From the IUCN Red List Species Account:


Range Description

This species was collected in the Kelabit Highlands of Sarawak, Malaysia, at "Long Re (03° 42' 02"N; 115° 32' 06"E), east of Bario along [the] forest trail to [the] Kalimantan border" (Das and Haas 2003). It was collected at an altitude of around 1,050m asl.

Habitat and Ecology

It was found calling from a water-filled node of a bamboo plant that had fallen across a forest path within primary submontane forest, following a night of torrential rainfall. Its breeding habitats are unknown, but this species may breed in these water pools at the internodes of bamboo plants.


It is known only from the holotype, so its population status is not known.

Population Trend


Major Threats

The whole of the Kelabit Highlands, where the holotype was collected, are threatened by commercial logging (presumably both clear-cutting and selective logging). The type of bamboo in which this species was found is harvested by local people for subsistence use.

Conservation Actions

This species was not collected in a protected area.

Red List Status

Data Deficient (DD)


Listed as Data Deficient since it has only recently been described, and there is still very little information on its extent of occurrence, status and ecological requirements.
