This species is known only from the southern slopes of the Nakanai Mountains on the island of New Britain, in the Bismarck Archipelago, Papua New Guinea, at 517-850m asl, in the vicinity of the western end of Jacquinot Bay. It is likely to occur more widely, at least in the Nakanai Mountains, and perhaps elsewhere on New Britain.
Habitat and Ecology
Most specimens have been encountered in primary and old secondary rainforest either in ravine bottoms or on hill slopes in leaf litter. It can probably tolerate some habitat alterations, but is unlikely to survive in completely open habitats. This species presumably breeds by direct development.
It is probably not common, but it is a very difficult species to detect.
The most obvious threats are forest logging and, if the species occurs more widely on New Britain, permanent conversion of habitat to oil palm plantations (the currently known locality is probably not at risk from this latter threat).
It is not known from any protected areas. 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.
