This hypogaeic ant is very common on the mainland in the vicinity of Margaret River, Pemberton and Augusta, where it forms populous colonies under stones deeply imbedded in the soil (Wheeler 1934). Colonies are often found in cryptic situations such as inside rotting logs or within moss (Heterick 2009).
Heterick (2009) - A small, yellowish-and-brown species in which the promesonotum is often smooth and shining.
Wheeler (1934) - The brown females measure 7-8 mm. and are very large compared with the yellow workers, which are only 2-2.5 mm. in length. The female larvae are nearly spherical.
