A new species of the uropeltid snake genus Uropeltis Cuvier, 1829 is described from the environs of Munnar in the Anamalai hils of the Western Ghats of peninsular India. Uropeltis tricuspida sp. nov. superficially resembles the poorly known and closely related U. petersi, but differs from that species in having more ventral and subcaudal scales, and a tri- rather than bicuspid posterior tip to the terminal scute.
