DIAGNOSIS Similar to Pheidole bilimeki, Pheidole floridana, Pheidole hazenae, Pheidole rectiluma, Pheidole rectisentis, Pheidole rectispina, Pheidole sospes and Pheidole stomachosa, differing as follows.

Major: propodeal spines robust, half as long as propodeal basal face, vertical to propodeum; frontal lobes, vertex, and dorsal midline strip to occiput carinulate and rugulose; occipital lobes smooth with scattered foveae; sides of head rugoreticulate; humeri longitudinally rugulose, and promesonotal dorsum transversely carinulate; postpetiole from above conulate.

Minor: all of dorsal surface of head from eye level to occiput rugoreticulate, as well as all of promesonotal dorsum; propodeal spines long, robust, and vertical to propodeal basal face.
