Description
DIAGNOSIS From Wilson (2003): A large reddish brown species, similar to Pheidole antillana of the Lesser Antilles and Pheidole avia, Pheidole bucculenta, Pheidole hetschkoi, Pheidole heyeri, Pheidole hortonae, Pheidole mamore, Pheidole praeses, Pheidole rhytifera and Pheidole sarcina of South America.

Major: propodeal spines long, stout, and nearly erect; postpetiole cornulate; sculpturing of dorsal surface of head consists entirely of longitudinal carinulae, which are confined to the anterior two-thirds of the head capsule except for two carinulae that proceed to the occiput along the midline; promesonotal dorsum almost completely covered by transverse carinulae. The major is very similar to that of Pheidole bucculenta, but the minor is easily distinguished, as illustrated.

Minor: occiput, sides of head mesad to the eyes, and lateral margins of the pronotal dorsum rugoreticulate; remainder of dorsal surface of head weakly carinulate; propodeal spines long, thin, and erect.

MEASUREMENTS (mm) Lectotype major: HW 2.10, HL 2.12, SL 0.98, EL 0.20, PW 1.02. Paralectotype minor: HW 0.82, HL 0.84, SL 0.94, EL 0.14, PW 0.54.

COLOR Major: concolorous light reddish brown.
