This species has been recorded from three areas in Papua Province, in the Indonesian part of New Guinea: 1) at 500 to 1,150m a.s.l. in the Waira and Amoman Mountains northeast of Serui, on Yapen Island, Cenderawasih Bay (1°47’S and 136°20’E); 2) on the New Guinea mainland along the Nabire-Mapia road at 750m a.s.l. (3°30’S, 135°44’E); and 3) in the Foya Mountains (02°36’S, 139°05’E) in northern New Guinea. It is likely to occur more widely, especially between known locations.
Habitat and Ecology
This species lives on the ground in primary and secondary rainforests, where they perch on bare humus soil and on, or in, leaf litter. It probably cannot survive in completely open-up habitats (R. Günther, pers. comm.). The species presumably breeds by direct development, depositing its eggs in damp terrestrial habitats, without dependence on aquatic ecosystems.
It is rather rare in its only known localities (R. Günther, pers. comm.).
The species might be at risk in at least some of its sites from selecting logging and clear-felling (R. Günther, pers. comm.). However, it seems to be a widespread species, so it is probably not seriously threatened.
Its only known sites are not in protected areas. Surveys are needed to determine the status, distribution and ecological requirements of the species, and to determine whether or not there are any threats. If its range proves to be genuinely small, a protected area should be established.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its probable wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
