From the IUCN Red List Species Account:

 

Range Description

This species is known from several locations in the rugged mountains of eastern New Guinea, between Mount Kaindi and Mount Obree, Central Province, and Mount Simpson, Milne Bay Province, in Papua New Guinea. It has been collected from 1,280-2,480m asl. It likely occupies most of the Owen Stanley Range at appropriate elevations.

Habitat and Ecology

It lives along small (1-2m wide) streams in montane rainforest. Similar to other species in the genus, it probably lays eggs in streams where the tadpoles also develop.

Population

It is known to be common on the western slope of Mount Obree, Central Province, and on the eastern slope of Mount Simpson, in Milne Bay Province.

Population Trend

stable

Major Threats

Increased sedimentation in the streams due to mining is a localized threat. A road has also been built recently within its range. At Mount Simpson the species is utilized as a food item when it can be obtained. It is not known whether or not the current level of utilization is a threat.

Conservation Actions

Its distribution and abundance need to be properly documented. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated. Its range includes Mount Kaindi Wildlife Management Area.

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern since, although its currently known Extent of Occurrence is less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
