An integrative taxonomic analysis of newly discovered populations of Hemiphyllodactylus from Indochina recovered a new species from Peninsular Thailand and two others from Laos. The new Thai species, Hemiphyllodactylus pardalis sp. nov. described herein, is the sister species to all other species in the newly designated Indochina clade and has a unique spotted contrasting dorsal pattern not seen in any other species of Hemiphyllodactylus. This, along with its elongate and gracile body morphology, renders it remarkably convergent on the Philippine gecko Pseudogekko smaragdinus despite the fact it is deeply nested within Hemiphyllodactylus. The description of this new species underscores the depauperate nature of Hemiphyllodactylus diversity throughout Indochina in general and Thailand in particular compared to neighboring upland areas of Myanmar and Peninsular Malaysia. This especially underscores the need for continued herpetofaunal field surveys in montane areas of western Thailand.

A new species, Cyrtodactylus durio sp. nov., is described from northwestern Peninsular Malaysia on the basis of its head, body, limbs, and tail being extremely spinose as well as other unique combinations of squamation and color pattern. It is proposed that C. durio sp. nov. forms a clade with C. brevipalmatus, C. elok, C. spinosus, and C. stresemanni on the basis of having a spiny, prehensile tail and that it is the sister species of C. stresemanni based on unique caudal tuberculation. Cytrodactylus durio sp. nov. is the latest in a growing list of new species of amphibians and reptiles recently described from the Malay Peninsula, and Peninsular Malaysia in particular, that clearly underscores the need for continuing exploratory research in these regions.

Abstract The integrated results of morphological and molecular phylogenetic analyses confirmed the new species status of a recently discovered population of Ansonia from Suan Phueng District, Ratchaburi Province, Thailand. Ansonia karensp. nov. is separated from all other species of Ansonia by a unique combination of mensural, discrete morphological, and color pattern characteristics and is the sister species of A. thinthinae from Tanintharyi Division, Myanmar. This discovery fills a geographic hiatus of 350 km between it and A. kraensis from Ranong Province, Thailand. Ansonia karensp. nov. is the newest member of a long list of range-restricted endemics having been recently discovered in the northern Tenasserim Mountain region of western Thailand and continues to underscore the unexplored nature of this region and its need for conservation.

An integrative taxonomic analysis of the Cyrtodactylus linnwayensis group of the Shan Plateau recovered two new populations from isolated karst habitats near Pinlaung Town, Shan State as a new species, C. pinlaungensis sp. nov. Cyrtodactylus pinlaungensis sp. nov. is most closely related to a clade comprising C. linnwayensis and C. ywanganensis from the western edge of the Shan Plateau approximately 90 km to the northwest. Cyrtodactylus pinlaungensis sp. nov. can be distinguished from all members of the C. linnwayensis group by a number of statistically different morphological characters, discrete color pattern differences, and its heavy tuberculation. It also bears an uncorrected pairwise sequence divergence of 5.0–7.6% from all other species combined based on the mitochondrial gene ND2 and its flanking tRNAs. The discovery of this new species on the Shan Plateau continues to underscore the fact that this region is rapidly emerging as a herpetological diversity hot-spot for Myanmar.

Molecular phylogenetic analyses of the sister species Sphenomorphus stellatus and S. praesignis based on the mitochondrial genes 12S and 16S rRNA recover the former as paraphyletic with respect to the latter in that a specimen of S. stellatus from the type locality in Peninsular Malaysia is more closely related to S. praesignis than to Indochinese populations of S. stellatus. Furthermore, the phylogeny indicates that the Indochinese populations represent two species, thus resulting in four major lineages within this clade. These relationships are consistent with multivariate and univariate analyses of morphological and discrete color pattern data which statistically define and diagnose the four lineages and together with the molecular data, provide the foundation for robust, testable, species-level hypotheses. As such, S. stellatus is herein restricted to Peninsular Malaysia; S. annamiticus is resurrected for the circum-continental populations ranging through southeastern Thailand, southern Cambodia, and southern Vietnam; a new species—S. preylangensis sp. nov.—is described from an isolated mountain, Phnom Chi, from the Prey Lang Wildlife Sanctuary in central Cambodia; and the taxonomy of S. praesignis remains unchanged. The description of S. preylangensis sp. nov. underscores the necessity to conserve this remnant of lowland evergreen rainforest in the Prey Lang Wildlife Sanctuary.

A herpetological survey of the Indawgyi Wildlife Sanctuary in Kachin State, Myanmar resulted in the discovery of a new species of Cyrtodactylus Gray along the eastern watershed of the Mokso Mountains. An integrative taxonomic analysis based on the mitochondrial ND2 gene, morphology, and color pattern recovered this new species, Cyrtodactylus mombergi sp. nov., as the sister taxon to an undescribed species from Miao, Arunachal Pradesh, India. Bayesian and maximum likelihood analyses recovered notable genetically divergent (4.7%) phylogeographic structure between northern and southern populations of C. mombergi sp. nov. across only 14 km of continuous habitat. Conversely, genetic divergence did not exceed 9.2% between C. mombergi sp. nov. and the undescribed species from Miao from across 355 km of habitat. Cyrtodactylus mombergi sp. nov. belongs to a well-supported, mitochondrial clade of 18 other species which now compose an expanded and redefined C. gansi group. Cyrtodactylus mombergi sp. nov. is only the third species of Bent-toed Gecko reported from Kachin State and indicates that additional herpetological surveys are needed in unexplored forested areas.

