This species is known only from western Sabah and east-central Sarawak in Malaysian Borneo at elevations of 200-700m asl. It probably occurs more widely than current records suggest.
Habitat and Ecology
It is known only from primary, hilly, lowland rainforest. Adults and juveniles live on the forest floor. Breeding presumably takes place in small, clear streams as with other species of the genus.
It does not appear to be common or abundant at any site.
The major threat is the loss of habitat through clear-cutting, and most suitable lowland habitat in Sabah has now been logged.
The species exists in protected areas in Sabah, but remains unprotected in Sarawak. There is an urgent need for the protection of remaining suitable lowland forest habitats at sites where this species is known to occur.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in Sabah and Sarawak, Borneo.
