From the IUCN Red List Species Account:


Range Description

This Bornean endemic is widely distributed in relatively steep terrain in Malaysia and Indonesia, from 150-750m asl.

Habitat and Ecology

Adults disperse widely over the floor and herb stratum of rainforest. It requires small, clear, rocky-bottomed streams to breed in, and larvae live in torrents, clinging to rocks and feeding on lithophytes. It appears to be unable to adapt to modified habitats.


It appears to be abundant at scattered lowland localities.

Population Trend


Major Threats

The main threat to the species is deforestation of large portions of the habitat, with the resultant loss of adult and juvenile (through the siltation of streams) feeding microhabitats. Conversion of forest to oil palm plantations is also a threat and it is possible that a broad portion of its range might soon be converted to Acacia plantations.

Conservation Actions

The species is known from several protected areas, including Kinabalu National Park, which is in Sabah, where good, large areas of forest are now protected, as are some sites in Sarawak. The species might well occur in Kalimantan but existing forest preserves and parks are not well protected. Further protection of large areas of rainforest is needed.
