From the IUCN Red List Species Account:


Range Description

This species is known only from 2,050-2,600m asl on Mount Dayman and Mount Simpson, in Milne Bay Province, Papua New Guinea. It might be endemic to this mountain complex.

Habitat and Ecology

This fossorial frog is usually found in either montane closed-canopy forest or (more frequently) in open tussock grass and shrublands. It presumably breeds by direct development.


It is a common species in appropriate habitat.

Population Trend


Major Threats

There are unlikely to be any threats to it as its habitat is sufficiently isolated from areas of human settlement such that habitat disturbance is insignificant.

Conservation Actions

The extent of occurrence of the species needs to be documented and the population status needs to be assessed. It is not known from any protected areas.

Red List Status

Data Deficient (DD)


Listed as Data Deficient because it is still known only from two localities, and there is insufficient information on its extent of occurrence, status and ecological requirements.
