylogeny, the molecular data presented in Nazarov et al. (2014), and a combination of characters including size, dorsal color pattern, scalation, and geographic distribution, we herein propose four species groups within the genus Cyrtodactylus occurring in Laos (see Table 13), which are defined as follows

Cyrtodactylus interdigitalis group Species. C. interdigitalis. Characters. Adult SVL 80.0 mm, supranasal single; dorsal tubercle rows 18; webbing between fingers and toes present; tubercles on limbs present; number of precoacal and femoral pores in males 16���18; postcloacal tubercles 1���2; tail dorsally with tubercles; without enlarged subcaudals; dorsal body blotched or ambiguous. Distribution. The species is known to occur in central Laos including Vientiane and Khammouane provinces. It is adapted as a tree-dweller, but in contrast to the C. irregularis species group that lives near the base of trees, C. interdigitalis is found higher on tree trunks and in tree crowns., Published as part of Luu, Vinh Quang, Bonkowski, Michael, Nguyen, Truong Quang, Le, Minh Duc, Schneider, Nicole, Ngo, Hanh Thi & Ziegler, Thomas, 2016, Evolution in karst massifs: Cryptic diversity among bent-toed geckos along the Truong Son Range with descriptions of three new species and one new country record from Laos, pp. 101-140 in Zootaxa 4107 (2) on page 135, DOI: 10.11646/zootaxa.4107.2.1, http://zenodo.org/record/266526

Male: Prerectum 2.3, cloaca 1.7 times the body diameter at the cloacal aperture. Genital system diorchic, with opposite testes. In addition to the adcloacal pair, located at 9 ��m from the cloacal aperture, there is a series of 12 low, regularly spaced (10���16 ��m apart) ventromedian supplements, the most posterior three located within the range of spicules. Spicules dorylaimid, 4.6 times longer than wide and 1.8 times longer than body diameter at the cloacal aperture: dorsal side regularly convex and ventral side with barely perceptible hump and hollow; curvature 136 ��; head 8 x 7 ��m, with the dorsal side somewhat longer than the ventral one and weakly curved; median piece occupying less than one-third (29 %) of maximum spicule width, reaching the posterior end of the spicule and with a visibly furcate tip; posterior end of spicules 6 ��m wide. Lateral guiding pieces 17 ��m long or 6.1 times as long as wide, slightly sigmoid and tapering posteriorly. Tail straight ventrally, dorsally first convex and then very weakly concave. Diagnosis. The new species is characterized by its 1.20���1.46 mm long body, lip region offset by constriction and 16���18 ��m broad, odontostyle 20 ��m at its ventral side or 1.1���1.4 times the lip region diameter, neck 354���368 ��m long, pharyngeal expansion 175���186 ��m long or 49���51 % of total neck length, a dorsal cell mass present at the pharyngo-intestinal junction, uterus tripartite and 176���241 ��m, or 2.4���2.7 times the corresponding body diameter, long, V = 52���54, tail conical with acute tip and slightly recurved dorsad (33���42 ��m, c = 33���45, c��� = 0.9���1.2), spicules 62 ��m long, and 12 regularly spaced ventromedian supplements, three of them within the range of spicules. Relationships. The new species is very similar to A. seychellensis Andr��ssy, 2011 in its general morphology and morphometrics, but differs from the type population of that species in its larger general size (body length 1.20���1.46 (n = 4) vs 0.92���1.07 mm (n= 4); neck length 354���368 vs 272���330 ��m), much larger genital branches (17���21 % vs 7���13 % of total body length each), more posterior vulva (V = 52���54 vs V = 45���52), shorter female tail (32���36 vs 36���40 ��m, c = 33���45 vs c = 25���29) and male present (vs absent). Especially relevant in the type population are the very short female genital branches, probably because the uterus is short and simple. Vinciguerra et al. (2014) studied two A. seychellensis populations from Ecuador that differ from the type populations in their larger general size [body 1.08���1.55 (n= 26) vs 0.92���1.07 (n = 4) mm long] and comparatively shorter female tail (c = 29���42 vs c = 25���29). Besides, the female genital branches are larger (12���22 vs 7���13 % of total body length), but lower values in the Ecuador material may be due to the convoluted, tripartite uterus. Leaving aside the fewer ventromedian supplements (7���9 vs 12; two vs three situated within the range of spicules) in males from Ecuador, there is no significant difference between this material and the Vietnamese specimens herein studied. Taking into consideration that only one male of the new species has been collected, the differences in number and arrangement of ventromedian supplements are provisionally regarded as intraspecific variability and, consequently, we consider the specimens from Ecuador and Vietnam to be conspecific. Type locality and habitat. Northern Vietnam, Cat Ba National Park, Hai Phong Province (GPS coordinates: 20 �� 47 ' 45 '' N and 107 �� 00' 40 ''E, elevation 170 m), collected from soil in a tropical forest with Cinnamomum sp. as dominant plant species. Other locality and habitat.

Three females and one male from two locations, in acceptable condition. Morphometrics. See Table 2. Locality Cat Ba National Park Huu Lien Natural Reserve (Hai Phong Province) (Lang Son Province) Habitat Cinnamomum sp Machilus sp. and Dimocarpus Holotype Paratypes sp. Description. Adult: Stout (a = 16–20) nematodes of medium size, 1.20–1.46 mm long. Habitus variably curved ventrad upon fixation, C-shaped in female, G-shaped in male. Cuticle two-layered, 3–4 µm thick at anterior region, 3.5 –5.0 µm in mid-body and 4.0– 6.5 µm on tail; inner layer thicker and more refractive than the outer layer. Lateral chord 9 µm broad or 10–13 % of mid-body diameter. Body pores often obscure, but two cervical pores are visible on both dorsal and ventral sides at level of odontostyle plus odontophore. Lip region angular, offset by constriction; lips high, separated, with protruding labial and cephalic papillae. Amphid fovea cup-shaped, its opening 9–11 µm broad or 53–63 % of lip region diameter.

