This species is relatively widespread over the rugged highlands of the Huon Peninsula and central Papua New Guinea, at 1,200-2,000m asl.
Habitat and Ecology
It lives in streams in montane rainforest. This species lays large eggs in torrential streams. The tadpoles have large suckers. It has only been found in mature forest.
It is common where it is found.
No threats are known. It lives in very remote areas.
Its distribution needs to be properly documented, as well as the taxonomic status of different populations. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated. It has been found in the Crater Wildlife Management Area.
