Geographic Range [top]

Range Description:This Bornean endemic occurs at a number of sites in and around Kinabalu National Park and Crocker Range in Sabah, in Gunung Mulu National Park in Sarawak, and 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 500–1,600 m asl.
Countries occurrence:
Indonesia (Kalimantan); Malaysia (Sabah, Sarawak)
Additional data:
Lower elevation limit (metres):500
Upper elevation limit (metres):1600

Population [top]

Population:It is abundant and common at most locations where it has been recorded. It is commonly observed during surveys in Crocker Range and Kinabulu National Park, as well as, outside of these parks, where suitable habitat occurs (P. Yambun pers. comm. January 2018). There is some localised habitat loss occurring within Indonesia that may be causing some local declines, however the population is considered to be relatively stable in Malaysia.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

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 and the larvae cling to rocks in the torrents of these streams. The species requires good water quality (P. Yambun pers. comm. January 2018).
Systems:Terrestrial; Freshwater
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade:

There are no records of this species being utilized.

Threats [top]

Major Threat(s): The main potential threat to the species is siltation of streams needed for larval development, as a result of logging in the submontane and montane forests. There are no threats to this species in Sabah, as it occurs in two well-protected and well-managed national parks (P. Yambun pers. comm. January 2018). The subpopulation in Sarawak is within Gunung Mulu National Park, which is well protected and not threatened at present (Y.M. Pui pers. comm. March 2018).

Conservation Actions [top]

Conservation Actions: Conservation Actions
This species is known to be present in Kinabalu, Crocker Range, Gunung Mulu and Kayan Mentarang National Parks.

Research Needed
Further work is required to improve the understanding of the species' population size, distribution and trends.
