This species is restricted to two small areas of the southern Western Ghats of India in Kerala (Wayanad Wildlife Sanctuary and its surroundings) and Karnataka (Coorg and its surroundings) at an elevation of approximately 800m asl. It might occur a little more widely than current records suggest.
Habitat and Ecology
It inhabits tropical moist evergreen forest and deciduous forest, and has been recorded from secondary (disturbed) forest and coffee plantations (though this is not suitable habitat). An arboreal species, it is believed to occur in the lower canopy and understorey levels of the forest. Breeding takes place on vegetation overhanging small pools, and the larvae develop in these pools.
It is locally common.
It is threatened by the conversion of forest areas to cultivated land (including timber and non-timber plantations).
It has been recorded from the Wayanad Wildlife Sanctuary in Kerala, but remains unprotected in the remainder of its range. Further surveys to determine the full range of this recently rediscovered tree frog are urgently required.
Red List Status
Listed as Endangered, because its Extent of Occurrence of less than 5,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat in the Western Ghats of India.
