This species is known from the mountains of Papua, Indonesia: the type locality in the Snow Mountains, and two locations in the Wapoga River headwaters (where the species was found in 1998). There was one specimen-collected 40km southeast of Nabire in Papua. It has been recorded between about 500-1,000m asl.
Habitat and Ecology
This species inhabits torrential streams in rainforest It lays unpigmented eggs near the streams.
It was quite abundant when collected at Wapoga River.
There are no threats to this species as it is in a very remote area. The species is presumably secure, but data are lacking.
Further documentation of the species' distribution is needed. It is not known from any protected areas. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated.
Red List Status
Least Concern (LC)
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.
