This species is known only from the type locality, at an altitude of 2,200m asl, on the summit of Mount Binnie, in the Star Mountains, Western Province, Papua New Guinea.
Habitat and Ecology
This species lives in burrows and under large stones in disturbed and primary montane rainforest, and breeds by direct development.
When collected it was observed to be relatively uncommon, but there have been no further surveys of the area since then.
It is known only from an area that has been severely impacted by the Ok Tedi mine, and so it is probably experiencing habitat loss.
The impacts on this species of forest damage and habitat damage at the summit of Mount Binnie, especially that resulting from the Ok Tedi mine, should be closely monitored.
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been described, and there is still very little information on its Extent of Occurrence, population status and ecological requirements.
