Abstract

ABSTRACT: A new species of Cyrtodactylus is described herein on the basis of morphological and phylogenetic evidence inferred from the mitochondrial nicotinamide adenine dinucleotide hydride dehydrogenase subunit 2 gene from Mizoram, Northeast India. The new species is distinguished from its congeners by an adult snout-vent length of 62.6–68.6 mm; 10–11 supralabials; 9–11 infralabials; dorsal tubercles rounded, conical to weakly keeled and in 19–20 longitudinal rows; 32–36 paravertebral tubercles between the level of axilla and groin; 32–39 mid-ventral scale rows across the ventral region; 6 precloacal pores in males and 0–6 precloacal pits in females; 14–18 subdigital lamellae under toe IV; no single row of transversely enlarged subcaudal scales; indistinct pattern of alternating dark brown blotches on the dorsum of the body. Morphologically and genetically, the new species is recovered as the sister species to C. aaronbaueri, but is genetically distinct by an uncorrected p -distance of 0.099–0.1, and morphologically in the number of precloacal pores, mid-ventral scale rows, paravertebral tubercles on the trunk, dorsal tubercle rows, dorsal spot, and subdigital lamellae on pes. http://www.zoobank.org/urn:lsid:zoobank.org:pub:8E9144FA-EFAF-4C7D-B64F-667706643EC5
