DIAGNOSIS A medium-large, brown member of the flavens group whose major is distinguished by the unusual bidentate anterior margin of the clypeus; heart-shaped frontal profile of the head; completely carinulate clypeus; shallow antennal fossa; high, subangulate pronotal humerus in dorsal-oblique view; angulate mesonotal convexity and deep, semicircular metanotal groove; and narrow petiolar node in side view.

Similar to Pheidole bidens in possession of a bidentate clypeus and general habitus but differing in presence of an antennal scrobe and many other details of body form, sculpturing, pilosity, and color, as shown and described (q.v.).
