This species is known only from the type locality of "Hatam sul Monte Arfak", in the Arfak Mountains, Vogelkop Peninsula, Papua, Indonesia.
Habitat and Ecology
It is a montane species that presumably lives in streams in tropical rainforest. If it is similar to other species in the genus, it lays large eggs in torrential, clear and rocky streams, and the larvae have large suckers.
No data are available on its population status, and there are no known records since it was first described, although there have been no subsequent surveys of the area.
The threats to this species are unknown.
Its type locality is within Arfak Mountains National Park. Given the declines of torrent-dwelling hylids in Australia, the population status of this species requires close monitoring.
Red List Status
Data Deficient (DD)
