General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Riverland and elsewhere
1st Live Photo on-line:
The shape of the back, face and the petiole are diagnostic. This is a minor worker and is about 9mm long. There are no pictures of this species anywhere on the net, so it's taken years to finally find out what it is; using this excellent, ameteur friendly key from the SA museum
We just found a major worker for the first time and are pleased to be able to show a comparision shot, as well as diagnostics for the major worker cast of this species
It was ~13mm long. The minor worker is surprisingly hairy in comparision.
