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.

Population [top]

Population: It is known to be abundant at several localities.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Adults can be found on the floor and herb stratum of rainforests. It requires small, clear, rocky-bottomed streams to breed in, an environment that persists only where forest cover is intact. Larvae live in torrents, clinging to rocks and feeding on lithophytes. This species is unable to adapt to modified habitats.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): The main threat is rampant habitat loss due to the rapid clearing of forest in Borneo, and the subsequent siltation of streams.

Conservation Actions [top]

Conservation Actions: This species is known to occur in several protected areas, including in Sabah and Sarawak. However, in Kalimantan, the existing forest preserves and parks are not well protected.
