From the IUCN Red List Species Account:


Range Description

This Bornean endemic is known only from the montane forests of Kinabalu, Malaysia. Attempts to locate the species on Gunung Mulu in Sarawak have not been successful. The altitudinal range is 1,500-3,050m asl.

Habitat and Ecology

Most records are from moist montane and sub-alpine forest above 2,500m asl. Adults are terrestrial, and breeding is presumed to take place in forest streams.


The current population status of this species is unknown. It is rarely encountered.

Population Trend


Major Threats

The major threat to this species in the future is likely to be selective logging.

Conservation Actions

It occurs in Kinabalu National Park, which is well protected. Surveys of potentially suitable areas of habitat in adjacent parts of Borneo are needed to determine whether or not this species might occur elsewhere, and also to help better understand its current population status.

Red List Status

Vulnerable (VU)


Listed as Vulnerable because it is known from fewer than five locations.

Taxonomic Notes

We follow Inger (1966) and Malkmus et al. (2002) in considering Ansonia altitudinis (Smith 1931) to be a synonym of A. fuliginea.
