A new species of the Cnemaspis siamensis group is described from Wang Khrachae District, Kanchanaburi Province, western Thailand based on morphological and molecular data. The species, enneaporus Rujirawan, Aksornneam & Aowphol, sp. nov. , distinguished other in C. by having combination SVL 42.2 mm adult male ( n = 1), 43.7 female 1); eight supralabials; seven or infralabials; ventral scales smooth; nine continuous precloacal pores male; 17 18 paravertebral tubercles linearly arranged;...
Phylogenetic and morphological analyses delimit diagnose, respectively, a new population of karst-dwelling Cyrtodactylus from extreme northern Thailand. The species, phamiensis sp. nov. , the chauquangensis group inhabits karst caves outcroppings vegetation in vicinity Pha Mi Village Chiang Rai Province, Within group, is earliest diverging species strongly supported clade composed granite-dwelling C. doisuthep sister 6 erythrops . nearly continuous karstic habitat between type locality its...
We report on the discovery of a new genus microhylid subfamily Asterophryinae from northern and eastern Indochina, containing three species. Vietnamophryne <strong>Gen. nov.</strong> are secretive miniaturized frogs (SVL<21 mm) with mostly semi-fossorial lifestyle. To assess phylogenetic relationships, we studied 12S rRNA-16S rRNA mtDNA fragments final alignment 2 591 bp for 53 External morphology characters osteological characteristics analyzed using micro-CT scanning were used describing...
An integrative systematic analysis recovered a new species of the Cyrtodactylusbrevipalmatus group from uplands Thong Pha Phum National Park, Kanchanaburi Province in western Thailand. Cyrtodactylusthongphaphumensissp. nov. is deeply embedded within brevipalmatus group, bearing an uncorrected pairwise sequence divergence 7.6-22.3% all other based on 1,386 base pair segment mitochondrial NADH dehydrogenase subunit 2 gene (ND2) and adjacent tRNAs. It diagnosable by statistically significant...
Species delimitation and species diagnosis must remain separate operations to avoid constructing taxonomies comprised of non-monophyletic based on morphological similarity as opposed phylogenetic propinquity. This is particularly true for highly specialized such the range-restricted upland taxa in
A new species of rock-dwelling Leiolepis is described from the Khorat Plateau in northeastern Thailand. glaurung sp. nov. can be differentiated all other sexual by a combination having black gular region with wide medial yellow stripe, ventrum mottling, bright red to orange subcaudal coloration, reduced no expandable flanks, and only one transverse bar on flanks. This first rocky habitat-adapted . demonstrates numerous ecological adaptations survive these habitats. are known for their flanks...
Cyrtodactylusmonilatussp. nov. is described from Si Sawat District, Kanchanaburi Province, in western Thailand. The new species superficially resembles C.zebraicus Taylor, 1962 southern However, differences between the and other congeners were supported by an integrative taxonomic analysis of molecular morphological data. Phylogenetic analyses based on mitochondrial NADH dehydrogenase subunit 2 (ND2) gene showed that a member C.oldhami group closely related to Cyrtodactylus sp. MT468911...
Thailand is a world biodiversity hotspot with 176 known snake species. However, anthropogenic influences on snakes associated growing human populations are poorly understood. Aquatic funnel traps (AFTs) in widespread use agricultural areas throughout Thailand, and they have the ability to collect large quantities of by-catch, including snakes. During an on-going study human-snake conflict we found, using radio-telemetry, one our radio-tracked Bungarus candidus (Malayan Krait) individuals...
ABSTRACTDeforestation is a major threat to biodiversity worldwide, especially in Southeast Asia. In western Thailand, reptiles are an important part of tropical rainforest ecosystems and karst forests. However, basic ecological studies many species largely lacking. Therefore, we studied two sympatric gecko species, Cyrtodactylus saiyok C. tigroides, that inhabit forests restricted Thailand. We investigated the habitat variables affect their abundance body condition Kanchanaburi Province...
We described a new species of elapid snake genus Bungarus from the Tenasserim Mountain Range in Ratchaburi Province, western Thailand. sagittatus sp. nov. can be distinguished all congeners by having combination 15 dorsal scale rows; 215–217 ventral scales; 48–56 undivided subcaudal; prefrontal suture 2.4–2.6 times length internasal suture; anterior chin shields larger than posterior shields; head adult uniform black while juvenile with small dim white patches on temporal and parietal areas;...
Several conservation assessments have proposed that the Kanchanaburi pit viper Trimeresurus kanburiensis is threatened with extinction due to limited distribution, few documented sites and collection of mature individuals for international pet trade. No previous study has evaluated these threats comprehensively, nor investigated natural history species in wild. To address knowledge gaps, we began a brief review wildlife trade reports then during September–November 2020 undertook field...
We describe a new species of the gekkonid genus Cnemaspi s from Erawan National Park in Kanchanaburi Province western Thailand. Molecular phylogenetic analyses, based on mitochondrial NADH dehydrogenase subunit 2 gene and flanking tRNAs, revealed that Cnemaspis auriventralis sp. nov. is nested within C. siamensis group closely related to huaseesom , but has uncorrected pairwise genetic divergences 12.12–27.92% all other group. The also distinguished by having combination snout-vent length...
