A New Species

A new species of Ptyctolaemus Peters, 1864 is described from Htamanthi Wildlife Sanctuary, Sagaing Division, Myanmar. The new species differs from P. gularis and Ptyctolaemus aff. gularis from Tibet, China, by having relatively longer limbs and different colorations of the gular region, and it differs from P. collicristatus by having much longer limbs and a less developed nuchal crest in males. Moreover, the new species differs genetically from Ptyctolaemus aff. gularis from Tibet, China, and P. collicristatus by an uncorrected percentage distance of 23.5% and 24.8%, respectively, inferred from mitochondrial NADH dehydrogenase subunit 2 gene sequences. This discovery increases the number of known Ptyctolaemus species to three.

A New Species

A new species of the gekkonid genus Hemiphyllodactylus is described from forested karst hills near Zhutangxiang town, Lancang Lahu Autonomous County, Yunnan, China. Hemiphyllodactylus zhutangxiangensis sp. nov. is distinguished from all other congeners in morphology and an uncorrected pairwise sequence divergence of greater than 14% based on 1039 base pairs of the mitochondrial NADH dehydrogenase subunit 2 gene (ND2). The new species is defined by the following characters: a maximum SVL of 44.42 mm; 7–9 chin scales; enlarged postmentals; five circumnasal scales; 2–4 internasal scales; 8–11 supralabial scales; 8–11 infralabial scales; subdigital lamellae on fingers II–V (3–5)-(4–6)-(4 or 5)-(4 or 5); subdigital lamellae on toes II–V (4 or 5)-(4 or 5)-(4–6)-(4 or 5); dorsal scales 11–15; ventral scales 5–7; 20–23 continuous femoroprecloacal pores; having pale-grey base color on the body with various darker transverse dorsal blotches; a dark postorbital stripe extending to at least to the base of the neck; no dark dorsolateral or ventrolateral stripe on trunk; and postsacral marking bearing a dark fork-like pattern with anteriorly projecting arms. The new species brings the species total of Hemiphyllodactylus in China to 11.

A New Species

A new species of Cyrtodactylus from Tak Province, Thailand, Cyrtodactylus amphipetraeus sp. nov., is described using an integrative taxonomic analysis based on morphology, color pattern, and the mitochondrial gene NADH dehydrogenase subunit 2 (ND2). The phylogenetic analyses place the new species within the C. sinyineensis group which was previously thought to be endemic to the Salween Basin in southern Myanmar. The phylogeny also places C. inthanon in the C. sinyneensis group which is expanded herein to also include the group’s sister species C. doisuthep. Along with C. amphipetraeus sp. nov., these are the first three species of the C. sinyineensis group to be found outside of Myanmar east of the Tenasserim Mountains. The Tenasserim Mountain region is discussed as an area of cladogeneic turnover.

Wet Zone

Examination of the Dendrelaphis bifrenalis populations on Sri Lanka showed that there are two populations that are morphologically different from each other. One population is distributed only in the wet zone forests (hereafter treated as wet zone population), while the other population occurs widely in the dry zone and intermediate zones (hereafter dry zone population). The type series of D. bifrenalis consist of 3 specimens from which the specimen representing the dry zone population was chosen as lectotype, and the wet zone population is described here as a new species. It clearly differs from D. bifrenalis by having a shorter snout, orbit diameter 103–114% of eye–nostril length (vs 77–95%), and larger eye, orbit diameter 21–23% of head length (vs 17–20%). Furthermore it differs by having a temporal stripe stopping just beyond the neck (vs continues behind neck), the absence of black transverse dorsolateral bars on the anterior 1/4th of body (vs prominent), a narrow and pointed snout (vs broad and flat), a divided nasal (vs single), and a ventrolateral stripe continuing up to the tail (vs stopping at the level of the anal plate). This morphological differentiation is supported by the divergence in the mitochondrial NADH dehydrogenase subunit 4 (ND4) region separating clearly with the divergence of 1.70±0.35%. Also, here we resurrect D. effrenis (Werner, 1909) as a valid species, and D. sinharajensis as a junior synonym of it. The holotype of D. sinharajensis was chosen as the neotype of D. effrenis to stabilize nomenclature, and to make it an objective synonym. The third and fourth known specimens of this rare species are reported. A key of the species of the genus Dendrelaphis in Sri Lanka is provided.

A New Species

We describe a new Diploderma species from Southern Yunnan Province, China. It is morphologically similar to D. chapaense, D. hamptoni, and D. yunnanense, but can be distinguished from these three species and all other congeners by its unique morphometric and meristic characters, color patterns and localized distribution range. Moreover, phylogenetic analyses of mitochondrial gene NADH dehydrogenase subunit 2 sequence data also supports this point of view; the new species differs genetically from investigated congeners by percentage distance of 8.78 to 21.15%.

Two New Species

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.

A New Species

We describe a new species of the newt genus Tylototriton from Umphang Wildlife Sanctuary, Tak Province, western Thailand based on molecular and morphological evidence and named here as Tylototriton umphangensissp. nov. The new species is assigned to the subgenus Tylototriton and differs from other species in having dark-brown to blackish-brown body and limbs, truncate snout, prominent antero-medial ends of the expansion of the dentary bones, laterally protruding quadrate regions, indistinct and small rib nodules, a well-segmented vertebral ridge, and rough dorsolateral bony ridges, which are steeper anterior, and curved medially at the posterior ends. The molecular data show that Tylototriton umphangensissp. nov. differs from T. uyenoi sensu stricto by a 5% genetic sequence divergence of the mitochondrial NADH dehydrogenase subunit 2 region gene. The new species and T. uyenoi are both endemic to Thailand, distributed along the Northwest Thai (Dawna) Uplands of Indochina. To clarify the species boundary between Tylototriton umphangensissp. nov. and T. uyenoi, additional field research is needed in adjacent areas. Tylototriton umphangensissp. nov. is restricted to evergreen hill forests in Umphang Wildlife Sanctuary. We suggest that the new species should be classified as Endangered (EN) in the IUCN Red List.

We describe two new insular gecko species of the genus Cnemaspis from Tarutao, Adang, and Rawi islands in Satun Province, southern Thailand. The new species are distinguished from their congeners in having a unique combination of morphological, scalation, and color pattern characters, and by genetic divergence in the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene. Cnemaspistarutaoensissp. nov. was found to be a member of the C.kumpoli group, but is distinguished from all other species in that group by having 8–9 supralabials and 8 infralabials; 4–5 pore-bearing precloacal scales, pores rounded; 17–19 paravertebral tubercles randomly arranged; 27–29 subdigital lamellae under the fourth toe; subcaudal region yellowish, with smooth scales and a single enlarged median row; black gular markings in males and females; and 17.24–22.36% uncorrected pairwise sequence divergences. Cnemaspisadangrawisp. nov. was found to be a member of the C.siamensis group, but is distinguished from all other species in that group by having 10 supralabials and 9 infralabials; 6–8 pore-bearing precloacal scales, pores rounded and arranged in a chevron shape; 23–25 randomly arranged, separated paravertebral tubercle rows; 26–28 subdigital lamellae under the fourth toe; subcaudal scales keeled, without enlarged median row; gular region, abdomen, limbs and subcaudal region yellowish in males only; gular marking absent in males and females; and 8.30–26.38 % uncorrected pairwise sequence divergences. Cnemaspistarutaoensissp. nov. occurs in karst formations on Tarutao Island, while Cnemaspisadangrawisp. nov. is found near granitic, rocky streams on Adang and Rawi islands.