Male: Prerectum 2.3, cloaca 1.7 times the body diameter at the cloacal aperture. Genital system diorchic, with opposite testes. In addition to the adcloacal pair, located at 9 µm from the cloacal aperture, there is a series of 12 low, regularly spaced (10–16 µm apart) ventromedian supplements, the most posterior three located within the range of spicules. Spicules dorylaimid, 4.6 times longer than wide and 1.8 times longer than body diameter at the cloacal aperture: dorsal side regularly convex and ventral side with barely perceptible hump and hollow; curvature 136 º; head 8 x 7 µm, with the dorsal side somewhat longer than the ventral one and weakly curved; median piece occupying less than one-third (29 %) of maximum spicule width, reaching the posterior end of the spicule and with a visibly furcate tip; posterior end of spicules 6 µm wide. Lateral guiding pieces 17 µm long or 6.1 times as long as wide, slightly sigmoid and tapering posteriorly. Tail straight ventrally, dorsally first convex and then very weakly concave. Diagnosis. The new species is characterized by its 1.20–1.46 mm long body, lip region offset by constriction and 16–18 µm broad, odontostyle 20 µm at its ventral side or 1.1–1.4 times the lip region diameter, neck 354–368 µm long, pharyngeal expansion 175–186 µm long or 49–51 % of total neck length, a dorsal cell mass present at the pharyngo-intestinal junction, uterus tripartite and 176–241 µm, or 2.4–2.7 times the corresponding body diameter, long, V = 52–54, tail conical with acute tip and slightly recurved dorsad (33–42 µm, c = 33–45, c’ = 0.9–1.2), spicules 62 µm long, and 12 regularly spaced ventromedian supplements, three of them within the range of spicules. Relationships. The new species is very similar to A. seychellensis Andrássy, 2011 in its general morphology and morphometrics, but differs from the type population of that species in its larger general size (body length 1.20–1.46 (n = 4) vs 0.92–1.07 mm (n= 4); neck length 354–368 vs 272–330 µm), much larger genital branches (17–21 % vs 7–13 % of total body length each), more posterior vulva (V = 52–54 vs V = 45–52), shorter female tail (32–36 vs 36–40 µm, c = 33–45 vs c = 25–29) and male present (vs absent). Especially relevant in the type population are the very short female genital branches, probably because the uterus is short and simple. Vinciguerra et al. (2014) studied two A. seychellensis populations from Ecuador that differ from the type populations in their larger general size [body 1.08–1.55 (n= 26) vs 0.92–1.07 (n = 4) mm long] and comparatively shorter female tail (c = 29–42 vs c = 25–29). Besides, the female genital branches are larger (12–22 vs 7–13 % of total body length), but lower values in the Ecuador material may be due to the convoluted, tripartite uterus. Leaving aside the fewer ventromedian supplements (7–9 vs 12; two vs three situated within the range of spicules) in males from Ecuador, there is no significant difference between this material and the Vietnamese specimens herein studied. Taking into consideration that only one male of the new species has been collected, the differences in number and arrangement of ventromedian supplements are provisionally regarded as intraspecific variability and, consequently, we consider the specimens from Ecuador and Vietnam to be conspecific. Type locality and habitat. Northern Vietnam, Cat Ba National Park, Hai Phong Province (GPS coordinates: 20 º 47 ' 45 '' N and 107 º 00' 40 ''E, elevation 170 m), collected from soil in a tropical forest with Cinnamomum sp. as dominant plant species. Other locality and habitat. Northern Vietnam, Huu Lien Natural Reserve, Lang Son Province, (GPS coordinates: 21 º 42 ' 51 '' N and 106 º 21 ' 48 ''E, elevation 502 m), in soil of the forest where the dominant plant species were Machilus sp. and Dimocarpus sp. Type material. Female holotype, female paratype and male paratype deposited in the nematode collection of the University of Jaén, Spain. One female paratype deposited in the nematode collection of the Institute of Ecology and Biological Resources (IEBR), Hanoi, Vietnam. Etymology. The specific epithet means ‘near seychellensis ’ as the new species resembles A. seychellensis in many aspects.

Phasmid situated at 29���34 % of tail length. Male: Unknown. Diagnosis (based on the 6 specimens studied). This species is characterized by its body length (306���347 ��m in females), lateral field with two alae or 3���4 longitudinal incisures, lip region with three pairs of asymmetrical conoid lips, three low and rounded labial probolae separate from the corresponding pair of lips by an incisure, Ushaped primary axils without guard processes, V-shaped secondary axils without guard processes, pharyngeal corpus slightly fusiform and 2.6���3.1 times the isthmus length, spermatheca and post-vulval sac poorly developed, female tail conoid (18���24 ��m, c = 12.7 ���17.0, c��� = 1.8���2.7) with rounded terminus ending in an acute or wartshaped mucro, and phasmid at 29���34 % of tail length. Males are unknown. Locality and habitat. Pia Oac (GPS coordinates: 22 �� 36 ' 28 ''N and 105 �� 52 ' 15 ''E, elevation 1150 m), Cao Bang Province, Vietnam, collected from the rhizosphere of Zea mays L. growing in an area of intensive agricultural crops alongside the Pia Oac Natural Reserve. * Measurements from drawings, ** from other measurements. Discussion. Cephalobus topali was originally described from only one female and three larval specimens. The material herein studied perfectly fits Andr��ssy���s (1970) description. The SEM observations reported here provide additional information that raises doubt about the position of this species. For example, instead of connecting the corresponding adjacent pairs of lips, a typical diagnostic feature of the genus Cephalobus Bastian, 1865 (see Abolafia & Pe��a-Santiago 2009), the labial probolae of the specimen examined here are clearly separated from the lips by an incisures (Fig. 3 A���C). This fits the pattern observed in representatives of the genus Acrobeloides (Cobb, 1924) Thorne, 1937 (see Abolafia & Pe��a-Santiago, 2003). Consequently, this species is transferred to the genus Acrobeloides as A. topali (Andr��ssy, 1970) comb n. Andr��ssy (1984) regarded C. topali as identical to and a junior synonym of Cephalobus quadrilineatus Eroshenko, 1968, only known to occur in Russian Far East Territories. Both species have similar morphology and morphometry (see comparison in Table 1), and both have an acute mucro at the tail tip. Later, however, Andr��ssy (2005) maintained both species as valid, but examination of specimens of the Russian species is necessary to confirm it. Provisionally, we accept that the two species are valid as differences between them were noted: isthmus size (as long as vs one-third of the corresponding body diameter), excretory pore location (at level of the corpusisthmus junction vs at isthmus posterior portion, near the basal bulb), presence of a short vs absence of a postvulval sac, and rectum length (as long as vs shorter than the corresponding body diameter). The distribution of A. topali appears to be restricted to the north of Vietnam, associated with modified soils. Andr��ssy (1970) found it among grass roots in the municipal cemetery of the district of Yen So (Hanoi), and here it is reported from further north, in agricultural plots opened in the rain forest, close to the Pia Oac Natural Reserve. In the last two years, several hundred specimens of nematodes have been examined from this area but, only a few specimens of this rare species were found, and none came from natural, unaltered areas., Published as part of Nguyen, Thi Anh Duong, Bonkowski, Michael, Pe��a-Santiago, Reyes & Abolafia, Joaqu��n, 2016, Re-description of Cephalobus topali Andr��ssy, 1970 (Rhabditida, Cephalobidae) from Vietnam, and transfer to Acrobeloides (Cobb, 1924) Thorne, 1937, pp. 593-600 in Zootaxa 4092 (4) on pages 594-599, DOI: 10.11646/zootaxa.4092.4.9, http://zenodo.org/record/265685

