General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Riverland and elsewhere
The worker caste is ~13mm long.
The shape of the top of their heads is diagnostic, almost with ears pointing up, as is the petiole. The bottom of the front "shoulders" have small spurs. Under the head is concave, terminating in sharp edges to the rear of the "cheeks". They have a very scaloped exoskeleton.
They have thick spines on the front legs, which are well hidden.
These are quite abundant on Ellura, and in other semi-arid evironments. We have photographed 16 specimens in Jan, Feb, Apr, May, June, Aug, Sept, Oct, Nov & Dec. Apparantly they have long term permenant nests, so will focus on on a local nest during the remaining 2 moths (Mar & Jul) expecting that they don't close their nest at all.
