The Solomon Islands host a diverse terrestrial vertebrate fauna which has played a formative role in the development of speciation theory. Yet, despite over a century of biological exploration in the region, there are many islands for which we have incomplete knowledge of the vertebrate fauna. In 2019, we spent 20 days on Tetepare Island in the Western Province, Solomon Islands. Tetepare has a long history of conservation action by local communities and it is now the largest uninhabited tropical island in the world. We recorded 57 species of birds, 13 mammals, 5 amphibians, and 21 reptiles. Of these, we documented six species for the first time on Tetepare by western scientists: one frog, three non-avian reptiles, and two mammals. These findings point to a continued need for basic biological inventory work to inform research, local conservation efforts, and to increase published knowledge of the biodiversity in the Solomon Islands. Keywords: amphibians, birds, mammals, Melanesia, squamates, tropical South Pacific, Whitney South Sea Expedition, THE SOLOMON ARCHIPELAGO is a biodiverse region that is well known for its unique composition of terrestrial vertebrates (mammals, squamates, amphibians, and birds). Due in part to its high degree [...]

We describe a new species of fanged frog (genus Limnonectes) from the foothills of two, inland, south-to-north oriented, parallel mountain ranges of Luzon Island of the northern Philippines. Although the new species broadly co-occurs with its closest relative at numerous localities within the Luzon Pleistocene aggregate island complex faunal region, it can be readily diagnosed from Limnonectes macrocephalus based on its unpigmented (white) ventral surfaces of terminal digital discs, its unexpanded or minimally expanded terminal digital discs, and an allometric growth pattern indicating evidence of sexual dimorphism at a smaller overall body size. The new species, which can also be identified by its divergent 16S ribosomal RNA mitochondrial gene sequence, possesses a curious distribution unlike the range of any Philippine endemic amphibian characterized to date: it is known from nine interior (inland) localities distributed between the two, parallel, south-to-north mountain chains (the Cordillera and Sierra Madre) which characterize mainland Luzon. We interpret the presence of two broadly sympatric, genetically divergent, strongly supported haplotype clades—which correspond to morphologically diagnosable phenotypes, using traditional discrete characters and allometric growth patterns—as prima facia evidence of two, independently evolving evolutionary lineages (species) of giant fanged frogs on Luzon. The description of another new species of large-bodied fanged frog on Luzon from multiple localities in close proximity to the capital city (Manila) emphasizes the degree to which even well-studied larger Philippine landmasses possess unrecognized and overlooked biodiversity.