Tail tapering to a point (TaL/SVL 1.42); four postcloacal tubercles laterally; subcaudals distinctly enlarged. Coloration in life. Ground color of dorsal head, back, limbs, and tail yellowish brown; dorsal head with small spread spots and a heart-shaped marking on postocciput; nuchal loop present, in U-shape, from posterior corner of nare crossing eye and tympanum, extending to nape, dark brown, bolder from postocular to nape, irregularly edged in yellow; four greyish brown body bands between limb insertions with indentations in mid-dorsal region, edged in yellow; dorsal surface of fore and hind limbs with grey reticulations; tail with narrow light bands; ventral surface greyish cream. Sexual dimorphism. The single adult female differs from two adult males by its larger size (maximum SVL 89.3 mm versus 75.8 mm in the males) and lacking of hemipenial swellings at the base of tail (see Table 4 & Fig. 6). Comparisons. We compared Cyrtodactylus calamei sp. nov. with other Cyrtodactylus species known from Laos and neighbouring countries in the mainland Indochina region, including Vietnam, Cambodia, and Thailand based on examination of specimens (see Appendix) and data provided from taxonomic publications (Luu et al. 2014 a; Nazarov et al. 2014; Nguyen et al. 2014; Panitvong et al. 2014; Pauwels et al. 2014; Pauwels & Sumontha 2014; Schneider et al. 2014; Sumontha et al. 2015; Nguyen et al. 2015; Luu et al. 2015 a; Luu et al. 2016 a, b) (see Table 3). The cluster and correspondence analyses indicated that Cyrtodactylus calamei sp. nov. is nested in the same clade with C. darevskii and the species to be described in the following (Figs. 2���3). Molecular phylogenetic analyses also strongly supported the sister relationship between the new species and afore mentioned taxa (see Fig. 1). Morphologically, Cyrtodactylus calamei sp. nov. closely resembles the other karst forest species, C. darevskii and C. phongnhakebangensis, in dorsal colour pattern. However, the new species can be distinguished from C. darevskii by its smaller size (maximum SVL 89.3 mm versus 100 mm), having fewer dorsal tubercle rows (10���16 versus 16���20), fewer femoral and precloacal pores in males (35���39 versus 38���44), more femoral and precloacal pores in females (38 versus 24���34), the presence of heart-shaped marking on postocciput (versus absent), four greyish brown regular transverse body bands as wide as nearly two times of nuchal band (versus four to five dark irregular transverse breaking bands as narrow as nuchal band), first body band wide, butterfly-shaped (versus thin, U-shaped in C. darevskii), tail with light rings (versus banded); from C. phongnhakebangensis by its smaller size (maximum SVL 89.3 mm versus 96.3 mm), more scale rows from mental to the front of cloacal slit (183���197 versus 161���177), nuchal loop narrow, indented, not posteriorly enlarged (versus wide, posteriorly enlarged), four greyish brown transverse body bands, slightly narrower light bands (versus three to five dark transverse body bands, twice wider than light bands), and tail with light rings (versus bands) (see Table 4). Distribution. Cyrtodactylus calamei is currently known only from the type locality in Tham Nok En area, Hin Nam No NPA, Khammouane Province, central Laos (Fig. 6). Etymology. The new species is named in honour of our friend and colleague, Mr. Thomas Calame, from WWF Greater Mekong, Vientiane, Laos, who participated in our field research in Hin Nam No NPA, Khammouane Province between 2014 and 2015. As common names, we suggest Calame���s Bent-toed Gecko (English), Ki Chiem Calame (Laotian). Natural history. Specimens were found at night between 19: 30 and 21:08h, on limestone outcrops, at elevations between 190 and 260 m a.s.l. The surrounding habitat was karst forest. The relative humidity was 80 % and the air temperature ranged from 23 to 26 o C (see Table 5)., Published as part of Luu, Vinh Quang, Bonkowski, Michael, Nguyen, Truong Quang, Le, Minh Duc, Schneider, Nicole, Ngo, Hanh Thi & Ziegler, Thomas, 2016, Evolution in karst massifs: Cryptic diversity among bent-toed geckos along the Truong Son Range with descriptions of three new species and one new country record from Laos, pp. 101-140 in Zootaxa 4107 (2) on pages 113-117, DOI: 10.11646/zootaxa.4107.2.1, http://zenodo.org/record/266526, {"references":["Luu, V.

Cyrtodactylus species groups in Laos As currently recognized, 21 Cyrtodactylus species are known from Laos. Based on our molecular phylogeny, the molecular data presented in Nazarov et al. (2014), and a combination of characters including size, dorsal color pattern, scalation, and geographic distribution, we herein propose four species groups within the genus Cyrtodactylus occurring in Laos (see Table 13), which are defined as follows, Published as part of Luu, Vinh Quang, Bonkowski, Michael, Nguyen, Truong Quang, Le, Minh Duc, Schneider, Nicole, Ngo, Hanh Thi & Ziegler, Thomas, 2016, Evolution in karst massifs: Cryptic diversity among bent-toed geckos along the Truong Son Range with descriptions of three new species and one new country record from Laos, pp. 101-140 in Zootaxa 4107 (2) on page 132, DOI: 10.11646/zootaxa.4107.2.1, http://zenodo.org/record/266526, {"references":["Nazarov, R.

Ground color of dorsal head and back greyish brown; head without dark blotches; nuchal loop present, narrow, in U-shape, not enlarged posteriorly, extending from posterior corner of eye through tympanum to the neck, dark brown, edged in yellow posteriorly; four dark brown body bands between limb insertions, edged in yellow; dorsal surface of fore and hind limbs with greyish-brown dark spots; tail dorsally brown with 12 yellow-whitish rings, edged in yellow; ventral surface bright beige. Variation. The nuchal loop in the adult female paratype (ZFMK 97197) is interrupted in the middle. Other paratypes have some indistinct spot markings on dorsal head and somewhat irregular and breaking transverse bands. Sexual dimorphism. The females differ from the males by having fewer precloacal-femoral pores (17���21 versus 20���26 in the males) and females lack hemipenial swellings at the tail base (see Table 9). Comparisons. We compared the new species with its congeners from Laos and neighbouring countries in the mainland Indochina region, including Vietnam, Cambodia, and Thailand based on data obtained from the literature (compiled after Luu et al. 2014 a; Nazarov et al. 2014; Nguyen et al. 2014; Panitvong et al. 2014; Pauwels et al. 2014; Pauwels & Sumontha 2014; Schneider et al. 2014; Sumontha et al. 2015; Nguyen et al. 2015; Luu et al. 2015 a; Luu et al. 2016 a, b) and based on the examination of specimens and photographs (see Appendix and Table 3). Cyrtodactylus sommerladi sp. nov. was well separated by the cluster and correspondence analyses from C. roesleri (Figs. 2���3). Molecular phylogenetic analyses also revealed the close relationships between these species (see Fig. 1). The new species is most similar to C. roesleri from Vietnam in body size, and dorsal pattern. However, the new species can be distinguished from the latter by its larger size (maximal SVL 80.3 mm versus 73.5 mm), having more dark body bands: 5 or 6 (n= 15) versus 4���5 (n= 19), dorsal surface of the new species shows homogenous scales, all appear tubercle-like, with unclear dorsal tubercles (0���5) (versus dorsal tubercles being arranged in 13���19 rows) (Fig. 11), dorsal surface of tail without tubercles (versus present) (see Fig. 12 A,B) and the shape of the rostral suture in the new species is just straight vertical versus Y-shaped in C. roesleri. In addition, Cyrtodactylus sommerladi sp. nov. can be distinguished from C. roesleri by the different head shape, the head of the new species is wider and flatter (Fig. 5). Distribution. Currently, Cyrtodactylus sommerladi sp. nov. is known only from the type locality in the karst forest of Hin Nam No NPA, Khammouane Province, central Laos (Fig. 6). Etymology. The specific epithet sommerladi refers to our colleague and good friend Ralf Sommerlad, late Regional vice chairman of the IUCN SSC Crocodile Specialist Group (CSG) for Europe, who passed away on 11 June 2015, to honor his lifework and strong commitment for reptile conservation. As common names, we suggest Sommerlad���s Bent-toed Gecko (English), Ki Chiem Sommerlad (Laotian). Natural history. Specimens were collected at night from 19: 20 to 21: 43 h, mainly on karst walls, ca. 1���4.5 m above the ground, near cave entrances in the limestone forest, at elevations between 269 and 614 m a.s.l. Two female specimens IEBR A. 2015.38 and ZFMK 97197 were found on tree trunks, about 1���2 m from the forest floor. The surrounding habitat was karst forest dominated by species of Ebenaceae, Dracaenaceae, Arecaeae, Poaceae, Meliaceae, and Moraceae. The relative humidity was between 74 % and 90 %, and temperatures ranged from 22.7 to 29.9 o C (see Table 10). Female specimens contained eggs in May, by contrast, no records of gravid females or hatchlings were made in March. Thus, the breeding season seems to start only in April or May. The majority of the caves, karst walls, and karst forests where Cyrtodactylus sommerladi sp. nov. have been explored had dry surfaces, without flowing streams inside (e.g., Ellis & Pauwels 2012)., Published as part of Luu, Vinh Quang, Bonkowski, Michael, Nguyen, Truong Quang, Le, Minh Duc, Schneider, Nicole, Ngo, Hanh Thi & Ziegler, Thomas, 2016, Evolution in karst massifs: Cryptic diversity among bent-toed geckos along the Truong Son Range with descriptions of three new species and one new country record from Laos, pp. 101-140 in Zootaxa 4107 (2) on pages 123-128, DOI: 10.11646/zootaxa.4107.2.1, http://zenodo.org/record/266526, {"references":["Luu, V.

