Gaster. Gaster shining with superficial microreticulation; pilosity of first gastral tergite consisting of well-spaced, erect and semi-erect setae interspersed with regularly placed appressed setae.

On Lake Austin, the ant builds a cup-shaped mound of soil around the nest hole which is five or more centimetres above the dry lake surface, possibly as insurance against waterlogging. Some nests seen were more than forty metres from the edge of the Lake. This species also occurs in SA, and may be the
