From Wilson (2003): A member of the flavens group, somewhat similar to Pheidole striaticeps of Mexico and Central America, distinguished as follows.

Major: yellow; Head Width equal to Head Length; occipital cleft deep, with subangulate midline cleft; mesonotal convexity apparent in dorsal-oblique view; postpetiole from above diamond-shaped, with right-angular margins; edges of humeri rugoreticulate; propodeal spines half as long as and perpendicular to basal face of propodeum preceding them; edges of humeri rugoreticulate.

Minor: humeri toothed; propodeal spines more than a third as long as and perpendicular to the basal face of the propodeum facing them; occiput narrowed behind; occiput with prominent midline cleft; head, mesosoma, and waist foveolate and opaque.

MEASUREMENTS (mm) Syntype major: HW 1.00, HL 1.00, SL 0.48, EL 0.12, PW 0.48. Syntype minor: HW 0.50, HL 0.54, SL 0.44, EL 0.08, PW 0.30.
