As it is currently recognized, this species is widespread in the mountains of central and eastern mainland New Guinea (in Indonesia and Papua New Guinea) and is also known from Goodenough and Fergusson Islands, from 300-1,600m asl.
Habitat and Ecology
It lives in and around small streams in lowland and montane rainforest (hill forest). It breeds in streams, and also occurs in degraded forests and rural gardens.
It appears to be abundant throughout its range.
No threats are known.
The taxonomic status of population at the type locality needs to be assessed, and there should be better documentation of its distribution. Given declines of torrent-dwelling hylids in Australia, monitoring programmes should be initiated. It can be found in Crater Wildlife Management Area, and probably in other protected areas.
The status of populations in Papua New Guinea is unclear. More than one species might be included in this taxon (S. Richards pers. comm.).
