This species is presently known only from four localities, largely in the Western Ghats in southern India - the type locality of Thrissur (Kerala), Eravikulam National Park (Kerala), Palni Hills (Tamil Nadu) and Upper Bhavani (in Mukurthi National Park, Tamil Nadu) (Pradhan and Kurup 2001; Shankar 1998). The 19th century type locality is from Trissur, Kerala state, southern India - this is near sea level and may not be the exact type locality (Molur et al. 2005). It has been recorded from 1,500 to 2,500 m asl.
