From Wilson (2003): Similar to Pheidole coffeicola, Pheidole laevifrons, Pheidole pubiventris and Pheidole variegata (= Pheidole pubiventris), but especially to Pheidole laevinota, a partially sympatric species from which it differs as follows.

Major: patch of rugoreticulum located near middle of outer margin of antennal fossa; at most, sparse carinulae occur along anterior margin of pronotum; entire dorsal surface of promesonotum foveolate and opaque; upper half of propodeal side foveolate but not carinulate; postpetiole trapezoidal from above, with angulate sides; humerus in dorsal-oblique view rounded.

Minor: humerus in dorsal-oblique view rounded; entire promesonotum foveolate.

MEASUREMENTS (mm) Lectotype major: HW 1.12, HL 1.14, SL 0.80, EL 0.22, PW 0.58. Paralectotype minor: HW 0.64, HL 0.70, SL 0.70, EL 0.18, PW 0.40.

COLOR Major: not recorded.

Minor: body concolorous brown, appendages a slightly contrasting yellowish brown; hair pale yellow.
