This species is known from a small area of the eastern Star Mountains in the vicinity of the type locality (Telefomin, West Sepik Province, Papua New Guinea), and from an area 30km to the west. It has been recorded at about 1,750m asl. Although it is probably more widely distributed, no data are available to support this view at this stage.
Habitat and Ecology
This species occurs in torrential streams in rainforest. If it is similar to other species in the genus, it lays large eggs in torrential, clear and rocky streams, and the larvae have large suckers.
Its population status is unknown.
There are no known threats to this species, and there are not thought to be any specific threats to its habitat at present.
Given the declines of torrent-dwelling hylids in Australia, the population status of this species requires close monitoring.
