From the IUCN Red List Species Account:

 

Range Description

This species is known only from northern and western Borneo. It probably occurs more widely than current records suggest, especially in areas between known sites. It is present at altitudes of 100-900m asl.

Habitat and Ecology

It is known only from lowland and mid-elevation primary rainforests where it has been found in the floor litter and along stream banks. It probably breeds on land by direct development, like other members of its genus.

Population

No subpopulation size estimates have been made. At one or two localities it seems to be relatively common.

Population Trend

decreasing

Major Threats

Deforestation is the most serious threat to this species.

Conservation Actions

The species is present in at least five protected areas. More needs to be learned of breeding habits and subpopulation sizes.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Taxonomic Notes

This species probably does not belong in the genus Ingerana. It should probably be assigned to a new genus in the family Ceratobatrachidae, but we retain it in the genus Ingerana in the Dicroglossidae, pending resolution of this problem. We follow Inger and Tan (1996) in considering Ingerana sariba to be a synonym of this species.
