This species is relatively widespread in the Western Ghats, India, from 400-900m asl. Dutta (1997) lists uncertain records from the Eastern Ghats, which require further verification.
Habitat and Ecology
It is a terrestrial toad associated with leaf-litter, rocks and other ground cover of moist tropical evergreen and semi-evergreen forest. It is not known if it can occur in degraded habitat. Breeding takes place in slow-moving stretches of streams.
It is a locally common species.
The main threat to this species is deforestation caused by both regional infrastructure development (roads, dams, and urbanization) and the collection of wood and timber for subsistence use by local people.
It has been recorded from Indira Gandhi National Park (in Tamil Nadu), Agasthyamala Hills of the Neyar Wildlife Sanctuary, Silent Valley National Park (both in Kerala), and might also occur within other protected areas in the region.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because its Extent of Occurrence is probably not much greater than 20,000 km2, and the extent and quality of its habitat are probably declining, thus making the species close to qualifying for Vulnerable.
