This species is known from a number of localities in rugged mountain habitats of eastern Papua New Guinea. Its altitudinal range is 850-1,500m.
Habitat and Ecology
It lives in and around torrential streams in rainforest. It appears to be tolerant of at least some level of habitat degradation, and can be found in rural gardens. It breeds in streams, including silted streams.
Its abundance ranges from uncommon to reasonably common.
None are known. It is adaptable and occurs in remote areas where there is little human pressure.
There should be further documentation of its distribution. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated. It is found in Crater Wildlife Management Area.
Red List Status
Least Concern (LC)
Listed as Least Concern because, although its currently known Extent of Occurrence is less than 5,000 km2, it is common, adaptable, and does not appear to be in decline.
