From the IUCN Red List Species Account:


Range Description

This species is widespread in the mountains of central and eastern New Guinea. It occurs from 850-1,600m asl.

Habitat and Ecology

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


It is not a common species, and is only rarely encountered.

Population Trend


Major Threats

There are probably no threats to this species at present; its habitat appears quite secure.

Conservation Actions

Its distribution and abundance need to be properly documented. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated. It occurs within the Crater Wildlife Management Area.

Red List Status

Least Concern (LC)


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.
