This species has been recorded only from Yapen Island, Cenderawasih Bay in Papua Province, in the Indonesian part of New Guinea. The only records are from near the road to Ambaiduru Village, about 17 km in a direct line northeast of Serui, at 1,000 to 1,100m a.s.l. on Amoman Mountain (1°45´S and 136°19´E). It almost certainly occurs more widely on Yapen Island, and could well occur on the New Guinea mainland (R. Günther, pers. comm.).
Habitat and Ecology
All records have been from near a road traversing a partly logged mossy rainforest. Their calling sites are in small holes 5-20 cm below he surface, beneath trees or shrubs. Most animals occurred in loose groups. It is unlikely to be able to survive in completely opened-up habitats (R. Günther, pers. comm.).
It is common in its only know location (R. Günther, pers. comm.).
It is probably affected by selective logging and clear felling of its habitat (R. Günther, pers. comm.).
Its only known site is not in a protected area. 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.
