Comments on the taxonomic status of Cyrtodactylus zebraicus Taylor, 1962 (Squamata: Gekkonidae) from Northern Peninsular Malaysia.

Recent collections confirmed the presence of this species in the northernmost state of Perlis and for the country. An expanded description of the newly collected Peninsular Malaysian specimens as well as the holotype of C.

A new species of the group (Squamata, Gekkonidae) from the uplands of western Thailand.

An integrative systematic analysis recovered a new species of the group from the uplands of Thong Pha Phum National Park, Kanchanaburi Province in western Thailand. is deeply embedded within the group, bearing an uncorrected pairwise sequence divergence of 7.6-22.

Integrative taxonomy delimits and diagnoses cryptic arboreal species of the group (Squamata, Gekkonidae) with descriptions of four new species from Thailand.

Species delimitation and species diagnosis must remain separate operations to avoid constructing taxonomies comprised of non-monophyletic species based on morphological similarity as opposed to phylogenetic propinquity. This is particularly true for highly specialized species such as the range-restricted upland taxa in the group of Indochina where strong selection pressure for an arboreal lifestyle has contributed to morphologically similar but distantly related species. This in turn, has resulted in a history of erroneous taxonomies that have actually obscured rather than revealed the diversity within this group.

A new species in the group (Squamata, Gekkonidae) from Kanchanaburi Province, western Thailand.

is described from Si Sawat District, Kanchanaburi Province, in western Thailand. The new species superficially resembles Taylor, 1962 from southern Thailand. However, differences between the new species from and other congeners were supported by an integrative taxonomic analysis of molecular and morphological data.

Hidden diversity of rock geckos within the species group (Gekkonidae, Squamata): genetic and morphological data from southern Thailand reveal two new insular species and verify the phylogenetic affinities of and .

Two new insular rock geckos in the genus are described from Ko Samui in Surat Thani Province and Ko Similan in Phang-nga Province, southern Thailand, based on a combination of morphological and mitochondrial NADH dehydrogenase subunit 2 (ND2) data. Both new species represent divergent lineages within the species group. is distinguished from other species in the group by having eight or nine supralabial and infralabial scales; 5-8 pore-bearing precloacal scales in males, pores rounded; 25-27 paravertebral tubercles, arranged randomly; 22-25 subdigital lamellae under 4 toe; enlarged median subcaudal scale row present; gular region, abdomen, limbs and subcaudal region yellowish only in males, and uncorrected pairwise divergences of 8.

A new insular species of the group (Reptilia, Gekkonidae) from Tarutao Island, southern Thailand revealed by morphological and genetic evidence.

The bent-toed geckos of the group are widely distributed along the Thai-Malay Peninsula. Although taxonomic and phylogenetic studies of this species group have been continuously conducted, only some populations from Thailand have been included, resulting in hidden diversity within this group. In this study, we used morphological and molecular data to clarify the taxonomic status and describe a new population from Tarutao Island, Satun Province, southern Thailand.

Taxonomic reassessment and phylogenetic placement of (Reptilia, Gekkonidae) based on morphological and molecular evidence.

The taxonomy and phylogeny of the complex along the Thai-Malay Peninsular region has been the focus of many recent studies and has resulted in the recognition of 17 species. However, the majority of these studies were focused on Peninsular and insular Malaysia where there were specimens and genetic vouchers. The taxonomic status and phylogenetic relationships of the Thai species in this complex remain unresolved, due to the lack of genetic material of some species, especially and from Thai populations.

Rivers of Indochina as potential drivers of lineage diversification in the spotted flying lizard (Draco maculatus) species complex.

Southeast Asia hosts a rich concentration of biodiversity within multiple biodiversity hotspots. Indochina, a region with remarkably high levels of in situ diversification, possesses five major rivers (Ayeyarwady, Chiang Mai, Mekong, Red, and Salween), several of which coincide with phylogenetic breaks of terrestrial taxa. Draco maculatus possesses a range that stretches across Indochina, which widespread geographic distribution along with potential discrete variation within subspecies alludes to the possibility of this taxon constituting multiple divergent lineages.

Integrative taxonomy of the rock-dwelling gecko complex (Squamata, Gekkonidae) reveals a new species from Nakhon Si Thammarat Province, southern Thailand.

The rock-dwelling gecko genus is one of the most species-diverse genera of gekkonid in Thailand. Earlier studies relied on morphological data to identify species, but cryptic morphology often obscured species diversity in . In this study, an integrative taxonomic approach based on morphological characters and sequences of the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene were used to clarify current taxonomy of the complex and delimit a new species from Lan Saka District, Nakhon Si Thammarat Province, southern Thailand.

Species delimitation of crab-eating frogs ( complex) clarifies taxonomy and geographic distributions in mainland Southeast Asia.

The taxonomy and geographic distributions of species of crab-eating frogs ( complex) in mainland Southeast Asia have been highly uncertain. Three taxonomic names are used in recent literature (, , and ) but the applications of these names to localities has been inconsistent, especially owing to the lack of available molecular data for . Morphometric and mitochondrial DNA variation was examined in these frogs, including name-bearing types and topotypes of all three species.

Morphological and molecular analyses reveal two new insular species of Strauch, 1887 (Squamata, Gekkonidae) from Satun Province, southern Thailand.

We describe two new insular gecko species of the genus 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. was found to be a member of the 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.

Population demography of Oldham's leaf turtle () in protected and disturbed habitats in Thailand.

Background: Freshwater turtle populations are vulnerable to a range of human activities because of particular life history attributes, and anthropogenic impacts can cause shifts in demographic traits, including survival, density and population structure. Asian freshwater turtles have undergone dramatic population declines in recent decades principally because of collection for food, pet, and traditional medicine markets. Despite this, few studies have been conducted on the population demography of these turtles, thereby limiting our understanding of population trends and the development of conservation actions.
