This species is known only from two localities in the upper Sepik drainage of northern Papua New Guinea. It probably occurs throughout this mountainous region but further data on its distribution are required. It occurs around 1,600m asl.
Habitat and Ecology
This species lives in and around small streams in montane rainforest, and probably breeds in torrential mountain streams.
It was rediscovered in 1993 on Mount Stolle, Sandaun Province, where it is reasonably common.
There are no known threats to this species, which occurs in a very remote area.
It occurs on a mountain where local communities are providing some habitat protection. Given the declines of torrent-dwelling hylids in Australia, the population status of this species requires close monitoring.
