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

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.

Nd2 Gene

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.

Two New Species

Two new species of Bent-toed Geckos of the Cyrtodactylus peguensis group are described from foothill areas occurring on opposite sides of the Ayeyarwady Basin. Cyrtodactylus nyinyikyawi sp. nov. from the Shwe Settaw Wildlife Sanctuary, Magway Region in the east and C. pyadalinensis sp. nov. from the Panluang-Pyadalin Wildlife Sanctuary, Shan State in the west bear unique suits of morphological and color pattern character states separating them from all species in the peguensis group. Additionally, a molecular phylogeny based on the mitochondrial gene ND2 indicates that neither species is nested within, nor sister to any known species in the group. This study augments recent and ongoing studies showing that the Ayeyarwady Basin is herpetologically more diverse than previously considered and should be incorporated into ongoing discussions concerning conservation efforts in Myanmar.

Molecular Phylogenetic

Two new species, Hyphessobrycon frickei Guimarães, Brito, Bragança, Katz & Ottoni sp. nov. and H. geryi Guimarães, Brito, Bragança, Katz & Ottoni sp. nov., are herein described, based on seven different and independent species delimitation methods, and on molecular and morphological characters, making the hypothesis of these new species supported from an integrative taxonomy perspective. They belong to the “Rosy tetra” clade, which is mainly characterized by the presence of a dark brown or black blotch on the dorsal fin and the absence of a midlateral stripe on the body. These two new species are distinguished from the other members of this clade mainly by the arrangement, shape and color pattern of humeral and dorsal-fin spots, as well as by other characters related to scale counts and body pigmentation. The placement of the new species within the “Rosy tetra” clade was based on the combination of morphological character states mentioned above and corroborated by a molecular phylogenetic analysis using the mitochondrial gene cytochrome oxidase subunit 1. In addition, a new clade (here termed Hyphessobrycon copelandi clade) within the “Rosy tetra” clade is proposed based on molecular data, comprising H. copelandi, H. frickei sp. nov., H. geryi sp. nov. and a still undescribed species. Our results corroborate the occurrence of hidden species within the “Rosy tetra” clade, as suggested by previous studies.

Clade 1

A new gekkonid lizard, Cyrtodactylus maelanoi sp. nov., from Mae Hong Son Province of the Thai Highlands is described using an integrative taxonomic analysis based on morphology, color pattern, and the mitochondrial gene NADH dehydrogenase subunit 2 (ND2) and its flanking tRNAs. Phylogenetic analyses place the new species within clade 1 of the C. sinyineensis group and as the sister species to C. inthanon with an uncorrected pairwise sequence divergence of 3.9%. Collection data gathered in the field indicate that C. maelanoi sp. nov. is a habitat generalist. Reconstruction of the ancestral habitat preference for the C. sinyineensis group by way of stochasitc character mapping (SCM) indicates that karstic environments were the ancestral condition out of which the general habitat preference of the ancestor of C. maelanoi sp. nov. and C. inthanon and that of C. amphipetreaus and C. doisuthep evolved three times independently. Additionally, SCM demonstrated that the evolution of a granitic habitat preference from a karst-adapted ancestor happened in C. aequalis. The discovery of a new upland species in the Thai Highlands brings into focus the understudied nature of the mountain systems of western Thailand and the need for their continued exploration and conservation.

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

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%.

An integrative taxonomic analysis of the 10 species of the Cyrtodactylus sinyineensis group based on squamation, color pattern, and the mitochondrial gene NADH dehydrogenase subunit 2 (ND2) and its flanking tRNA regions, recovered the newly discovered populations from Datt Kyaik and Taung Wine Hills in Kayin State as the new species Cyrtodactylus dattkyaikensis sp. nov. and C. taungwineensis sp. nov. The Maximum Likelihood and Bayesian phylogenetic estimates supported C. dattkyaikensis sp. nov. as the sister species of C. bayinnyiensis and C. taungwineensis sp. nov. as the sister species of C. sinyineensis. Each new species is differentially diagnosable from all other C. sinyineensis group species based on their morphological placement in multivariate space and several statistically significant mean differences is meristic squamation and color pattern data. The C. sinyineensis group ranges across an archipelago of karstic habitat-islands in the Salween Basin of southern Myanmar. The discovery of these new species continues to underscore the unprecedented high degree of diversity and site-specific endemism in this relatively small region and the urgent need for the conservation of its karstic terranes.
