From the IUCN Red List Species Account:


Range Description

This recently described species is known from the slopes and valleys east of the main ridge of the Wondiwoi Mountains at the base of the Wandammen Peninsula, Papua, Indonesia, from 450-800m asl. It is possible that it is also present on Yapen Island and in the Fakfak Mountains, although further studies are needed to confirm the identity of animals from these regions.

Habitat and Ecology

It is found in tropical forest, where specimens were mainly found perched on the leaves of shrubs between 0.3 and 3m above the ground. Like other species in the genus, this is presumably a species that breeds by direct development.


This species is relatively abundant.

Population Trend


Major Threats

The threats to this species are not known.

Conservation Actions

It might be present in Wondiwoi Nature Reserve.

Red List Status

Data Deficient (DD)
