Eye moderate (eye length 0.20-0.49 length of side of head capsule); in full-face view, eyes set at about midpoint of head capsule; in profile, eye set around midline of head capsule; roughly ovoid, eye narrowed posteriad. In full-face view, frontal carinae distinctly concave; frontal lobes curved inward in front of antennal insertion. Anteromedial clypeal margin straight and

Minor workers of this tiny species are recognizable because of their roundly conical propodeum when seen in profile, and their large propodeal spiracle. Like other members of their clade, they have a scalloped mesopleuron. No sequencing work has been done on the taxon. The major worker is unknown and the minor

||

|
||
material is confined to two pins of ants collected in the Gawler Ranges, SA. There are no accompanying collection data (apart from the fact that the worker on one pin would have been pitfall-trapped by Greenslade) and nothing more is known of this ant.
