This species is widespread in the mountains of central and eastern New Guinea. It occurs from 850-1,600m asl.
Habitat and Ecology
It lives in streams in tropical rainforest. Similar to other species in the genus, it presumably lays large eggs in torrential, clear and rocky streams and the tadpoles presumably have large suckers.
It is not a common species, and is only rarely encountered.
There are probably no threats to this species at present; its habitat appears quite secure.
Its distribution and abundance need to be properly documented. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated. It occurs within the Crater Wildlife Management Area.