Cyrtodactylus hinnamnoensis sp. nov. is characterized by: Adult SVL 84.1 �� 11.7 mm (mean �� SD); dorsal head with dark blotches; nuchal loop wide, distinct, posteriorly enlarged; dorsal body with four to six blackish brown bands between limb insertions; 13���19 irregular, weakly keeled dorsal tubercle rows; 35���48 ventral scale rows; ventral scale rows from mental to cloacal slit 179���201; scale rows at midbody 93���112; ventrolateral folds present, without tubercles; 36���44 precloacal-femoral pores in the males; 0���28 pores in females; enlarged femoral and precloacal scales present; 4���6 postcloacal tubercles; subcaudals enlarged. Description of holotype. Adult male, snout-vent length (SVL) 83.6 mm; body elongate (TrunkL/SVL 0.42); head elongate (HL/SVL 0.27), relatively wide (HW/HL 0.68), depressed (HH/HL 0.40), distinguished from neck; loreal region concave; snout long (SE/HL 0.43), obtuse, longer than diameter of orbit (OD/SE 0.60); snout scales small, homogeneous, granular, larger than those on frontal and parietal regions; eye large (OD/HL 0.26), pupils vertical; eyelid fringe with tiny spines posteriorly; ear oval-shaped, small (EarL/HL 0.08); rostral wider than high (RH/RW 0.60), with a median suture; supranasals in contact anteriorly and separated from each other by a small scale posteriorly; rostral in contact with first supralabial and nostril scales on each side; nares oval, surrounded by supranasal, rostral, first supralabial, and two enlarged postnasals; mental triangular, wider than high (ML/MW 0.65); two enlarged postmentals in broad contact posteriorly, bordered by mental anteriorly, first two infralabials laterally, and eight small scales posteriorly; supralabials 12 / 10; infralabials 10 / 9. Dorsal scales granular to flattened; dorsal tubercles round, weakly keeled, present on occiput, back and tail base, each surrounded by 8 granular scales, in 15 irregular longitudinal rows at midbody; ventral scales smooth, medial scales 2���3 times larger than dorsal scales, round, subimbricate, largest posteriorly, in 35 longitudinal rows between lateral folds at midbody; ventrolateral folds present, without tubercles; gular region with homogeneous smooth scales; ventral scales in a line from mental to cloacal slit 186; precloacal groove absent; enlarged femoral scales present; femoral and precloacal pores 42. Fore and hind limbs moderately slender (ForeL/SVL 0.17, CrusL/SVL 0.21); dorsal fore limbs with slightly developed tubercles; dorsal hind limbs covered by distinctly developed tubercles; fingers and toes free of webbing; lamellae under fourth fingers 19 / 19, under fourth toes 20 / 20. Tail regenerated, postcloacal tubercles 5 / 5; dorsal tail bearing tubercles at base; subcaudals distinctly enlarged, flat, smooth. Coloration in life. Ground coloration of dorsal head greyish brown with dark blotches; nuchal loop black, in U-shape, from posterior corner of eye through tympanum to the neck, dark brown, edged in yellow; body bands between limb insertions five, somewhat irregular, dark brown, edged in white; dorsal surface of fore and hind limbs with dark bars; tail brown dorsally with light brown rings, edged by yellowish white; chin, throat, and belly cream; upper and lower lips with dark brown bars; tail ventrally grey with light dots. Sexual dimorphism. The females differ from the males by lacking or having fewer precloacal-femoral pores (0���28 versus 36���44 in the males) and the absence of hemipenial swellings at the tail base (see Table 6). Comparisons. We compared the new species with its congeners from Laos and neighbouring countries in the mainland Indochina region, including Vietnam, Cambodia, and Thailand based on examination of specimens (see Appendix) and data integrated from the literature (compiled after Luu et al. 2014 a; Nazarov et al. 2014; Nguyen et al. 2014; Panitvong et al. 2014; Pauwels et al. 2014; Pauwels & Sumontha 2014; Schneider et al. 2014; Sumontha et al. 2015; Nguyen et al. 2015; Luu et al. 2015 a; Luu et al. 2016 a, b) (see Tables 3). The cluster and correspondence analyses of morphological characters supported Cyrtodactylus hinnamnoensis sp. nov. as a sister taxon to C. darevskii (Figs. 2���3). Molecular phylogenetic analyses also demonstrated the close relationships between these species (see Fig. 1). Morphologically, Cyrtodactylus hinnamnoensis sp. nov. is closely related to the C. phongnhakebangensis group including C. darevskii, C. phongnhakebangensis, C. calamei by dorsal colour pattern and the number of cloacal and femoral pores in males. However, the new species can be distinguished from C. darevskii by having fewer cloacal and femoral pores in females (maximum 0���28 versus 24���34), four to six blackish brown transverse body bands, as wide as light bands (versus four to five dark irregular transverse breaking body bands, 0.5 times narrower than light band), first body band wide, butterfly-shaped (versus thin, U-shaped in C. darevskii), the presence of tubercles on fore limbs (versus absent), and tail consisting of light rings (versus banded); Cyrtodactylus hinnamnoensis sp. nov. differs from C. phongnhakebangensis by its slightly larger size (SVL reaching 100.6 mm versus 96.3 mm), having fewer cloacal and femoral pores in females (0���28 versus 0���41), having more scale rows from mental to the front of cloacal slit (179���201 versus 161���177), the presence of tubercles on fore limbs (versus absent), a narrower nuchal loop, not enlarged posteriorly (wide, enlarged posteriorly), four to six blackish brown transverse body bands as wide as light bands (versus three to five dark transverse body bands as wide as double light bands, light transverse bands with small spots (versus with big black blotches), and tail pattern consisting of light rings (versus banded); Cyrtodactylus hinnamnoensis sp. nov. differs from C. calamei by its larger size (SVL reaching 100.6 mm versus 89.3 mm), fewer cloacal and femoral pores in females (0���28 versus 38), more postcloacal tubercles (4���6 versus 4), dorsal head marking with distinctly dark spots and blotches (versus indistinct dots), the absence of heart-shaped marking on postocciput (versus present), four to six blackish brown body = standard deviati��n, f��r ��ther abbreviati��ns see material and meth��ds). ������continued on the next page transverse bands, as wide as light bands (versus four greyish brown transverse bands, narrower than light bands) (for more details see Table 7, Fig. 9). The results of the correspondence analysis comparing all adult male morphological maesurements of Cyrtodactylus hinnamnoensis sp. nov. and the latter species indicated four distinct groups between these species (see Fig. 4). Distribution. Cyrtodactylus hinnamnoensis sp. nov. is currently known only from the type locality in the karst forest of Hin Nam No NPA, Khammouane Province, central Laos (Fig. 6). Etymology. We name this species after its type locality, Hin Nam No NPA where the new Cyrtodactylus species was discovered and propose the following common names: Hinnamno Bent-toed Gecko (English), Ki Chiem Hin Nam No (Laotian). Natural history. Specimens were found at night between 19: 41 and 22:03h on karst walls, ca. 0.3���5 m above the ground, near cave entrances in the limestone forest, at elevations between 175 and 580 m a.s.l. Only one male specimen VNUF R. 2014.99 was collected on a tree trunk, about 1 m from the forest floor. The surrounding habitat was karst forest, dominated by species of Ebenaceae, Dracaenaceae, Arecaeae, Poaceae, Meliaceae, and Moraceae. The relative humidity ranged from 78 % to 90 %, and temperatures were from 24.9 to 30.7 o C (see Table 8). When capturing individuals of the species, we observed an increased rate of tail autotomy and many individuals had regenerated tail, for example, seven of 11 specimens of Cyrtodactylus hinnamnoensis sp. nov. had dropped or/and regenerated tails. This suggests that these populations might be under the stress of predators (see also Grismer et al. 2016)., Published as part of Luu, Vinh Quang, Bonkowski, Michael, Nguyen, Truong Quang, Le, Minh Duc, Schneider, Nicole, Ngo, Hanh Thi & Ziegler, Thomas, 2016, Evolution in karst massifs: Cryptic diversity among bent-toed geckos along the Truong Son Range with descriptions of three new species and one new country record from Laos, pp. 101-140 in Zootaxa 4107 (2) on pages 117-123, DOI: 10.11646/zootaxa.4107.2.1, http://zenodo.org/record/266526, {"references":["Luu, V.

