Identification
Shattuck (2009) - Carinae on pronotum and anterior mesonotum “V”-shaped; sides of head behind compound eyes smooth; antennal scapes with low longitudinal ridges; body smaller (HW < 0.70). This species can be separated from all other known Australian species by the combination of “V”-shaped sculpturing on the dorsum of the mesosoma and the small body size.
