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.
