is a morphologically and genetically compact species. The major and media workers are easily identified by the large and often tusk-like basal tooth that is variably situated along the basal margin. In many WA populations this tooth is highly-developed and, at the rear of the gape, virtually occludes the gap between the mandible and the anterior margin of the clypeus. In eastern populations the tooth is situated more anteriorly along the apical margin of the mandible and is less strongly developed. Minor workers lack this anatomical feature but can be distinguished from similar species by a combination of their glabrous mesosoma, the straight anterior margin of the clypeus, the appearance of the head capsule and the elongate eye. The five-gene tree suggests that this species falls within the

is found in all mainland states except the ACT and Vic. The species is also absent from Tasmania. Existing label data for dry, pinned material is scanty, but a specimen from SA was taken in cane grass. Sequenced material has been collected from red clay soil, mulga woodland and from suburban lawns. This species is particularly common in and around the Perth metropolitan area, and can occur in highly built up locations. The phylogenetic position the species occupies and the nature of the mandible suggests it is largely or wholly granivorous.
