From the IUCN Red List Species Account:


Range Description

This species is known with certainty only from the type locality of "Camp VIa, Utakwa [or Octakwa] River, 3000 ft", Papua, Indonesia. The altitude of this locality is 914m asl. A specimen in the South Australian Museum from the Star Mountains in Papua New Guinea might represent a significant range extension, but further studies are required to confirm the identity of this specimen.

Habitat and Ecology

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


This species has not been recorded again since it was first described, so its population status is unknown. A recent visit to the area failed to find it, but the survey was not exhaustive.

Population Trend


Major Threats

The threats to this species are unknown.

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 the absence of recent information on its extent of occurrence, status and ecological requirements.