Description Adult Moderately slender to slender nematodes of medium to big size, 2.56���3.24 mm long. Body cylindrical, distinctly tapering towards the anterior end, less so towards the posterior end as the caudal region is short and rounded. Habitus curved ventrad after fixation, especially in posterior body region, C-, G- or spiral-shaped. Cuticle 3.0���4.5 ��m thick at anterior region, 5���6 ��m in mid-body and 8���10 ��m on tail; consisting of three layers, especially distinguishable at caudal region: thinner outer layer bearing very fine transverse striation across the entire body, thicker intermediate layer with radial striation, and thin inner layer. Lateral chords 13���21 ��m wide at mid-body, occupying about one-sixth (13���18%) of midbody diameter. Two ventral and two dorsal body pores often present at level of odontostyle-odontophore. Lip region hardly offset from the adjacent body by weak, but perceptible depression, 2.8���3.0 times wider than high and up to one-fourth (17���25%) of body diameter at neck base; lips (under SEM) mostly amalgamated, but their perioral part distinctly separated by the existence of six radial, interlabial, deep incisures delimiting six perceptible liplets; button-like labial papillae, the inner ones located at the margin of the oral field and surrounded by two or three concentric annuli, whereas the outer papillae, located a little behind the inner papillae, are surrounded by only one annulus; cephalic papillae pore- rather than button-like, also surrounded by only one ring-like annulus; oral aperture a dorso-ventral, slightly hexagonal orifice, the lip region hence showing a bi-radial symmetry. Amphid fovea cup-shaped, its opening occupying 9���10 ��m or less than one-half (43���49%) of lip region diameter. Cheilostom nearly cylindrical, without any differentiation. Stomatal protruding structure apparently a reduced odontostyle 6.6���7.1 times longer than wide (see: Remarks), its ventral side 1.0���1.1 times longer than lip region diameter and 0.65���0.83% of body length. Guiding ring simple, plicate, at 0.8���0.9 lip region diameters from the anterior end. Odontophore linear, rod-like, 1.7���1.9 times the odontostyle length, somewhat irregular at its base and with (in lateral view) the ventral side slightly longer than the dorsal one (Fig. 2A). Anterior region of pharynx enlarging very gradually; basal expansion 7.1���10.7 times longer than wide, 3.6���5.6 times as long as body diameter, and occupying 52���59% of total neck length; gland nuclei often obscure, located as follows: DN = 60���62 (n = 4); S 1 N 1 = 75 (n = 2); S 1 N 2 = obscure; S 2 N = obscure. Nerve ring located at 182���216 ��m from anterior end or 25���26% of total neck length. Cardia rounded conoid, 13���17 �� 13���17 ��m; a weak ring-like structure is present surrounding its junction to pharyngeal base. Female Genital system didelphic-amphidelphic, with almost equally and well developed branches, the anterior 320���442 ��m or 12���15% of body length and the posterior 348, 440 ��m (n = 2) or 14, 16% of body length (447, 509 ��m or 15, 17% bearing one uterine egg inside). Reflexed ovaries well developed, often surpassing the sphincter level, the anterior 182���319 ��m, the posterior 207���380 ��m long; oocytes arranged first in two or more rows, then in a single row. Oviduct 124���174 ��m long or 1.1���1.8 times the corresponding body diameter, and consisting of a slender part made of prismatic cells and a moderately developed pars dilatata, with visible lumen and often containing sperm cells inside. Oviduct-uterus junction marked by a sphincter. Uterus a simple, tube-like structure 150���190 ��m long or 1.2���1.7 times the corresponding body diameter [223, 242 ��m (n = 2) long or 2.2, 2.5 times the corresponding body diameter, with one uterine egg inside; and 231, 240 ��m (n = 1) long, with two uterine eggs], always containing abundant sperm cells inside. Vagina extending inwards 52���57 ��m or one-half to foursevenths (48���57%) of body diameter: pars proximalis 33���43 �� 23���28 ��m, with somewhat sigmoid walls surrounded by weak musculature; pars refringens with two trapezoidal pieces measuring (in optical section) 13���16 �� 7���9 ��m and with a combined width of 24���28 ��m; pars distalis 5.5���7.0 ��m long. Vulva a nearly equatorial transverse slit. Prerectum 2.0���2.4, rectum 0.7���1.0 anal body diameters long. Tail short and rounded; two pairs of caudal pores, sublateral and close together. Male Genital system diorchic, with opposite testes. In addition to the ad-cloacal pair, situated at 18���21 ��m from cloacal aperture, one weakly developed ventromedian supplement, lying out the range of retracted spicules and located at 80���131 ��m from the ad-cloacal pair. Spicules distinctly robust and massive, especially in its posterior half, 3.6���4.2 times its maximum width, 1.4���1.6 times the body diameter at level of the cloacal aperture: dorsal contour regularly convex, ventral contour slightly concave, with distinct hump and hollow; curvature 121���124��; head occupying 11���16% of spicule total length, its dorsal side visibly curved at its anterior end and longer than the ventral one, which is shorter and almost straight; median piece 5.4���6.2 times longer than wide, occupying 51���59% of spicule maximum width, reaching the posterior tip; posterior end 7���8 ��m wide. Lateral guiding pieces 23���29 ��m long, 5.3��� 7.1 times longer than wide. Prerectum 3.2���4.6, cloaca 0.9���1.3 times the corresponding body width long. Cloacal aperture, as seen under SEM, a curved anteriad, transverse slit. Tail similar to that of female; caudal pores two pairs, one lateral, another subdorsal. Relationships In having a long stomatal protruding structure (20���21 ��m at its ventral side) and short (c��� up to 1.0) and rounded tail, S. tropicum sp. nov. is morphologically very similar to S. demani Altherr, 1965, S. heynsi Altherr, 1968, S. rotundicauda Goodey, 1951, S. septentrionale Pe��a-Santiago & ��lvarez-Ortega, 2015 and S. sica Clark, 1964, but it can be distinguished from all of them in its smaller general size (body length 2.56���3.24 mm, neck 730���834 ��m long vs more than 5 mm, more than 1000 ��m long, respectively), nearly continuous lip region (vs offset by a more or less deep constriction) and stomatal protruding structure of different nature (a reduced odontostyle vs a mural tooth; see Remarks). Besides, the new species differs from S. demani (see recent re-description by Pe��a-Santiago & ��lvarez-Ortega 2014b) in its less slender (a = 21���36 vs a = 48���56) body, narrower (19���21 vs 27���28 ��m broad) lip region, shorter pharyngeal expansion (occupying 52���59 vs 68���69% of total neck length), shorter female tail (32���39 vs 51���55 ��m, c��� = 0.5���0.6 vs c��� = 0.7���0.8), and male present (vs absent). It differs from S. heynsi (see recent re-description by Pe��a-Santiago & ��lvarez-Ortega 2014b) in its narrower (19���21 vs 28 ��m broad) lip region, circumoral area lacking (vs bearing) cilia- or setae-like structures, shorter pharyngeal expansion (occupying 52���59 vs 68% of total neck length), shorter (32���39 vs 54 ��m, c��� = 0.5���0.6 vs c��� = 0.7) female tail, and male present (vs absent). It differs from S. rotundicauda in its less slender (a = 21���36 vs a = 80) body, narrower (19���21 vs about 28 ��m broad) lip region, shorter (31���40 vs 64 ��m) male tail, fewer (one vs four) ventromedian supplements, and shorter (91���97 vs about 155 ��m) spicules. It differs from S. septentrionale in its less slender (a = 21���36 vs a = 47���64) body, narrower (19���21 vs 25���29 ��m broad) lip region, shorter (occupying 52���59 vs 60���73% of total neck length) pharyngeal expansion, uterus simple (vs tripartite) and shorter (150���242 ��m or 1.2���2.5 times the body diameter vs 370���493 ��m or 2.9���4.3 times the corresponding body diameter), shorter (31���40 vs 40���62 ��m, c��� = 0.5���0.6 vs c��� = 0.6���0.8) tail, fewer (one vs 5���11) ventromedian supplements, and shorter (91���97 vs 100���145 ��m) spicules. Finally, it differs from S. sica in its narrower (19���21 vs about 24 ��m broad) lip region, shorter (occupying 52���59% vs two-thirds of total neck length) pharyngeal expansion, more posterior (V = 48���52 vs V = 40) vulva, shorter (32���39 vs 54 ��m, c��� = 0.5���0.6 vs c��� = 0.7) female tail, and male present (vs absent). Moreover, in having a lip region nearly continuous with the adjacent body, the new species resembles S. mucrodens Siddiqi, 1984 and S. truxum Siddiqi, 1984, but it can be easily distinguished from these by the more anterior position of the stomatal protruding structure (its anterior tip in front of the level of guiding ring, just behind the base of lip region vs its anterior tip distinctly behind the level of guiding ring, far from the lip region base) and pars refringens vaginae well (vs faintly) developed. Moreover, it differs from S. mucrodens by its shorter (730���834 vs 1086���1157 ��m) neck, shorter (occupying 52���59 vs 69% of total neck length) pharyngeal expansion, shorter (32���39 ��m, c��� = 0.5���0.6 vs 44���50 ��m, c��� = 0.7) female tail, and male present (vs absent). It differs from S. truxum in its narrower (19���21 vs 24 ��m broad) lip region, shorter (730���834 vs 837���1070 ��m) neck, more anterior (V = 48���52 vs V = 54���56) vulva, and male present (vs absent). Molecular characterisation Two sequences of the D2���D 3 28S rRNA gene were obtained from one female and one male. Both sequences are very similar (99%) and differ by two nucleotides only. The evolutionary relationships of the new species with representatives of the order Dorylaimida are presented in Figs 5���6. The two S. tropicum sp. nov. sequences are clustered together with other available sequences of Sectonema representatives and form a highly supported clade together with members of the genus Metaporcelaimus, thus confirming previous results (��lvarez-Ortega et al. 2013a, b). Remarks The nature of the stomatal protruding structure in the new species is difficult to interpret and deserves further explanation. The specimens examined bear a reduced odontostyle (comparable to that described in the type species S. ventrale Thone, 1930; see recent description by Pe��a-Santiago & ��lvarez-Ortega 2014a) rather than a mural tooth as the base of its dorsal side is visibly sclerotized and seems to join the dorsal stomatal wall (vs dorsal side not scletorized at the base, somewhat sigmoid and not joining the dorsal stomatal wall).

