This species is endemic to Great Nicobar Island (of the southern portion of the Andaman and Nicobar Islands), India, where it has been recorded from at least three separate localities at elevations up to 500m asl.
Habitat and Ecology
It is an arboreal species of tropical moist forest. Specimens have been collected in low shrubs and in puddles away from riparian vegetation. It is presumed to breed in temporary pools.
Reports from 1994-1997 indicate that the species appears to be reasonably abundant on the island (R. Daniels pers. comm.), although there are no quantitative data to support this.
The major threat is habitat loss due to intensive crop production and human settlement.
It occurs in the Galathea Biosphere Reserve on Great Nicobar Island. Survey work is needed to obtain a better understanding of the current population status of this species.
Red List Status
Listed as Endangered, because its Extent of Occurrence of less than 5,000 km2 and its Area of Occupancy is less than 500 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.
