A small yellow member of the flavens group, similar to Pheidole infernalis, Pheidole peltastes, Pheidole sospes and Pheidole termitobia, distinguished by the following combination of traits.

Major: Antennal scrobe present, its surface weakly foveolate; occiput rugoreticulate, with remainder of dorsal head surface longitudinally carinulate; carinulae near the cephalic midline curving inward; promesonotal dorsal profile forms a single high, semicircular curve.

Minor: Almost identical to that of Pheidole sospes (see illustration of that species).

MEASUREMENTS (mm) Holotype major: HW 0.74, HL 0.80, SL 0.36, EL 0.06, PW 0.34. Paratype minor: HW 0.38, HL 0.40, SL 0.34, EL 0.06, PW 0.24.
