From the IUCN Red List Species Account:


Range Description

This species is found only in the general Sinharaja region of south-western Sri Lanka from 150-660m asl. There are records from Sinharaja, Morawaka and Deniyaya (Manamendra-Arachchi and Pethiyagoda 2005).

Habitat and Ecology

It lives on the ground in leaf-litter, in damp shaded closed-canopy rainforest habitats. At night, males perch and vocalize from branches and leaves around 0.3m above ground (Manamendra-Arachchi and Pethiyagoda 2005). It is a direct developer and is not dependent on water.


It is a common species.

Population Trend


Major Threats

It is largely restricted to protected forests, and hence its habitat is generally well protected at present. However, it is probably impacted by firewood collecting and illegal gemstone mining.

Conservation Actions

It is found in the Sinharaja World Heritage Site, the largest remnant of Sri Lanka's forests, which was inscribed in 1988.

Red List Status

Endangered (EN)


Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, and its Area of Occupancy is less than 500 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in southwestern Sri Lanka.
