This species is endemic to the southern region of the Western Ghats in India at 400-1,800m asl.
Habitat and Ecology
It is associated with evergreen and semi-evergreen moist and deciduous forest, and is not found in agricultural areas. It is a semi-terrestrial frog that is largely found in the leaf-litter and also under rocks and logs. There is little information on its breeding biology, though breeding is presumably by larval development in streams.
The population is fragmented, and its status varies between localities.
The forest habitat of this species is being cleared for conversion to agricultural land (including tea plantations), and it is being exploited for timber and wood by local people. The construction of dams is also threat.
It has been recorded from Periyar Tiger Reserve, Silent Valley National Park, Parambikulam Wildlife Sanctuary and Neyar Wildlife Sanctuary, all in Kerala, and from Kalakad-Mundanthurai Tiger Reserve and Indira Ghandi National Park, both in Tamil Nadu. It is protected by national legislation.
