Justification: 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. |

Geographic Range [top]
| Range Description: | 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. |

| Population Trend: |
Stable
|
Habitat and Ecology [top]
| 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. |
| Systems: | Terrestrial; Freshwater |
Threats [top]
| Major Threat(s): | 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. |
Conservation Actions [top]
| Conservation Actions: | This species is known to be present in Kinabalu, Gunung Mulu and Kayan Mentarang National Parks. |
