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. |
|
| Range Description: | This species is endemic to Borneo where it is known from several widely scattered localities across the northern part of the island, in relatively steep terrain, at altitudes of 150-350m asl. |

| Population: | It appears to be abundant in a few places, although in general the population is decreasing in direct proportion to rates of deforestation. |
| Population Trend: |
Decreasing
|
| Habitat and Ecology: | The adults of this species are mostly terrestrial and disperse widely over the rainforest floor. Breeding takes place in small, clear, rocky-bottomed streams. The larvae live in torrents, clinging to rocks and feeding on lithophytes. This species appears to be unable to adapt to modified habitats. |
| Systems: | Terrestrial; Freshwater |
| Major Threat(s): | The major threat is forest loss and fragmentation, due to the conversion of forests to rubber and oil palm plantations, as well as the resulting eutrophication of streams by chemical fertilisers and stream siltation (thereby depriving larvae of feeding sites). |
| Conservation Actions: | It is present in several protected areas, and the continued protection of large areas of hilly rainforests is essential. |
