Argentina: widespread in the country, including Buenos Aires, Chabut, Córdoba, Mendoza, and Salta (Kempf 1972b).

This taxon was described from Argentina.

Description
From Wilson (2003): A medium-sized, yellow member of the fallax group, distinguished as follows:

Major: head heart-shaped; propodeal spines reduced to denticles; postpetiolar node seen from above roughly trapezoidal; mesonotal convexity prominent, and in dorsal-oblique view seeming to “lean” posteriorly; carinulae on frontal lobes restricted to lateral halves, and rest of cephalic sculpturing confined to the level of the eyes and capsule anterior to them.

Minor: occiput very broad, lacking nuchal collar; humerus angulate; sculpturing on head limited to anterior fourth of dorsal surface.

Most similar to and possibly synonymous with Pheidole dione.

MEASUREMENTS (mm) Lectotype major: HW 1.44, HL 1.46, SL not measured, EL 0.22, PW 0.72. Paralectotype minor: HW 0.70, HL 0.74, SL 0.86, EL 0.16, PW 0.42.

COLOR Major: medium yellow, gaster a slightly contrasting yellowish brown.

Minor: head and mesosoma reddish yellow, waist and gaster medium brown.
