Although few data are available about this species, it appears to be widespread in the northern lowlands of central New Guinea. It occurs between the Sepik River and the summit of the north coastal ranges, in East Sepik and West Sepik provinces, Papua New Guinea. B. Tjaturadi (pers. comm.) recently found this species in the Cyclops Mountains, Papua, Indonesia, and its distribution might be broader than has so far been documented. It has been recorded from 240-1,000m asl.
Habitat and Ecology
It lives in lowland rainforest, secondary forest and anthropogenic grassland. Like other species in the genus, it presumably breeds by direct development.
It is a fairly common species.
There are no known threats to this species.
Its distribution needs to be properly documented. The range of this species includes the Cyclops Nature Reserve.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its known Extent of Occurrence is less than 20,000km2, it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it can adapt to secondary habitats, it has a presumed large population, and it is unlikely to be in decline.
