Types . 4 worker syntypes (3 (1 missing gaster) in MCZC; 1 in MVMA) from Burracoppin, Western Australia . Diagnosis . Pronotum rounded, lacking spines, propodeum with elongate spines directed upward at angle of greater than 60° to horizontal plane (may be almost vertical), the angle between them approximately 45°.
