Camponotus setosus

This apparently uncommon species is restricted to the Kimberley region of Western Australia. All known collections consist of ground-foraging workers in open Eucalyptus woodlands.

Identification
Erect hairs present on tibiae. Metanotal groove a distinct, shallow trough. These two characters will separate this distinctive species from others in this group.

Distribution based on Regional Taxon Lists
Australasian Region: Australia.
