This is a very widespread species that is common in rainforest habitats on mainland New Guinea from the western tip of the Vogelkop Peninsula in Papua, Indonesia, to eastern Papua New Guinea. It occurs at altitudes up to 1,500m asl, although there are old records from 2,600m asl.
Habitat and Ecology
It is a terrestrial and scansorial species that calls from bushes and saplings in rainforest understorey at night, and hides beneath litter and logs during the day. It has also been found in disturbed habitats such as gardens and degraded forest. It breeds by direct development, and the male parents carry the babies on their backs (Günther et al., 2001; Günther, 2006).
It is a common species with overall numbers likely to be in the millions.
There are no known threats to this species.
Its range overlaps several protected areas. The extent of occurrence of the species needs to be further documented.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This form might be a complex of more than one species.
