This Bornean endemic is known from western Sarawak, Malaysia and adjacent parts of west Kalimantan, Indonesia. It probably occurs more widely than current records suggest. It is a lowland species found from 100-500m asl.
Habitat and Ecology
It is restricted to closed-canopy hilly rainforest and does not occur in disturbed habitats. Adults and juveniles occupy the forest floor and shrub strata. Adults breed along the banks of clear, rocky streams and the larvae develop in the riffles of such streams.
There is no information on the current population status of this species.
The major threat is logging, which also results in increased siltation of forest streams and thereby poses a threat to larval habitat.
It is present in Lanjak Entimau Wildlife Sanctuary in central Sarawak. However, there is a need for more effective preservation and protection of lowland rainforest in western Kalimantan. Further survey work is needed to determine the current population status of the species.
Red List Status
Listed as Vulnerable, because its Extent of Occurrence is less than 20,000 km2 and its Area of Occupancy is less than 2,000 km2, its distribution is severely fragmented, and there is a continuing decline in the extent and quality of its forest habitat.
