This widespread Bornean endemic is present in relatively steep terrain from 150-1,500m asl.
Habitat and Ecology
Adults can be found on the floor and herb stratum of rainforests. It requires small, clear, rocky-bottomed streams to breed in, an environment that persists only where forest cover is intact. Larvae live in torrents, clinging to rocks and feeding on lithophytes. This species is unable to adapt to modified habitats.
It is known to be abundant at several localities.
The main threat is rampant habitat loss due to the rapid clearing of forest in Borneo, and the subsequent siltation of streams.
This species is known to occur in several protected areas, including in Sabah and Sarawak. However, in Kalimantan, the existing forest preserves and parks are not well protected.
