This species occurs in Borneo (Brunei and Sarawak) below 1,000m asl. It is assumed to occur across the border into Kalimantan although there are no records from there yet.
Habitat and Ecology
It has been recorded only from lowland tropical moist forest. Breeding is presumed to take place in small forest pools.
Its population status is unknown.
The major threat to this species is habitat loss and fragmentation due to deforestation.
The presence of this species in protected areas requires further investigation. Some areas of habitat are protected in Sarawak.
Red List Status
Near Threatened (NT)
Listed as Near Threatened since although this species is still relatively widely distributed, it depends on areas of undisturbed forest habitat, and so its Extent of Occurrence is probably not much greater than 20,000 km2, and the extent and quality of its habitat is declining very rapidly due to widespread forest loss within its range, thus making the species close to qualifying for Vulnerable.
Specimens from the Malay Peninsula and the Natura Islands previously included in Pelophryne signata are now assigned to P. brevipes.
