A new species of bent-toed geckos of the genus Cyrtodactylus is described from western Arunachal Pradesh. The new species is a member of the Indo-Burma clade and is embedded within the `peguensis" group, a relationship deduced contingent on a partial fragment of mitochondrial NADH subunit 2 gene. Cyrtodactylus kamengensis sp. nov. is morphologically similar to C. himalayicus from which it differs in bearing a distinct ventrolateral fold and 6-8 basal lamellae on digit IV of pes. Genetically, the new species is sister to the Indian lineage of the `peguensis" group containing C. bhupathyi and C. gubernatoris. The Indian lineage of the `peguen-sis" group diverged from its Burmese relatives during the mid-Oligocene likely followed by the beginning of the Himalayan uplift, highlighting the role of the Himalayas in the diversification of biota.
