From the IUCN Red List Species Account:


Range Description

This species is relatively widespread over the rugged highlands of the Huon Peninsula and central Papua New Guinea, at 1,200-2,000m asl.

Habitat and Ecology

It lives in streams in montane rainforest. This species lays large eggs in torrential streams. The tadpoles have large suckers. It has only been found in mature forest.


It is common where it is found.

Population Trend


Major Threats

No threats are known. It lives in very remote areas.

Conservation Actions

Its distribution needs to be properly documented, as well as the taxonomic status of different populations. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated. It has been found in the Crater Wildlife Management Area.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its Extent of Occurrence is probably not much greater than 20,000 km2, it has a presumed large population, much suitable habitat is still intact, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
