This rare Far North Queensland rainforest species is known from a single collection consisting of two specimens, one a worker and the other an ergatoid (with an enlarged mesosoma).
Shattuck (2009) - Sculpturing “V”-shaped on pronotum grading into “U”-shaped on mesonotum; body larger (HW > 0.8mm). This species can be separated from all other known Australian species by the combination of “V”-shaped sculpturing on the mesonotum and the large body size.
