Molecular Systematics and Phylogeny of Old and New World Ratsnakes, Elaphe Auct., and Related Genera (Reptilia, Squamata, Colubridae)
The phylogenetic relationships of the Holarctic ratsnakes (Elaphe auct.) are inferred from portions of two mitochondrial genes, 12S rRNA and COI, and another new genus is described for four Oriental species.
The Oriental Colubrine Genus Coelognathus Fitzinger, 1843 and Classification of Old and New World Racers and Ratsnakes (Reptilia, Squamata, Colubridae, Colubrinae)
The phylogenetic relationships of the colubrine genus Coelognathus is examined on the basis of two partially sequenced mitochondrial genes, COI and 12S rRNA, and a new generic name, Oreocryptophis, is proposed for the East Asian ratsnake taxon Coluber porphyraceus Cantor.
Two New Species of the Genus Gonydactylus (Sauria: Gekkonidae) from Eastern Nepal
Two new species of the naked-toed geckos of the genus Gonydactylus are described from Eastern Nepal. A comparison of the described species with another “himalayan” Gonydactylus ( G. khasiensis and…

This work has assessed the intraspecific morphological variation and phylogeographic relationships among specimens from different locations across its updated distribution and provides sufficient evidence to support three distinct lineages within the Z. h.
New Mountain Species of Trimeresurus (Serpentes, Viperidae, Crotalinae) of the «Green» Pit Vipers Group from the Himalayas
New species of Trimeresurus of the «green» pit vipers group is described from Himalayas in Central Nepal. Its comparison with the most related mountain species from Tibet, China is given with…
Morphological Adaptations for Egg-Eating in the Snake Elaphe davidi Sauvage 1884
Morphological similarities with the stenophagous African Dasypeltis scabra and the Far Eastern euryphagous Elaphe climacophora indicate that eggs may constitute an occasional or rather seasonal diet in Elaphes davidi.
