Distribution
Buenos Aires and Santa Fé, Argentina (Kempf 1972b).

This taxon was described from Argentina.

Description
From Wilson (2003): The most distinctive member of the aberrans group and one of the most unusual Pheidole species.

Major: frontal lobes drawn out into sharp, downward- and inward-curving horn-like extensions that reach beyond the clypeus to overhang the bases of the mandibles; laterally the edges of the frontal lobes extend past the margins of the head; bicolorous (see color below); carinulae of head confined to a broad band from the level of the frontal triangle to the transverse carina that delimits the beginning of the occiput.

Minor: promesonotal dorsum covered by semicircular carinae; carinulae on head mostly limited to antennal fossae and clypeus.

MEASUREMENTS (mm) Lectotype major: HW 1.08, HL 1.24, SL 0.42, EL 0.10, PW 0.66. Paralectotype minor: HW 0.48, HL 0.56, SL 0.42, EL 0.08, PW 0.34.

COLOR Major: concolorous reddish yellow, including midclypeus, but “horns” (extended frontal lobes), together with the frontal triangle and vertex, are dark brown, forming a “mask” over anterior dorsal surface of the head.
