From Wilson (2003): A member of the fallax group similar in various characters to Pheidole chiapasana, Pheidole dentata, Pheidole humeridens, Pheidole industa, Pheidole madrensis, Pheidole maja and Pheidole tetroides, and distinguished as follows.

Major: rugoreticulum confined to a small patch just posterior to the circular carinulae of the antennal fossae; carinulae of head reaching slightly posterior to midway between the eyes and occiput; anterior half of pronotal dorsum and all of propodeal dorsum transversely carinulate; pronotal profile in dorsal-oblique view bilobous; postpetiole from above oval, and foveolate.

Minor: all of head, mesosoma, and waist foveolate and opaque; anterior strip of first gastral tergite shagreened; occiput in frontal view concave.

MEASUREMENTS (mm) Syntype major: HW 1.14, HL 1.22, SL 0.82, EL 0.20, PW 0.60. Syntype minor: HW 0.60, HL 0.70, SL 0.78, EL 0.14, PW 0.40.
