This species is known only from a single specimen from the type locality, Gapaia Creek, between Garaina and Saureli, Morobe Province, Papua New Guinea, which is about 1,280 m asl. It is likely to have a relatively broad distribution in suitable habitats but additional data are needed.
Habitat and Ecology
It occurs in torrential mountain streams in rainforest. If it is similar to other members of the genus, this species lays large eggs in torrential streams and has larvae with large suckers.
Only one specimen is known, so its population status cannot be determined.
The area from which it has been recorded is remote and is probably safe from most threats.
Given the declines of torrent-dwelling hylids in Australia, the population status of this species requires close monitoring.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
