This species is known from the eastern tip of the New Guinea mainland, and Woodlark, Rossel, and Tagula (Sudest) islands. It is a lowland species that has been recorded up to 350m asl.
Habitat and Ecology
A fossorial species found in primary or secondary lowland rainforest or cloudforest. Like other species in the genus, it is presumably a direct developer.
It is a reasonably common species where it occurs.
There are no threats to this species at present. The forest on Tagula Island was damaged by logging 100 years ago, but has since recovered. There are no immediate plans for logging and most of the species' known range is forested. The species is utilized on Tagula Island for magic purposes (it is believed to provide fertility to land if planted) but the level of utilization is likely to be too low to be a major threat.
Its distribution, habitat requirements and abundance need to be properly documented, particularly on mainland Papua New Guinea. It is not known to occur in any protected area.
Red List Status
Least Concern (LC)
Although this species is known mainly from isolated records from a large area, it is listed as Least Concern in view of its wide distribution, presumed large population, lack of present threats, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