Etymology The specific epithet refers to the geographical origin of the species. Type material examined Holotype VIETNAM: ♀, in good state of preservation, Northern Vietnam, Cuc Phuong National Park, pristine tropical forest, deposited in the nematode collection of the University of Jaén, Spain. Paratypes VIETNAM: 4 ♁♁, 3 juvs, in good state of preservation, same data as holotype; 1 ♁, in good state of preservation, same locality, deposited in the nematode collection of the Institute of Ecology and Biological Resources, Hanoi, Vietnam; 1♁, 1 juv., same locality, used for SEM. Other material examined VIETNAM: 2 ♁♁, in acceptable state of preservation, Northern Vietnam, Thái Bình province, intensively cultured field, deposited in the nematode collection of the University of Jaén, Spain. Description (type population) Adult Very slender nematodes of big size, 3.13–4.25 mm long. Body cylindrical, distinctly tapering towards the anterior end, less so towards the posterior one as the caudal region is rounded. Habitus regularly curved ventrad after fixation, to a more or less open C, occasionally more curved at posterior body region. Cuticle 2.0–2.5 μm thick at anterior region, 3.0–4.5 μm in mid-body and 8–10 μm on tail; consisting of three layers especially distinguishable at caudal region: thinner outer layer bearing very fine transverse striation through the entire body, thicker intermediate layer with radial striation, and thin inner layer. Lateral chords 6–12 μm wide at mid-body, occupying up to one-sixth (8–15%) of mid-body diameter. Two ventral and two dorsal body pores often present at level of stoma, and four distinct lateral pores 6–20 μm apart visible behind the amphid fovea. Lip region nearly continuous (a shallow depression is, however, often perceptible), weakly angular, visibly narrower than adjacent body, 2.1–2.3 times wider than high and about one-fifth (18–23%) of body diameter at neck base; it appears (under SEM) marked by radial (oral field) or longitudinal (remaining lip region) incisures, with amalgamated lips and protruding, pore-like labial and cephalic papillae, all of them surrounded by a ring-like annulus, and the inner labial papillae visibly larger than the outer ones; oral field perceptibly hexagonal, oral aperture a dorso-ventral slit, the lip region hence showing a bi-radial symmetry. Cupshaped amphid fovea, its opening at level of cephalic depression and occupying 10–11 μm or 68–72% of lip region diameter. Nearly cylindrical cheilostom, without differentiation. Odontostyle comparatively short and occupying the whole stomatal lumen, its ventral side 0.5–0.6 times longer than lip region diameter and 0.20–0.29% of body length. Guiding ring simple, somewhat plicate, at 0.5 times the lip region diameter from anterior end. Odontophore linear, rod-like, 3.7–4.2 times the odontostyle length. Tripartite pharynx, consisting of an anteriorly thickened section behind the odontophore base, a perceptible narrower intermediate section with the nerve ring surrounding it, which enlarges very gradually into the basal expansion 9.9–15.0 times longer than wide, 6.7–7.3 times longer than body diameter and occupying 63–67% of total neck length; gland nuclei mostly obscure, only S 2 N are visible, at 77–78% (n = 3) of total neck length. Nerve ring located at 147–178 μm from anterior end or 19–22% of total neck length. Cardia rounded conoid, 15–19 × 12–17 μm; a ring-like structure is present surrounding its junction to pharyngeal base. Female Genital system didelphic-amphidelphic, with almost equally and well developed branches, the anterior 473 μm long or 13% of body length and the posterior 387 μm long or 10% of body length, each branch bearing one uterine egg. Moderately sized ovaries, not surpassing the sphincter level, the anterior 191 μm, the posterior 141 μm long; oocytes arranged first in two or more rows, then in a single row. Oviduct 117, 142 μm long or 1.4, 1.7 times the corresponding body diameter, and consisting of a slender part made of prismatic cells and a well developed pars dilatata with wide lumen and sperm cells inside. Oviduct-uterus junction marked by a sphincter. Uterus a simple, tube-like structure 209, 242 μm long or 2.5, 2.9 times the corresponding body diameter, containing abundant sperm cells and one uterine egg. Vagina extending inwards 36 μm or about three-sevenths (44%) of body diameter: pars proximalis 23 × 28 μm, somewhat sigmoid walls and surrounded by weak musculature; pars refringens absent; pars distalis well developed, 15 μm long. Vulva a post-equatorial transverse slit. Prerectum 3.0, rectum 0.9 anal body diameters long. Short and rounded tail, its inner core with a finger-like projection at tail end; two pairs of caudal pores, one sub-lateral, another sub-dorsal. Male Genital system diorchic, with opposite testes. In addition to the ad-cloacal pair, situated at 14–19 μm from cloacal aperture, there is a series of three or four irregularly spaced, 15–48 μm apart, ventromedian supplements, the posteriormost of which lying out the range of retracted spicules, at 76–91 μm from the ad-cloacal pair. Spicule robust and massive, especially in its posterior half, 3.6–4.6 times its maximum width, 1.3–1.4 times the body diameter at level of the cloacal aperture: dorsal contour regularly convex, ventral contour slightly concave, with distinct hump and hollow; curvature 125–136º; head occupying 13–19% of spicule total length, its dorsal contour distinct curved at its anterior end and longer than the ventral one, which is short and almost straight; median piece 5.9–7.1 times longer than wide, occupying 52–65% of spicule maximum width, reaching the posterior tip; posterior end 6–7 μm wide. Lateral guiding pieces 15–17 μm long, 5.3–6.5 times longer than wide. Prerectum 4.3–5.7, cloaca 1.0–1.3 times the corresponding body width long. Rectal glands and their ducts (cf. Coomans & Loof 1986) very well perceptible (Fig. 8K). Cloacal aperture, as seen under SEM, a somewhat curved anteriad, transverse slit; the two supplements of the precloacal pair distinctly separated. Tail a little more conoid than that of female; two pairs of caudal pores, one almost lateral, another sub-dorsal. Relationships The new species is easily distinguishable from its congeners in the unique combination of these features: narrow and nearly continuous lip region, very short odontostyle, absence of pars refringens vaginae and short and rounded tail. Nonetheless, it resembles S. barbatum Heyns, 1965 in its general morphology, but it can be distinguished from this because of its oral field lacking any setae-like structure (vs bearing numerous short forwardly pointing setae), narrower (14–16 vs about 22 μm broad) lip region, shorter (8–9 vs 16 μm) odontostyle, pars refringens vaginae absent (vs present), shorter (36 μm, c = 105, c’ = 0.7 vs 48 μm, c = 81, c’ = 1.0) female tail, and male present (vs absent). In having a comparatively small body size and nearly continuous lip region, S. vietnamense sp. nov. is close to S. mucrodens and S. truxum, from which it differs in its narrower (14–16 vs more than 20 μm broad) lip region, shorter stomatal protruding structure (8–9 vs more than 20 μm) located as usual (vs the anterior tip distinctly behind the level of guiding ring), and pars refringens vaginae absent (vs consisting of two small pieces). Sectonema vietnamense sp. nov. is also similar to S. pseudoventrale Heyns, 1965 in having a short odontostyle, but can be distinguished from this by its narrower (14–16 vs 21–23 μm broad) lip region, shorter (209–242 μm or 2.5–2.9 times the corresponding body diameter vs 123 μm or 1.3 times the corresponding body diameter) uterus, shorter (36 μm, c = 105, c’ = 0.7 vs 46–63 μm, c = 82–130, c’ = 0.8–1.0) female tail, shorter (59– 75 vs 90–95 μm) spicules, and fewer (three or four vs six or seven) ventromedian supplements. Finally, the new species also resembles S. tropicum sp. nov., but it can be distinguished from this by its narrower (14–16 vs 19–21 μm broad) lip region, shorter (8–9 vs 20–21 μm at its ventral side) odontostyle, longer (occupying 63–67 vs 52–59% of total neck length) pharyngeal expansion, more posterior vulva (V = 54 vs V =48–52), pars refringens vaginae absent (vs present), shorter (59–75 vs 91–97 μm) spicules and higher number of ventromedian supplements (three or four vs one). Remarks The two males from Thái Bình are very similar to those of the type population, but some minor morphometric differences have been also noted: somewhat smaller (2.71, 3.02 vs 3.13–4.25 mm long) and more obese (a = 33, 35 vs a = 41–49) body. Such differences have been regarded as instraspecific variation as the number of specimens examined is low and the main morphological and morphometric features are coincident.

