DIAGNOSIS Similar in various traits to Pheidole amata, Pheidole ambigua, Pheidole celaena, Pheidole fera, Pheidole germaini, Pheidole peruviana, Pheidole rutilana, Pheidole schwarzmaieri and Pheidole superba, differing as follows.

Major: median carina projects forward slightly as a single, blade like process; occipital cleft deep; carinae originating on frontal lobes fan outward and most reach the occipital border; occipital lobes mostly smooth and sprinkled with scattered foveae; in dorsal-oblique view, humerus raised high as a prominent lobe; propodeal spines thin and vertical on propodeal basal face; postpetiole from above diamond-shaped; promesonotal dorsum entirely carinulate.

Minor: head "tiger-striped" with curving carinulae along the sides and straight carinulae that run from the frontal lobes to the occiput; occiput somewhat narrowed, with nuchal collar; promesonotal dorsum entirely carinulate; propodeal spines short, thin, and vertical on the propodeal dorsal face.

MEASUREMENTS (mm) Holotype major: HW 1.34, HL 1.48, SL 0.70, EL 0.16, PW 0.70. Paratype minor: HW 0.70, HL 0.78, SL 0.66, EL 0.08, PW 0.48.
