This species is endemic to the Western Ghats of India, where it has a very fragmented range. It occurs at elevations of 300-1,800m asl.
Habitat and Ecology
It is a semi-arboreal species generally associated with montane moist evergreen forest. Breeding takes place on the ground at stream banks, and the larvae develop in water.
There is no reliable information available on the population status of this species, although it is locally uncommon and believed to be declining.
It is threatened by the conversion of its forest habitat to non-timber plantations (including coffee and tea), the collection of timber and wood for subsistence use by local people, and the construction of roads and dams.
It has been recorded from several protected areas, including the Konya Wild Life Sanctuary (Maharashtra), Cotigao Wild Life Sanctuary (Goa), Indira Ghandi National Park and Kalakad-Mundanthurai Tiger Reserve (Tamil Nadu), Ponmudi Hills and Silent Valley National Park (Kerala). The species is the focus of ongoing studies from 1998 to the present (S. D. Biju pers. comm.).
