Distribution based on Regional Taxon Lists
Australasian Region: New Caledonia.

Biology
From present records, this species appears to be restricted to rainforest and cloud forest at higher elevations (500-900m). At Montagne des Sources a worker was collected foraging in open heath or maquis about 20 m from the nearest gully with tall woody shrubs; all other records, including other ground foragers from Montagne des Sources, are from closed forest. Collections come from both sedimentary and ultramafic localities. Nest-site records; under stone (1); in clump of soil and rotting wood (1).
