Caenophidian snakes include the file snake genus Acrochordus and advanced colubroidean that radiated mainly during Neogene. Although caenophidian are a well-supported clade, their inferred affinities, based either on molecular or morphological data, remain poorly known controversial. Here, we provide an expanded phylogenetic analysis of Caenophidia use three non-parametric measures support-Shimodaira-Hasegawa-Like test (SHL), Felsentein (FBP) transfer (TBE) bootstrap measures-to evaluate...

Molecular phylogenetic analyses of the sister species Sphenomorphus stellatus and S. praesignis based on mitochondrial genes 12S 16S rRNA recover former as paraphyletic with respect to latter in that a specimen from type locality Peninsular Malaysia is more closely related than Indochinese populations stellatus. Furthermore, phylogeny indicates represent two species, thus resulting four major lineages within this clade. These relationships are consistent multivariate univariate morphological...

The Southeast Asian cascade frog, Rana livida (Blyth, 1856), has long been suspected to be a complex of species. Several different forms are described from across its vast range. loss type material and disparate sampling efforts challenges. Is variability in this species due geographic variation or the presence multiple species? We use concordant evidence morphology, morphometrics, cellular DNA content, allozyme electrophoresis investigate diversity R. Vietnam. Three distinct recognized on...

We describe a new species of the genus Zhangixalus Li, Jiang, Ren &amp; 2019 from Ha Giang Province, Vietnam based on morphological and molecular data. In phylogenetic analyses, is nested in duboisi (Ohler, Marquis, Swan Grosjean, 2000) group, where it sister to Z. with genetic distance 2.51%. The species, franki sp. nov., differs its congeners by combination following characters: size large, SVL 77.9–85.8 mm males; finger webbing formula I1-1II0-1III½-0IV; dorsal surface head body green...

Asian Mountain Toads (Ophryophryne) are a poorly known genus of mostly small-sized anurans from southeastern China and Indochina. To shed light on the systematics within this group, most comprehensive mitochondrial DNA phylogeny for to date is presented, taxonomy biogeography group discussed. Complimented with extensive morphological data (including associated statistical analyses), molecular indicates that Langbian Plateau, in southern Annamite Mountains, Vietnam, one diversity centres...
