From the IUCN Red List Species Account:


Range Description

This species is endemic to central Sri Lanka, and occurs in two disjunctive populations, one in the Central Hill Country, and the other in the Knuckles Range. It has been recorded at 1,250-1,300m asl. There are records from Perediniya, Agra-Bopath, Bogowantalawa, and the Knuckles Range (Manamendra-Arachchi and Pethiyagoda 2005).

Habitat and Ecology

It lives in both closed and open canopy rainforest, where it has been found at night on boulders and branches near streams. During the day, it hides in rock crevices on the margins of streams. It has not been found away from forest (Manamendra-Arachchi and Pethiyagoda 2005). Breeding presumably is by direct development. The female excavates a deep hole in the forest floor where the eggs are then deposited.


It appears to be an uncommon species.

Population Trend


Major Threats

It is probably affected by habitat loss due to farming (cultivation of cardamom and tea), collection of firewood, timber extraction and plantations (pine), and expanding human settlements, as well as pollution by agro-chemicals (resulting in deterioration of water quality).

Conservation Actions

It occurs in the Knuckles Forest Reserve and the Peak Wilderness Sanctuary.

Red List Status

Endangered (EN)


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 in central Sri Lanka.

Taxonomic Notes

We consider this species to be distinct from Philautus nanus (G√ľnther, 1858) following Manamendra-Arachchi and Pethiyagoda (2005).