Diagnosis and comparisons.— Limnonectes beloncioi is a medium-sized fanged frog, assigned to the genus Limnonectes (family Dicroglossidae), on the basis of its prominent, sexually dimorphic odontoid processes characteristic of the genus among other osteological synapomorphies (Inger, 1954, 1966; Emerson and Berrigan, 1993). The new species can be distinguished from all other known congeners based on a combination of its single-pulse/note advertisement call (vs. dual-pulses/note in L. acanthi from Palawan Island faunal region and PAIC landmasses), its phylogenetic position (sister to L. acanthi from Palawan PAIC; Evans et al., 2003; Setiadi et al., 2011), and its geographic distribution on Mindoro and Semirara Islands (vs. Palawan PAIC); it is the only species of Limnonectes known to occur on Mindoro and Semirara Islands and associated small satellite islands and, therefore, has no sympatric congeners. The new species is morphologically similar to its closest relative, L. acanthi; however, it may be distinguished from this allopatric congener by its male advertisement call. The note pulse substructure of L. beloncioi is singular (1 pulse per note vs. 2 pulses per note in L. acanthi), and the new species has a slower note repetition rate (11.5–12.8 notes per second vs. 14.2–15.4 notes per second), and has a higher dominant frequency (2,067.2–2,799.3 Hz vs. 1,335.1–1,679.6 Hz in L. acanthi). With the exception of the morphologically indistinguishable L. acanthi, the new species can be distinguished from all other Philippine species of Limnonectes (L. diuatus, L. ferneri, L. leytensis, L. macrocephalus, L. magnus, L. micrixalus, L. palavanensis, L. parvus, L. visayanus, and L. woodworthi) by a combination of body size, fang (odontoid) length, snout shape, relative lengths of the first and second finger, dorsal skin rugosity, restriction of white-tipped dermal asperities to the sacral region (not aggregated in radial clusters), the presence of irregular, elongate, discontinuous dorsolateral ridges (absence of a continuous dorsolateral fold), complete interdigital webbing of the foot, and the absence of a dark inverted ‘‘V’’-shaped mark on the dorsum. We provide morphological comparisons below, based on our data, in conjunction with or with consideration of the descriptions of Stejneger (1910), Taylor (1923), Inger (1954), Brown and Alcala (1977), and Siler et al. (2009). Limnonectes beloncioi differs from L. diuatus and L. ferneri by its rounded snout in lateral aspect (vs. posteroventrally sloping), its Finger I> Finger II relative finger lengths (vs. approximately equivalent length), and by restriction of white-tipped dorsal asperities to dorsal sacral region, and not distributed in radial clusters (vs. asperities not posteriorly restricted in L. diuatus; and densely distributed across entire of dorsum, and concentrated in radial sacral clusters in L. ferneri); and the presence of irregular dorsolateral ridges (absent in L. diuatus and L. ferneri); from L. leytensis, the new species can be distinguished by its larger adult body size (SVL range 54.2–83.1 vs. 25.8.2–34.0 mm in L. leytensis), rounded snout (vs. snout moderately pointed in lateral aspect in L. leytensis), Finger I> Finger II (equivalent length in L. leytensis), complete webbing (webbing incomplete/reduced in L. leytensis), and the absence of an inverted ‘‘V’’-shaped mark on the anterior dorsum (vs. present in L. leytensis); from a large male specimen of L. macrocephalus (the species endemic to the Luzon PAIC landmasses of Luzon, Polillo, Catanduanes, and Marinduque), the new species can be distinguished by the observation that it attains a considerably smaller maximal adult male body size (SVL range 54.2– 83.1 vs. 78.9–144.6 mm in L. macrocephalus); the new species also possesses a fully exposed tympanum (vs. dorsal and/or posterior edge of tympanum hidden beneath overlapping supratympanic dermal ridge skin in L. macrocephalus) and lacks sexual size dimorphism (Table 2), whereas L. macrocephalus exhibits reverse sexual size dimorphism (males larger); from a large adult male specimen of L. magnus, the new species can similarly be distinguished by its smaller adult body size (SVL range 54.2–83.1 vs. 66.3–164.4 mm in L. magnus), rugose middorsal skin texture (vs. smooth to shagreened in L. magnus), fully exposed tympanum (vs. dorsal and/or posterior edge of tympanum hidden beneath overlapping supratympanic dermal ridge skin in L. magnus), rounded snout (vs. pointed in L. magnus), and by the absence of reverse sexual size dimorphism (present in L. magnus); from L. parvus, L. micrixalus, and L. palavanensis, the new species can be distinguished by its larger adult body size (SVL 54.2–83.1 mm; vs. 24.2–35.5 in L. parvus; 28.1–30.2 in L. micrixalus; 30.0–37.6 in L. palavanensis), rugose (vs. smooth) dorsal skin, Finger I> Finger II (equivalent length), the presence (vs. absence) of white-tipped sacral asperities and the presence of irregular, discontinuous dorsolateral ridges (vs. asperities absent, dorsolateral folds continuous), complete webbing (vs. reduced), and by the absence (vs. presence) of an inverted ‘‘V’’-shaped middorsal marking (vs. present); the new species is additionally distinguished from these species by the absence of sexual size dimorphism (vs. females larger in L. parvus, L. micrixalus, and L. palavanensis); from L. visayanus, L. beloncioi is readily diagnosed by its rounded snout (vs. pointed in L. visayanus), a tendency towards longer adult male fangs (2.6–5.6 vs. 1.8–3.0 mm in L. visayanus), by the presence (vs. absence) of white-tipped sacral asperities; finally, the new species can be distinguished from L. woodworthi by its longer male fangs (2.6–5.6 vs. 1.3– 1.6 mm in L. woodworthi), moderately rugose middorsal skin (vs. smooth in L. woodworthi), rounded snout (vs. snout moderately pointed in L. woodworthi), the presence (vs. absence) of white-tipped sacral asperities, and by the absence (vs. presence) of continuous dorsolateral folds.

