Phylogenetic position of Tropidophorus assamensis Annandale, 1912 with updated morphological data and distributional records

Abstract

The poorly known northeastern water skink Tropidophorus assamensis is only known from the type locality (Harigaj Range, Sylhet District) in Bangladesh, and few localities in Assam and Mizoram States, north-eastern India. Little is known about the biology including the systematics of the species. In this study, we present for the first time, genetic data (16s rRNA) and inferred its phylogenetic position. In addition to this, we provide updated morphological data along with new distributional records of the species from Mizoram State of north-east India.