Relationships In having a long stomatal protruding structure (20–21 μm at its ventral side) and short (c’ up to 1.0) and rounded tail, S. tropicum sp. nov. is morphologically very similar to S. demani Altherr, 1965, S. heynsi Altherr, 1968, S. rotundicauda Goodey, 1951, S. septentrionale Peña-Santiago & Álvarez-Ortega, 2015 and S. sica Clark, 1964, but it can be distinguished from all of them in its smaller general size (body length 2.56–3.24 mm, neck 730–834 μm long vs more than 5 mm, more than 1000 μm long, respectively), nearly continuous lip region (vs offset by a more or less deep constriction) and stomatal protruding structure of different nature (a reduced odontostyle vs a mural tooth; see Remarks). Besides, the new species differs from S. demani (see recent re-description by Peña-Santiago & Álvarez-Ortega 2014b) in its less slender (a = 21–36 vs a = 48–56) body, narrower (19–21 vs 27–28 μm broad) lip region, shorter pharyngeal expansion (occupying 52–59 vs 68–69% of total neck length), shorter female tail (32–39 vs 51–55 μm, c’ = 0.5–0.6 vs c’ = 0.7–0.8), and male present (vs absent). It differs from S. heynsi (see recent re-description by Peña-Santiago & Álvarez-Ortega 2014b) in its narrower (19–21 vs 28 μm broad) lip region, circumoral area lacking (vs bearing) cilia- or setae-like structures, shorter pharyngeal expansion (occupying 52–59 vs 68% of total neck length), shorter (32–39 vs 54 μm, c’ = 0.5–0.6 vs c’ = 0.7) female tail, and male present (vs absent). It differs from S. rotundicauda in its less slender (a = 21–36 vs a = 80) body, narrower (19–21 vs about 28 μm broad) lip region, shorter (31–40 vs 64 μm) male tail, fewer (one vs four) ventromedian supplements, and shorter (91–97 vs about 155 μm) spicules. It differs from S. septentrionale in its less slender (a = 21–36 vs a = 47–64) body, narrower (19–21 vs 25–29 μm broad) lip region, shorter (occupying 52–59 vs 60–73% of total neck length) pharyngeal expansion, uterus simple (vs tripartite) and shorter (150–242 μm or 1.2–2.5 times the body diameter vs 370–493 μm or 2.9–4.3 times the corresponding body diameter), shorter (31–40 vs 40–62 μm, c’ = 0.5–0.6 vs c’ = 0.6–0.8) tail, fewer (one vs 5–11) ventromedian supplements, and shorter (91–97 vs 100–145 μm) spicules. Finally, it differs from S. sica in its narrower (19–21 vs about 24 μm broad) lip region, shorter (occupying 52–59% vs two-thirds of total neck length) pharyngeal expansion, more posterior (V = 48–52 vs V = 40) vulva, shorter (32–39 vs 54 μm, c’ = 0.5–0.6 vs c’ = 0.7) female tail, and male present (vs absent). Moreover, in having a lip region nearly continuous with the adjacent body, the new species resembles S. mucrodens Siddiqi, 1984 and S. truxum Siddiqi, 1984, but it can be easily distinguished from these by the more anterior position of the stomatal protruding structure (its anterior tip in front of the level of guiding ring, just behind the base of lip region vs its anterior tip distinctly behind the level of guiding ring, far from the lip region base) and pars refringens vaginae well (vs faintly) developed. Moreover, it differs from S. mucrodens by its shorter (730–834 vs 1086–1157 μm) neck, shorter (occupying 52–59 vs 69% of total neck length) pharyngeal expansion, shorter (32–39 μm, c’ = 0.5–0.6 vs 44–50 μm, c’ = 0.7) female tail, and male present (vs absent). It differs from S. truxum in its narrower (19–21 vs 24 μm broad) lip region, shorter (730–834 vs 837–1070 μm) neck, more anterior (V = 48–52 vs V = 54–56) vulva, and male present (vs absent). Molecular characterisation Two sequences of the D2–D 3 28S rRNA gene were obtained from one female and one male. Both sequences are very similar (99%) and differ by two nucleotides only. The evolutionary relationships of the new species with representatives of the order Dorylaimida are presented in Figs 5–6. The two S. tropicum sp. nov. sequences are clustered together with other available sequences of Sectonema representatives and form a highly supported clade together with members of the genus Metaporcelaimus, thus confirming previous results (Álvarez-Ortega et al. 2013a, b). Remarks The nature of the stomatal protruding structure in the new species is difficult to interpret and deserves further explanation. The specimens examined bear a reduced odontostyle (comparable to that described in the type species S. ventrale Thone, 1930; see recent description by Peña-Santiago & Álvarez-Ortega 2014a) rather than a mural tooth as the base of its dorsal side is visibly sclerotized and seems to join the dorsal stomatal wall (vs dorsal side not scletorized at the base, somewhat sigmoid and not joining the dorsal stomatal wall). Nonetheless, some doubt persists in this matter.

