From the IUCN Red List Species Account:


Range Description

This species occurs in a relatively wide area of mountains in western Papua New Guinea, extending almost to the Papuan (Indonesia) border. It almost certainly also occurs in suitable habitats in Papua, Indonesia but as yet has not been recorded from there. It occurs from 600-1,600 m asl.

Habitat and Ecology

It occurs along small streams in rainforest. Like other species in the genus, it is presumably a species that breeds by direct development.


It seems to be abundant where it occurs, and presumably has large populations throughout its known range and elsewhere in suitable, unexplored areas. It is probably stable and secure.

Population Trend


Major Threats

There are no known threats.

Conservation Actions

None required at present. It is not known from any protected areas.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its known extent of occurrence is probably not much greater than 20,000 kmĀ², it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it has a presumed large population, and it is unlikely to be in decline.

Taxonomic Notes

When the first assessment for this species was published (in 2004) it was under the generic name Austrochaperina. Peloso et al. (2016) transferred the species to the genus Copiula. This is not a reassessment of the status of this species; instead it is an updated version of the original assessment to reflect this taxonomic change.
