This species is endemic to the Western Ghats of India. It has an altitudinal range of 400-1,400 m asl.
Habitat and Ecology
It is associated with rocky streams within moist evergreen tropical forest, and it can be found at forest edges and in slightly disturbed forest. Individuals are diurnal and are often found attached to vertical surfaces of wet rocks in fast flowing streams (Krishna and Krishna 2006).
Breeding takes place in streams by larval development.
It is a locally abundant species (Krishna and Krishna 2006).
It is threatened by commercial deforestation (clear-cutting) of its forest habitat, the modification of waterways (through dam construction), and the construction of human settlements. It is possible that these threats, especially deforestation, have significantly increased levels of stream sedimentation.
It has been recorded from Nilgiri Biosphere Reserve (in Kerala and Tamil Nadu), Kalakad-Mundanthurai Tiger Reserve (in Tamil Nadu), and Kudremukh National Park (in Karnataka). The species is included as part of ongoing field studies by Addoor in Karnataka (1997 and onwards). It is protected by national legislation.
Red List Status
Listed as Vulnerable because its extent of occurrence is less than 20,000 km², its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat.
