From the IUCN Red List Species Account:


Range Description

This species is known only from Milne Bay Province in Papua New Guinea, specifically from two of the D'Entrecasteaux Islands (Goodenough Island and Fergusson Island). On Goodenough Island it is known from 1,600m asl, and from Fergusson Island it is known from 1,720-1,830m asl in the east of the island.

Habitat and Ecology

It is found on the forest floor and in trees in montane tropical rainforest, where it presumably breeds by direct development. It is not known whether or not it can tolerate secondary habitats, since it occurs above the altitude at which rural gardening takes place.


Little information is available regarding the population status of this species, but it might be moderately common within its tight altitudinal band. It has only recently been rediscovered after an absence of records for many years.

Population Trend


Major Threats

There are no known threats to this species at the higher altitudes where it occurs. The habitat on Goodenough Island is heavily impacted by gardening and fires, as well by as expanding human populations, up to 300m asl, but is still intact at higher altitudes. On Fergusson Island, the habitat is impacted by gardening up to 300-400m asl in the east, and up to 700m asl in the west.

Conservation Actions

The distribution of the species needs to be determined and the current population status needs to be assessed. It is not known from any protected areas.

Red List Status

Data Deficient (DD)


Listed as Data Deficient in view of continuing uncertainties as to its extent of occurrence, status and ecological requirements.
