This species has been found only in the Indonesian part of Borneo, below 300 m asl. It is likely to occur more widely than current records suggest.
Habitat and Ecology
It is known only from the floor of lowland rainforests, where it is associated with slow-flowing streams in which it is likely to breed by larval development.
There is little information on its population, but it is suspected to be decreasing due to ongoing decline in the quality and extent of its habitat.
The principal threat to the species is rapid clear-cutting of lowland tropical rainforest in forest concession land and for oil palm plantations (Indonesia Red List Assessment Workshop May 2017).
The species is known from Kayan Mentarang National Park, Bukit Baka Bukit Raya National Park and Gunung Tarak Protected Forest.
Effective preservation of lowland forest is needed to conserve this species because oil palm plantations are encroaching into protected areas. Some oil palm companies and forestry companies designate High Conservation Value areas, which is required by some financial institutions providing loans. However, not all lenders require these areas to be set aside and the habitat within the HCVs could disappear if the lender or requirements change (Indonesia Red List Assessment Workshop May 2017).
More information is needed on this species distribution, population status and trends, and threats.
Red List Status
Near Threatened (NT)
Listed as Least Concern in view of its wide distribution and presumed large population.
