This species is endemic to the southern region of the Western Ghats of India, where it has been recorded from the Ponmudi Hills and Wayanad Wildlife Sanctuary, both in Kerala. Unpublished reports of this species outside Kerala require confirmation and hence are not mapped here, although it probably occurs more widely than current records suggest. It has an altitudinal range of 300-1,150m asl.
Habitat and Ecology
It is semi-aquatic and has been recorded from riparian habitats and hill streams in tropical moist evergreen forest; it may be found at the forest edge, but not in heavily cultivated land. There is little information on its breeding habitats, though breeding presumably takes place by larval development in streams.
It is an uncommon species.
The major threat is the conversion of forest habitat to agricultural land and plantations (tea and coffee).
It has been reported from Wayanad Wildlife Sanctuary, and is protected by national legislation.
