This recently described species is distributed in the Adelbert Mountains and adjacent coastal region of Madang Province, Papua New Guinea, westward to the south slope of the Schrader Mountains, and probably northwest as far as the vicinity of Lumi, West Sepik Province. It has an altitudinal range of 0-975m asl.
Habitat and Ecology
This species is presumed to occur in tropical rainforest. Animals were found perched in vegetation up to 5m above ground. Like other species in the genus, it presumably breeds by direct development. It is not known if it can adapt to modified habitats.
There is no information available on the population status of this species.
The threats to this species are not known.
It is not known if the species is present in any protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
Specimens from East Sepik and West Sepik Provinces conform closely to those from Madang Province in morphology, but the specific identity of frogs in these regions has not been confirmed.
