In profile, the pronotum and mesonotum form a strong convexity, and this is very distinctive of the ant. The major worker also has a uniformly microreticulate head.

Erect bristly setae all over the head, body, antennal scapes and legs and a thoracic hump in the minor worker are sufficient to identify this species. The major worker has a distinctive, uniformly microreticulate frons.
