Although tortoises of the family Testudinidae represent a familiar and widely distributed group of turtles, their phylogenetic relationships have remained contentious. In this study, we included 32 testudinid species (all genera and subgenera, and all species of Geochelone, representing 65% of the total familial species diversity), and both mitochondrial(More)
The turtle family Kinosternidae comprises 25 living species of mud and musk turtles confined to the New World. Previous attempts to reconstruct a phylogenetic history of the group have employed morphological, isozyme, and limited mitochondrial DNA sequence data, but have not been successful in producing a well-resolved phylogeny. With tissues from every(More)
We describe a new species of the genus Hemiphyllodactylus on the basis of four specimens from Cao Bang Province, northern Vietnam. Hemiphyllodactylus zugi sp. nov. is distinguished from the remaining congeners by a combination of the following characters: a bisexual taxon; average SVL of adult males 41 mm, of adult female 46.6 mm; chin scales bordering(More)
Several important aspects of the evolution of the softshell turtle (family Trionychidae) have not been addressed thoroughly in previous studies, including the pattern and timing of diversification of major clades and species boundaries of the critically endangered Shanghai Softshell Turtle, Rafetus swinhoei. To address these issues, we analyzed data from(More)
Phylogenetic relationships and taxonomy of the short-necked turtles of the genera Elseya, Myuchelys, and Emydura in Australia and New Guinea have long been debated as a result of conflicting hypotheses supported by different data sets and phylogenetic analyses. To resolve this contentious issue, we analyzed sequences from two mitochondrial genes (cytochrome(More)
The members of the genus Muntiacus are of particular interest to evolutionary biologists due to their extreme chromosomal rearrangements and the ongoing discussions about the number of living species. Red muntjacs have the largest distribution of all muntjacs and were formerly considered as one species. Karyotype differences led to the provisional split(More)
A male snake collected in Louangphabang Province and a second specimen observed in Houaphan Province, North Laos, share morphological characters with the Asian genus Fimbrios Smith, 1921, including erected edges on the first supra- and infralabial scales, but differ in the following morphological characters: fewer dorsal scale rows (25-27 vs. 30-33), fewer(More)