A new species of the scincid genus Larutia, L. penangensis sp. nov., from Pulau Pinang, Peninsular Malaysia is separated from all other congeners by having the unique characteristics of the complete absence of limbs, four supralabials, large body scales, and no banding or striping pattern. Additionally, it has the following unique combination of characters that further separates it from all congeners: a single presubocular; separated nasals; paired frontoparietals; small, widely separated prefrontals; no supranasals or postnasal; two postsupralabials; and large, posterior chinshields that contact the infralabials. A molecular phylogeny based on one mitochondrial and two nuclear genes from all species of Larutia from Peninsular Malaysia indicates L. penangensis sp. nov. is most basal and that L. seribuatensis is the sister lineage to a clade containing L. miodactyla and the sister species L. trifasciata and L. larutensis. Consistencies and inconsistencies between this phylogeny and a previously proposed morphological phylogeny are discussed.

We describe a new species of lizard in the genus Eutropis Fitzinger 1843 from the southwestern tip of the Zamboanga Peninsula on the western part of Mindanao Island, Philippines. The new species is related to Eutropis rugifera, which is a secretive, forest-adapted skink that ranges widely outside the Philippines from the western extent of its distribution on Nicobar Island (the type locality) through southern Peninsular Malaysia, Sumatra, and the Mentawai islands, Borneo, Java, and as far east as Bali Island. The discovery of a new, morphologically distinct, and genetically highly divergent Sun Skink lineage in the low elevation forests of the Zamboanga Peninsula creates a puzzling disjunct geographic distribution (E. rugifera has not been reported from the Sulu Archipelago). The new species is estimated to have diverged ~10–16 mya from E. rugifera, from which it appears to have an extralimital and isolated distribution. Considering the dynamic geological history and ancient continental origin of the Zamboanga Peninsula, colonization by the new species may have been facilitated by pre-Pleistocene overseas long-distance dispersal, saltatory range expansion, and subsequent contraction/extinction in the Sulu Archipelago, and/or possibly paleotransport on the ancient crustal fragment of Zamboanga. The new species is known only from Zamboanga City’s primary surface water supply catchment at the lowest elevations inside the boundaries of Pasonanca Natural Park, despite the fact that there have been historical surveys of herpetological diversity at multiple sites to the northeast (Zamboanga, western Mindanao) and to the southwest (Sulu Archipelago). The new species, thus, may be limited to just the tip of the Zamboanga Peninsula, possibly rendering KEYWORDS: IUCN Red List, Palawan microcontinent block, Pasonanca Natural Park, Sulu Archipelago, Surface catchment watershed biodiversity

A new species of limestone karst-adapted gecko of the Cyrtodactylus pulchellus complex, C. dayangbuntingensis sp. nov., is described from Dayang Bunting Island of the Langkawi Archipelago off the northwest coast of Peninsular Malaysia. It is the third species of the group to be described from the archipelago after C. langkawiensis and C. macrotuberculatus. The new species can be distinguished from all other species of Cyrtodactylus based on molecular evidence from the mitochondrial gene ND2 and its flanking tRNAs as well as having unique combinations of morphological and color pattern characteristics. This discovery underscores the need for continued surveys of the many islands in the archipelago to properly ascertain its true herpetological diversity.

A new species of the gekkonid lizard, Cytrodactylus macrotuberculatus sp. nov., is described from Pulau Langkawi of the Langkawi Archipelago located off the northwest coast of Peninsular Malaysia in the state of Kedah. This species had been previously recognized as C. pulchellus but is differentiated here from that species and all other Sunda Shelf Cyrtodactylus on the basis of its strong tuberculation and other scale and color pattern characteristics. This represents the second endemic species known from the Langkawi Archipelago.

A new endemic species of Gekko, G. russelltraini, is described from Chua Chan Mountain, an isolated granitic peak in the Xuan Loc district, Dong Nai province, southeastern Vietnam. The species is distinguished from its congeners by its moderate size (SVL 70.3–82.9 mm), 8–11 precloacal pores in males, 12–16 longitudinal rows of very weakly enlarged, smooth dorsal tubercles, 17–18 lamellae beneath digit IV of pes, and dorsal pattern of five to seven white vertebral blotches between nape and sacrum and four to seven pairs of short white bands on flanks between limb insertions. Gekko russelltraini is a member of a group of mid-sized Indochinese Gekko sharing similar habitus, scalation, and color pattern elements and is the seventh member of its genus confirmed for Vietnam.
