From the IUCN Red List Species Account:


Range Description

This species is probably endemic to Sudest (Tagula) Island in the Louisiade Archipelago, off the southeastern tip of Papua New Guinea. There are records from Vanua Mountain and the western slopes of Mount Rio at 127-410m asl, and it probably occurs through most or all of Sudest Island (Kraus, 2007; Hiaso and Richards, 2006). Local people have also reported it from the vicinity of Araeda, on the north coast of the island. This species was not found on surveys of the nearby Rossel and Misima islands, the other large islands of the Louisiade Archipelago.

Habitat and Ecology

This arboreal species is associated with primary lowland rainforest (Kraus, 2007; Hiaso and Richards, 2006). Most specimens were found around the margins of a muddy, largely dried, oxbow pond along a slow-flowing river (Kraus, 2007). Adults and tadpoles were also located around or in water-filled pig wallows on ridges up to 410m asl, far from any natural standing water (Kraus, 2007). Local people haves reported that the species also inhabits sago swamps and other areas with standing water (Kraus, 2007). It can probably tolerate some habitat disturbance, but not complete opening up of its habitat. The eggs are attached to leaves and suspended over water (Kraus, 2007).


It is probably a moderately common species.

Population Trend


Major Threats

The habitat of the species is not seriously threatened at the present time, but there is no direct information on threats to this species.

Conservation Actions

It is not known from any protected areas. Surveys are needed to determine its geographic distribution (in particular whether or not it is known from any other islands, such as Misima and Rossel), ecological requirements, threats and conservation needs.

Taxonomic Notes

F. Kraus (pers. comm.) and S. Richards (pers. comm.) consider that Litoria rostandi Kraus, 2007 is a synonym of L. hilli.
