From the IUCN Red List Species Account:


Range Description

This species is known from only two localities in Papua, northwestern New Guinea, Indonesia, at about 600m asl. It probably occurs in suitable habitat between these localities.

Habitat and Ecology

It lives in streams in tropical rainforest. If it is similar to other species in the genus, it presumably lays large eggs in torrential, clear and rocky streams and the larvae have large suckers.


It was last recorded in 1998 (Richards et. al. 2000), and is known from only two specimens, one from each locality.

Population Trend


Major Threats

There are no known threats to this species.

Conservation Actions

Given the declines of torrent-dwelling hylids in Australia, the population status of this species requires close monitoring.

Red List Status

Data Deficient (DD)


Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements.
