Crematogaster dispar

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).
