From the IUCN Red List Species Account:


Range Description

This species is known only from around the Yuwong Village at around 400m asl in the Tree Kangaroo Conservation Project area on Huon Peninsula, in Morobe Province in Papua New Guinea (Richards and Oliver, 2006). It probably occurs more widely.

Habitat and Ecology

Most specimens have been encountered in primary rainforest calling from high in the canopy on ridges adjacent to the Tarona River (Richards and Oliver, 2006). One specimen was in a tree adjacent to a forest garden and two specimens were collected from primary rainforest in trees overhanging puddles that had formed in a previously dry rocky creek bed after torrential rain (Richards and Oliver, 2006). One male descended to within three metres of the pools during observation, suggesting that this species may descend after torrential rain to breed in pools on the forest floor (Richards and Oliver, 2006).


There is no information on its abundance, as it is a canopy species which is hard to find.

Population Trend


Major Threats

The habitat where the species is known to occur is reasonably well conserved. However, the species probably occurs more widely, and might be found in less well protected sites. It is probably dependent on intact rainforest.

Conservation Actions

This only known site is within the Tree Kangaroo Conservation Project area (Richards and Oliver, 2006), where the habitat is conserved. Surveys are needed to determine its geographic distribution, ecological requirements, and conservation needs.

Red List Status

Data Deficient (DD)

Taxonomic Notes

Richards and Oliver (2006) separated this species from Litoria graminea.
