This Bornean endemic is known only from a few localities in western and central Sarawak (Malaysia) and scattered areas of Kalimantan (Indonesia), although it probably occurs more widely than current records suggest. All known localities lie between 200 and 1,000m asl.
Habitat and Ecology
This is a terrestrial species of lowland moist tropical forest, which breeds in small, clear, rocky streams where the larvae also develop. It has not been found in modified habitats.
There is no information on its population status.
The main threat to this species is habitat loss and fragmentation largely due to the effects of extensive logging on lowland Borneo.
This species is known from the Kayan Mentarang protected area and continued protection of large areas of hilly rainforest is needed.
