This species is known only from the central hilly regions of Borneo, below 500m asl. It is likely to occur more widely than currently recorded.
Habitat and Ecology
It is known only from the banks of clear, rocky streams in hilly lowland primary rainforest. Juveniles and adults do not disperse from the immediate vicinity of such streams and the larvae develop in pools along those streams.
It is considered to be locally abundant. A density of 20-60 individuals per 600m of stream length was estimated at one site in Sarawak surveyed in 1962-63.
The main threat to this species is deforestation arising from clear-cutting. As it is quite large, local people often hunt this species for food, and its long life cycle and small clutch size make it particularly vulnerable to overharvesting.
It is present in at least three protected areas, although more effective protection of areas of hilly, lowland rainforest in Sarawak and Kalimantan is needed.
