Abstract

A new species of Cyrtodactylus is described from Vairengte town, situated in the Kolasib District of Mizoram State, north-eastern India. The new species is found to be a member of Indo-Burman Cyrtodactylus khasiensis clade based on ND2 gene sequences and morphological parameters, such as number of precloacal pores, mid-ventral scale rows, paravertebral tubercles on the trunk, dorsal tubercle rows, subdigital lamellae on pes and subcaudal scalation, making it the sixth endemic Cyrtodactylus from Mizoram and twenty second from north-east India. Moreover, phylogenetic evidence suggests the new species to be sister to the recently described C. aaronbaueri, and morphological analyses also reveal marginal separation between the two species based on the PCA of infralabials, lamellae on fingers and toes, paravertebral tubercles on the trunk, and dorsal tubercle rows.