Sexual dimorphism. The female differs from the males by the absence of femoral and precloacal pores (versus 29 pores in males) and the absence of hemipenial swellings at the tail base (see Tables 1 & 2). Comparisons. In the following we compare the new species with its congeners from Laos and neighbouring countries from the mainland Indochina region, including Vietnam, Cambodia, and Thailand based on examination of specimens (see Appendix) and data obtained from the literature (Luu et al. 2014; Nazarov et al. 2014; Nguyen et al. 2014; Panitvong et al. 2014; Pauwels et al. 2014; Pauwels & Sumontha 2014; Schneider et al. 2014; Sumontha et al. 2015) (see Table 3). Morphologically, Cyrtodactylus soudthichaki sp. nov. closely resembles C. jaegeri Luu, Calame, Bonkowski, Nguyen & Ziegler and C. roesleri Ziegler, Nazarov, Orlov, Nguyen, Vu, Dang, Dinh & Schmitz in overall coloration and pattern. However, the new species can be distinguished from C. jaegeri by having fewer femoral and precloacal pores in males (29 versus 44 in C. jaegeri), more dorsal tubercle rows on body (19–20 versus 15–17 in C. jaegeri) and the absence of femoral and precloacal pores in the female (present in C. jaegeri), and from C. roesleri by having transverse dorsal bands between limb insertions with indentations in the posterior part of dorsal bands at the vertebral region (versus without indentations in C. roesleri) (see Ziegler et al. 2010), fewer ventral scale rows (32–33 versus 34–40 in C. roesleri), more femoral and precloacal pores in males (29 versus 20–28 in C. roesleri), and the absence of femoral pores in the female (present in C. roesleri).

Distribution. Cyrtodactylus soudthichaki sp. nov. is currently known only from the type locality in Khun Don Mountain, Phou Hin Poun NPA, Khammouane Province, central Laos (Fig. 5). Etymology. This species is named in honour of Mr. Sisomphone Soudthichak, from the Natural Resources and Environment Department of Khammouane Province, Laos, who provided great support for our field research in Laos since 2013. As common names, we suggest Soudthichak’s Bent-toed Gecko (English) and Soudthichak’s Ki Chiem (Laotian). Natural history. The specimens were found between 19:00 and 21:00, on the branches of shrubs and karst boulders in a karst forest, approximately 0.3 m above the forest floor, between 150 and 170 m a.s.l. The karst forest included species of the dominated families Ebenaceae, Dracaenaceae, Arecaeae, Poaceae, Meliaceae, and Moraceae. The humidity at the time of collection was approximately 85 % and the air temperature ranged from 23 to 26 o C.

Distribution. Cyrtodactylus soudthichaki sp. nov. is currently known only from the type locality in Khun Don Mountain, Phou Hin Poun NPA, Khammouane Province, central Laos (Fig. 5). Etymology. This species is named in honour of Mr. Sisomphone Soudthichak, from the Natural Resources and Environment Department of Khammouane Province, Laos, who provided great support for our field research in Laos since 2013. As common names, we suggest Soudthichak���s Bent-toed Gecko (English) and Soudthichak���s Ki Chiem (Laotian). Natural history. The specimens were found between 19:00 and 21:00, on the branches of shrubs and karst boulders in a karst forest, approximately 0.3 m above the forest floor, between 150 and 170 m a.s.l. The karst forest included species of the dominated families Ebenaceae, Dracaenaceae, Arecaeae, Poaceae, Meliaceae, and Moraceae. The humidity at the time of collection was approximately 85 % and the air temperature ranged from 23 to 26 o C., Published as part of Luu, Vinh Quang, Calame, Thomas, Nguyen, Truong Quang, Bonkowski, Michael & Ziegler, Thomas, 2015, A new species of Cyrtodactylus (Squamata: Gekkonidae) from the limestone forest of Khammouane Province, central Laos, pp. 388-402 in Zootaxa 4058 (3) on pages 389-399, DOI: 10.11646/zootaxa.4058.3.6, http://zenodo.org/record/240248, {"references":["Luu, Q.

Scalation of the type series of Hemiphyllodactylus kiziriani sp. nov. from Luang Prabang Province, Laos. Etymology. We name the new species in honour of Dr. David A. Kizirian, American Museum of Natural History (New York, USA), in recognition of his contribution to herpetological research in the Indochina region. As common names we suggest Kizirian���s Slender Gecko (English), Kizirians Halbblattfingergecko (German), and Th���ch s��ng d���p ki-zi-ri-an (Vietnamese). Natural history. Hemiphyllodactylus kiziriani inhabits disturbed secondary limestone forests near a residential area at elevations between 590 and 640 m. Specimens were found at night on tree bark and limestone cliffs near cave entrances or on a limestone boulder near a forest path, ca. 0.2���1.2 m above the ground. Two female paratypes (IEBR A. 2014.5, NUOL R- 2014.2) were gravid with two shelled eggs each. Distribution. The species is currently known only from Luang Prabang Province in northern Laos (Fig. 4)., Published as part of Nguyen, Truong Quang, Botov, Andreas, Le, Minh Duc, Nophaseud, Liphone, Zug, George, Bonkowski, Michael & Ziegler, Thomas, 2014, A new species of Hemiphyllodactylus (Reptilia: Gekkonidae) from northern Laos, pp. 45-56 in Zootaxa 3827 (1) on pages 48-55, DOI: 10.11646/zootaxa.3827.1.4, http://zenodo.org/record/286482
