This species is widespread in New Guinea from the Arfak Mountains (Vogelkop Peninsula) in the west (Indonesia) to the southeastern Peninsula of Papua New Guinea in the east, as far as Agaun in Milne Bay Province. It occurs from 500-2,000m asl.
Habitat and Ecology
It lives in vegetation along streams and small brooks in lowland and montane rainforest, and also occurs in disturbed habitats. It breeds in streams in which the younger larvae live. Old larvae are semi-terrestrial (Günther, 2006).
It occurs in large numbers wherever it is found.
Suitable habitat is extensive and no serious threats are known. Locally, pollution of streams from mining is taking place.
The taxonomy of these species complex needs must to be resolved. Given the declines of torrent-dwelling hylids in Australia, monitoring programs should be initiated. It occurs in several protected areas.
There is strong evidence that shows that Litoria arfakiana comprises more than one species (R. Guenther and S. Richards pers. comm.).
