From the IUCN Red List Species Account:


Range Description

This species is known only from New Britain Island, in the Bismarck Archipelago, Papua New Guinea. It has so far been confirmed only at two localities (Brown et al., 2006): near Sulu and Silali Villages in the foothills of the Nakanai Mountains, West New Britain (Foufopoulos & Brown 2004); and Wanui, East New Britain (near Sampun Village (05° 21.638'S, 152° 05.266'E)). It has been found at 300–500m a.s.l. It is likely to occur more widely.

Habitat and Ecology

Both known sites are in primary rainforest. These frogs call from elevated perches (leaves and branches) as high as 2m above the ground. They presumably breed by direct development without dependence upon aquatic habitats. There is no information on whether or not it can adapt to heavily degraded habitats, but some closely related species are very adaptable (S. Richards, pers. comm.).


There is little information on its abundance, as it had previously been confused with Platymantis schmidti. However, at Wanui it was 8-10 times more abundant that P. schmidti, which appears to be more common at lower elevations.

Population Trend


Major Threats

No information is available on threats to this species. If it is dependent upon undisturbed forest, it could be impacted by ongoing forest clearance on New Britain.

Conservation Actions

It has not been recorded from any protected areas, though a protected area is planned for the Wanui site. Surveys are needed to determine its distribution, ecological requirements and conservation needs.

Red List Status

Data Deficient (DD)


Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.
