Calliophis castoe

Castoe's coral snake is a venomous elapid endemic to the Western Ghats of western peninsular India, found in semi-evergreen and wet forests in the central Western Ghats across Maharashtra, Goa and Karnataka. Adult males measure 536–540 mm in total length (Wikipedia, general species account).

Dark specimens collected earlier by Phipson and Wall as the black coral snake from places where this species occurs have since been identified as Castoe's coral snake. One such specimen was collected by Vidal at Karwar in 1887.
