This species is known only from Gunung Mulu in northern Sarawak, Borneo, Malaysia, at 1,800 m asl. It might occur in other montane forest blocks.
Habitat and Ecology
Specimens were observed calling beside a small, clear, mountain stream with a steep gradient. Males typically call from leaves of understorey vegetation, within steep water chutes and small channels of bedrock (Inger et al. 2017). Breeding by larval development is presumed to take place in these forest streams.
It is believed to be reasonably abundant.
This species is only known from Gunung Mulu National Park, which is well protected and not threatened at present (Y.M. Pui and I. Das pers. comm. March 2018).
The species has been recorded from Gunung Mulu National Park.
Continued management of Gunung Mulu National Park is necessary for the conservation of this species (Y.M. Pui and I. Das pers. comm. March 2018).
Further research is required on its ecology, and further survey work is needed to ascertain whether or not this species is indeed confined to Gunung Mulu. In any event, the population status of this species requires careful monitoring given that it is currently known from only a single location.
Red List Status
Listed as Least Concern because, although the distribution is limited, it occurs in a well-managed protected area for which there are no current threats and its population is thought to be stable.
