This species is widespread in the mountains of New Guinea from the Vogelkop Peninsula in the west (Indonesia) to the southeast peninsula of Papua New Guinea. It has also been recorded from Yapen Island (Indonesia) and Goodenough, Fergusson and Normanby Island in the D'Entrecasteaux Islands (Papua New Guinea). It occurs from about 100m up to 1,800m asl.
Habitat and Ecology
This species inhabits and breeds in fast- or moderately flowing streams in tropical rainforest, rural gardens, villages, and degraded habitats.
It is an abundant species.
It is not threatened, though it is captured for food by local human communities.
The taxonomic status of this species needs to be assessed. It occurs in some protected areas.
This name is currently used for a complex of more than one species of frog which collectively range widely in the mountains of New Guinea (Kraus and Allison, 2007). True Hylarana supragrisea occurs in the southeast of New Guinea, including the D'Entrecasteaux Islands, but its distributional limits are uncertain (Kraus and Allison, 2007). In this account we continue to use this name for the whole complex, pending resolution of these taxonomic issues.
