From Wilson (2003): A member of the fallax group, similar in various characters to Pheidole bergi, Pheidole cordiceps, Pheidole eidmanni and Pheidole nitidula, distinguished as follows.

Major: head slightly bicolorous (see Color below); humerus in dorsal-oblique view subangulate; rugoreticulum of head covering a swath between each eye and antennal fossa; carinulae absent from center of vertex, and those to each side reach less than half the distance from eye level to level of occiput; anterior strip of pronotal dorsum carinulate.

Minor: pilosity very long, with some hairs longer than Eye Length; pronotum entirely smooth; occiput narrowed, with convex border, but lacking nuchal collar.

MEASUREMENTS (mm) Lectotype major: HW 1.40, HL 1.40, SL 0.86, EL 0.22, PW 0.70. Paralectotype minor: HW 0.72, HL 0.76, SL 0.82, EL 0.20, PW 0.46.
