From the IUCN Red List Species Account:


Range Description

This species ranges along the mountainous ridge of northwestern Borneo, in Sabah and Sarawak, Malaysia. It occurs at elevations between 1,200–2,200 m asl. It is likely to occur more widely throughout the Central Mountain Range (I. Das pers. comm. March 2018).

Habitat and Ecology

This species occurs in submontane and montane forests. Males gather at small ponds in which the larvae develop, in or at the edge of these forests. It will tolerate some habitat disturbance as evidenced by observations of it in an artificial pond in Sarawak, however it will not tolerate the removal of its forest habitat (I. Das pers. comm. March 2018).


It is locally abundant in Crocker Range and Kinabalu National Park (P. Yambun pers. comm. January 2018). It is common and abundant in Sarawak (I. Das pers. comm. March 2018). Its population is considered to be stable.

Population Trend


Major Threats

There are no threats to the species in Sabah, as its forest habitat is well protected within two national parks (P. Yambun pers. comm. January 2018). The subpopulation within Gunung Mulu National Park is well protected and not threatened at present (Y.M. Pui and I. Das pers. comm. March 2018). The subpopulation at Gunung Murud is within the recently gazetted Pulong Tau National Park, however this area is subject to subsistence logging (I. Das pers. comm. March 2018).

Conservation Actions

Conservation Actions
It has been recorded from Kinabalu, Crocker Range, and Gunung Mulu National Parks.

Conservation Needed
Continued management of the protected areas where this species occurs in Sabah and Sarawak is necessary for the conservation of this species.

Research Needed
Further research on this species' distribution, population size and trends is recommended.

Red List Status

Near Threatened (NT)


Listed as Least Concern in view of its relatively wide distribution, tolerance of a degree of habitat modification, and presumed large population.
