This species is known from central Sarawak and adjacent Kalimantan, Borneo, below 300m asl. It is likely to occur a little more widely than current records suggest.
Habitat and Ecology
It lives in hilly lowland rainforest and breeds along small, clear, rocky streams. Larvae cling to the rocks in strong currents and feed on lithophytic algae. It appears to be unable to adapt to modified habitats.
It is a locally abundant species.
The principal threat to this species is habitat loss due to clear-cutting.
This species has been recorded from several protected areas, but more effective protection of lowland rainforest is needed.
