This species is currently only known from Misima Island in the Louisiade Archipelago, Papua New Guinea (Richards and Oliver, 2007). It has been found in three locations at 200-300m asl: the Misma mine site (152° 47.761' E, 10° 39.540' S); the North Dump Rainforest (152° 47.876' E, 10° 39.848' S); and, Boma Village (152° 47.064' E, 10° 39.090' S) (Richards and Oliver, 2007). It can be expected to occur more widely on the island.
Habitat and Ecology
Most specimens have been found in leaf litter on the rainforest floor. One specimen was collected from moist, dense rainforest regrowth of an old garden adjacent to rain forest. It presumably breeds by direct development without dependence on water.
There is little information on its abundance, but it appears to be moderately common in rainforest (Richards and Oliver, 2007).
The rainforest on Misima has been fragmented by intensive human activities, including mining and small-scale agriculture (S. Richards, pers. comm.), though the species appears to survive at least in old regrowth.
It is not known from any protected areas. Surveys are needed to determine its geographic distribution, ecological requirements, threats and conservation needs.
