This species is known only from south-western and north-eastern Sarawak (Malaysia), but probably also occurs in western Kalimantan (Indonesia), in Borneo. It probably occurs more widely than current records suggest. It is present at elevations around 800m asl.
Habitat and Ecology
Males have been seen calling from low shrubs in submontane and montane mossy forest. Eggs are probably deposited in very small rain pools.
It is moderately abundant within its restricted range.
The major threat to the species is ongoing habitat loss due to agriculture and logging.
The species' range includes Gunung Mulu National Park and Lanjak Entimau Wildlife Sanctuary.
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 habitat on Borneo.
