The snake genus Oligodon, known for its egg-eating feeding behaviour, is a taxonomically and systematically challenging group from South and Southeast Asia. This work provides the first phylogenetic hypothesis for the genus, and includes a checklist and key to the species. I use approximately 1900 base pairs of mitochondrial DNA sequence data to infer the relationships of these snakes, and I examine congruence between the molecular phylogeny and hemipenial characters. A hypothesis for the position of Oligodon within the Colubridae is also proposed. I discuss the implications of the phylogeny for previous taxonomic groupings, and consider the usefulness of the trees in analysis of behaviour and biogeography.
