From Wilson (2003): DIAGNOSIS A somewhat larger brown species, whose major has a bicolorous head, rugoreticulum mesad to the eye, conspicuous foveae scattered over the otherwise smooth posterior half of the dorsal head capsule, and cornulate postpetiole. The mesonotum of the major and minor has no dorsal convexity, and its posterior face descends abruptly to the metanotum.

Somewhat similar to Pheidole arhuaca, Pheidole caulicola, Pheidole chalca, Pheidole chalcoides, Pheidole mixteca and Pheidole scabriventris, but easily distinguished by combinations of many or all of the above traits.
