This species is known only from two localities in the Adelbert Mountains, at around 1,500m asl, in Madang Province, Papua New Guinea.
Habitat and Ecology
It lives on the ground in primary tropical rainforest, where it breeds by direct development. It can also survive in secondary and degraded habitats and appears to be quite adaptable.
It appears to be common at the type locality.
There is little information on threats to this species. The region where it occurs is densely populated by people, and forest clearance for rural gardens is taking place, but this species is not thought to be threatened, given its adaptability.
The Nature Conservancy is currently negotiating a land concession in the Adelbert Mountains, which would help to conserve this species.
