Material not physically examined. Unknown.
Literature. Viehmeyer (1916), Overbeck (1924) [as Dorylus (Dichthadia) levigatus var. breviceps].
Localities. (Only localities where workers were found are given here, as male occurrences are not accurate inferences of nest locations) Central Catchment Nature Reserve; Lower Peirce Reservoir; Rifle Range Road.
Habitat/Ecology. Primary and/or mature secondary forest — colonies were found in soil.
Remarks. Considered a kind of Old World ‘army ant’ — a general term for ants characterized by cooperative group foraging/predatory tactics and nomadic behaviour. Solitary male alates have been reported from urban residential or commercial areas away from forested areas — these are isolated incidences of males dispersed far from their original nest sources.
