A new species of Rhinophis Hemprich, 1820 (Squamata, Uropeltidae) from Siruvani Hills, Western Ghats, India
We describe a new species of uropeltid snake of the genus Rhinophis based on a series of three specimens collected from the Siruvani Hills, which is part of the Central Western Ghats in Kerala and Tamil Nadu states of Peninsular India. Rhinophis siruvaniensis sp. nov. is diagnosed from other Indian and Sri Lankan congeners by a combination of 17 dorsal scale rows at (or well beyond) mid-body, 202–205 ventral scales, 4–8 paired subcaudals, and dark brownish-black dorsal and pale whitish blotched lateral and ventral colouration. Phylogenetic reconstructions using mitochondrial markers indicate that the new species is most closely related to R. melanoleucus, but the two species can be distinguished by their unique external morphology and geographic separation. The discovery of this species from outside protected areas in the Attappadi Plateau highlights the need for improved protection of the remaining forests in the Siruvani Hills.
