This Bornean endemic occurs at a number of sites within Kinabalu National Park, and the Crocker Range south of Kinabalu in Sabah, in Gunung Mulu Park in Sarawak, and also in the montane forests of Kalimantan, including Kayan Mentarang National Park in East Kalimantan. It probably occurs more widely than current records suggest. Its altitudinal range is from 750-1,600 m asl.
Habitat and Ecology
Adults are found on the floor of submontane and montane forests. Breeding takes place in clear, rocky mountain streams. The larvae cling to rocks in the torrents of these streams. It appears to be unable to adapt to modified habitats.
It is abundant at most locations where it has been recorded.
The main threat to the species is siltation of streams needed for larval development, as a result of logging in the submontane and montane forests, and the clearance of forests for cultivation.
This species is known to be present in Kinabalu, Gunung Mulu and Kayan Mentarang National Parks.
Red List Status
Near Threatened (NT)
Listed as Near Threatened since although this species is still relatively widely distributed, it depends on streams in areas of undisturbed forest habitat, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat is declining very rapidly due to widespread forest loss within its range, thus making the species close to qualifying for Vulnerable.
