Description
From Wilson (2003): Major: frontal lobes greatly expanded anteriorly, so that their edges project beyond the lateral head margins in full-face view, and their flat anterior margins just reach the anterior clypeal border; in side view the frontal lobes project downward over the clypeus like thin horns; pronotum greatly enlarged, in dorsal-oblique view 4X higher than the mesonotal convexity, and seen fromabove more than 2X as wide as the mesonotum; head bicolored (see color below).

Minor: nearly identical to minor of Pheidole cavifrons (q.v.) except for large eye, as illustrated.

COLOR Major: body medium yellow except for anterior dorsal surface of head, which is medium brown.

Minor: concolorous yellow.
