This species is known from three areas within submontane or montane sites in north-western Borneo (in Sabah and Sarawak (Malaysia) and in Brunei). It is present at elevations of 1,300-1,600m asl. It probably occurs a little more widely.
Habitat and Ecology
All three localities are within mossy montane forest. It is active at night, when temperatures are below 20°C, and males call from shrubs 1-4m above the ground. It is presumed to breed by direct development.
The population status of this species is unknown.
The known habitat of the species is fragmented and clear-cutting of the forest is a major threat.
It is known from a number of protected areas including Gunung Mulu National Park and Gunung Kinabalu National Park, both of which are World Heritage Sites. Continued effective protection of forests above 1,000m asl is essential for the conservation of this species.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its forest habitat in northwestern Borneo.
