A new species of karst-dwelling bent-toed gecko of the group (Squamata, Gekkonidae) from eastern Thailand and the phylogenetic placement of .

A new karst-dwelling bent-toed gecko of the group is described from Khlong Hat District, Sa Kaeo Province, eastern Thailand, based on an integrative taxonomic analysis of genetic data and morphological characteristics. Phylogenetic analyses using the mitochondrial NADH dehydrogenase subunit 2 (ND2) gene revealed that topotypes of were sister to a clade containing from Cambodia, an unnamed lineage from Sakaerat Biosphere Reserve in Nakhon Ratchasima Province, Thailand, and the Khlong Hat lineage described here as Multivariate analyses of morphometric and meristic characters showed that is morphologically distinct from all other species in the group by having the combination of SVL 76.5-82.

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 (Anura: Dicroglossidae) from Southern Thailand.

A new species in the dicroglossid frog genus is described from Ko Pha-ngan, Ko Samui, and Ko Lanta Yai Islands in southern Thailand. Males of  . lack a caruncle on top of the head and very closely resemble (Boulenger, 1887) from Myanmar and western and southern Thailand.

A new species of Cyrtodactylus Gray (Squamata; Gekkonidae) from the Thai Highlands with a discussion on the evolution of habitat preference.

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.

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.

A new Limnonectes (Anura: Dicroglossidae) from southern Laos.

A new species of "fanged frog" in the genus Limnonectes resembling L. kohchangae (Smith, 1922) from southeastern Thailand and southwestern Cambodia is described from upper elevations of the Bolaven Plateau, southern Laos. However, the new species, L.
