Molecular phylogeny reveals distinct evolutionary lineages of the banded krait, Bungarus fasciatus (Squamata, Elapidae) in Asia

The banded krait, Bungarus fasciatus is a widespread elapid snake, likely to comprise several distinct species in different geographic regions of Asia. Therefore, based on molecular phylogenetics and comparative morphology data, we present an overview of the systematic composition of the species to delimit potential biogeographic boundaries. Our phylogenetic analyses, based on four mitochondrial genes, reveal the existence of at least three evolutionary lineages within B. fasciatus, corresponding to Indo-Myanmar, Sundaic and eastern Asian lineages. We are convinced that there are at least three taxonomic entities within the nomen B. fasciatus and restrict the distribution of B. fasciatus sensu stricto to the Indo-Myanmar region. We also provide additional natural history data of the taxon from eastern India. Finally, we advocate further studies to establish the degree of reproductive isolation among these diverging evolutionary lineages and to reassess the systematic status of this species complex especially the Sundaic and eastern Asian lineages

Systematics and ecology of Oligodon sublineatus Duméril, Bibron & Duméril, 1854, an endemic snake of Sri Lanka, including the designation of a lectotype

The description of Oligodon sublineatus Duméril, Bibron & Duméril, 1854 was based on two syntypes located at Paris Natural History Museum (MNHN). The larger specimen (SVL 254 mm) was described in detail, but erroneously labelled as originating from the Philippines, the second specimen (SVL 150 mm) was labelled as originating from ‘Ceylan’ (=Sri Lanka). The smaller specimen, up to this point, has always been considered as the holotype by monotypy. Since recognising the larger specimen in the collection of MNHN as a syntype, we hereby designate it as the lectotype of Oligodon sublineatus and redescribe comprehensively both syntypes. Oligodon sublineatus (SVL 152–310 mm) has 130–161 ventral scales, 23–42 divided subcaudals, a divided anal plate, a loreal, seven supralabials, and 1+2 temporals. Furthermore, we provide a detailed account of the distribution and natural history of this widely distributed Sri Lankan endemic snake
