From the IUCN Red List Species Account:


Range Description

As currently understood taxonomically, this species occurs throughout New Guinea (both Indonesia and Papua New Guinea, and including Yapen, Biak, Goodenough, Fergusson and Misima islands) from close to sea level up to at least 1,920m asl.

Habitat and Ecology

It burrows in the forest floor in lowland and hill rainforest, and also in degraded forest, forest edges, rural gardens, and around landslides. It breeds by direct development.


It is widespread but occurs at relatively low densities.

Population Trend


Major Threats

None are known, given its adaptability and wide distribution.

Conservation Actions

Taxonomic studies are needed to determine whether or not more than one species is included in this "taxon". It occurs in many protected areas.

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Taxonomic Notes

This form is a complex of more than one species, and more than one species is currently included in Callulops robustus (S. Richards pers. comm.).