Spea bombifrons (Cope, 1863), Great Plains Spadefoot New record. First record for Ojinaga Municipality: found calling in cattle tank along E–W road across northern edge of Llano Amapolas (29.02702° N, 104.16879° W; WGS84), 16 May 2016, Sean P. Graham, Mark W. Herr, and Tomas Hernandez (SRSU-D 37). Remarks. A chorus of about 5–7 calling males heard; 1 was recorded calling and photographed. There are only a handful of records for this explosively-breeding frog from Chihuahua; this record extends the species’ range in the state some 200 km from the nearest populations to the west (Municipality of Chihuahua) and southwest (Municipality of Camargo). There are also closer records to the north from Presidio and Brewster County, Texas (Dixon 2013, Graham and Kelehear 2014)., Published as part of Hernandez, Tomas, Herr, Mark W., Stevens, Skyler, Cork, Karlee, Medina-Nava, Carolina, Vialpando, C.

A phylogenetic taxonomy of species in the Cyrtodactylus peguensis group from the Ayeyarwady Basin of Myanmar is constructed based on color pattern, morphology, and molecular systematic analyses using the mitochondrial gene NADH dehydrogenase subunit 2. Newly collected samples from the type locality of C. peguensis and other localities indicate that this clade is endemic to central Myanmar and contains at least seven species, four of which are undescribed. Three species, including C. peguensis occur in the low hills of the Bago Yoma Range within the central portion of the Ayeyarwady Basin. Two of these, C. myintkyawthurai sp. nov. from the northern and central Bago Yoma and C. meersi sp. nov. which is syntopic with C. peguensis in the southern Bago Yoma are described herein. As more lowland hilly areas bordering, and within the Ayeyarwady Basin are surveyed, more new species of this group are likely to be discovered. These discoveries continue the recent surge of descriptions of new species of Cyrtodactylus that are being discovered in Myanmar. [ABSTRACT FROM AUTHOR]

CYRTODACTYLUS ,KARST ,CLADISTIC analysis ,SQUAMATA ,GECKOS ,REPTILES - Abstract
An integrative phylogenetic taxonomic analysis recovers three additional new species of karst-associated
Cyrtodactylus Gray (Squamata: Gekkonidae) -C. bayinnyiensis sp. nov.,C. chaunghanakwaensis sp. nov. andC. naungkayaingensis sp. nov. - from a narrow zone in the Salween Basin of Kayin and Mon states in eastern Myanmar from which nine new species were recently described. This degree of unprecedented diversity and site-specific endemism will no doubt continue to rise when at least 44 unsurveyed karstic habitat-islands in this same area are also explored. These data indicate that karst habitats not only serve as foci for speciation, but their rugged terrain spares them from agricultural development and, as such, they are the only habitats in the Salween Basin wherein much of the pre-agricultural herpetofauna can survive. This continues to underscore the fact that karst habitats in Myanmar harbour a significant portion of that country’s herpetofauna, some of which remains undescribed. Despite eastern Myanmar constituting some of the most extensive karstic regions in South-east Asia, they are the least legally protected, with only 1% of their terrain recognised as vulnerable. Until karst habitats in Myanmar are thoroughly investigated, a significant portion of this country’s herpetological diversity will remain underestimated and unprotected. Therefore, issues associated with karst conservation and management in Myanmar should be elevated to a new level of urgency. [ABSTRACT FROM AUTHOR]- Published
