The morphometric profile of this species is unique. Minor worker: the combination of uniformly foveolate face and mesosoma, lack of promesonotal groove, very long posteriorly-directed propodeal spines, long scapes, and orange color is distinctive. Major worker: the combination of strongly cordate head, long scapes, uniformly foveolate sculpture over most of face, long propodeal spines, and orange color is distinctive. (Longino 2009)
