This species is known from central Sarawak (Malaysia) and central Kalimantan (Indonesia), Borneo. It probably occurs 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 is a locally abundant species.
The principal threat to this species is habitat loss due to clear-cutting.
It has been recorded from Lanjak Entimau Wildlife Sanctuary and Betung-Kerikum National Park. More effective protection of large areas of rainforest is needed.
