From the IUCN Red List Species Account:


Range Description

This species is known from New Ireland Island and from New Britain Island, Papua New Guinea. It might be widespread on New Britain. It occurs up to 1,200 m asl.

Habitat and Ecology

On New Ireland, this species was found in rural gardens and plantations at night and in caves during the day. On New Britain, this species was found in primary rainforest and in disturbed forest adjacent to small rural gardens, and also in streams and wet gulleys. Here, it was found on the forest floor or on logs, 20–50 cm high ( Foufopoulos and Richards 2007). It presumably breeds by direct development.


The population in New Britain appears to be common. It is more common at lower altitudes.

Population Trend


Major Threats

No threats are known to this species, although logging might impact on some populations.

Conservation Actions

The distribution of this species on New Britain needs to be documented, and the impacts of logging need to be assessed. It is not known from any protected areas.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its currently known extent of occurrence is less than 20,000 km², it is common and adaptable with a presumed large population, and it is unlikely to be declining to qualify for listing in a more threatened category.
