New data on the distribution, morphology, and molecular systematics of two venomous snakes, Bungarus niger and Bungarus lividus (Serpentes: Elapidae), from north-east India. pp. 219-228 plus Supplementary documents.

Abstract. This paper provides new information on the two medically important snakes, Bungarus niger and B. lividus from northeastern India. Included are morphological data on both the species and for the first time, genetic data (cytb) on B. lividus and establishing the genetic relation of the species to its congeners. We also provide brief descriptions of hemipenial morphology and new distributional records for both the species, along with notes on their natural history.

Key words. Squamata, Assam, greater black krait, lesser black krait, Meghalaya, Mizoram, natural history, phylogeny.
