From the IUCN Red List Species Account:

 

Range Description

This species has been found at many localities in north-western Borneo, from 65-1,200m asl. It was also recorded once in Lampung, Sumatra, but its distribution here is still questionable. It is likely to occur a little more widely than current records suggest.

Habitat and Ecology

This is a largely aquatic species, most often seen in seepage areas in primary lowland rainforest. Larvae also develop in these thin films of water. This species appears to be unable to adapt to modified habitats.

Population

The population status of this species is unknown.

Population Trend

decreasing

Major Threats

The major threat is habitat loss due to clear-cutting.

Conservation Actions

It is present in a number of protected areas in Borneo, and the Sumatran specimens were collected in a protected area. The preservation of lowland tropical moist forest in Borneo is recommended as a conservation measure for this species.

Red List Status

Near Threatened (NT)

Rationale

Listed as Near Threatened since although this species is still relatively widely distributed, it depends on areas of undisturbed forest habitat, and so its Extent of Occurrence is probably not much greater than 20,000 km2, and the extent and quality of its habitat is declining very rapidly due to widespread forest loss within its range, thus making the species close to qualifying for Vulnerable.

Taxonomic Notes

A taxonomic review of the specimens assigned to this taxon (especially those of Sumatran origin) is recommended.
