This species is known only from Gunung Mulu in northern Sarawak, Borneo, Malaysia, at 1,800m asl, though it is possible that 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. Breeding is presumed to take place in these forest streams.
It is believed to be reasonably abundant.
There are no current major threats to this species, but if Gunung Mulu is indeed the only locality at which this species occurs, then it might well be susceptible to stochastic threatening processes.
The species has been recorded from Gunung Mulu National Park. 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 Vulnerable because it is known from only a single location.
