From Wilson (2003): DIAGNOSIS A member of the “flavens complex” within the larger flavens group, also including Pheidole asperithorax, Pheidole breviscapa (=Pheidole perpusilla), Pheidole cardiella, Pheidole striaticeps, Pheidole exigua, Pheidole flavens, Pheidole goeldii, Pheidole mittermeieri, Pheidole moerens, Pheidole nitidicollis, Pheidole pholeops, Pheidole sculptior and Pheidole trinitatis, differing in the following combination of traits.

Major: shallow antennal scrobes present, their surfaces smooth and shiny; parallel longitudinal carinulae cover all of the head surface (including the occiput) except for the center of the clypeus and frontal triangle; anterior and lateral margins of the pronotal dorsum carinulate; mesosoma and sides of waist foveolate and opaque; the strongly convex promesonotum descends to the metanotal groove through a distinct 45-degree posterior face; propodeal spines well-developed.

Minor: carinulae limited to anterior half of head capsule, including lateral margins of the frontal lobes; all of the head and mesosoma, and sides of the waist, foveolate and opaque; the remainder of the body smooth and shiny; propodeal spines well-developed.

MEASUREMENTS (mm) Lectotype major: HW 0.78, HL 0.76, SL 0.64, EL 0.10, PW 0.40. Paralectotype minor: HW 0.44, HL 0.50, SL 0.42, EL 0.08, PW 0.30.

COLOR Major and minor: body concolorous light reddish yellow (“orange”); appendages clear medium yellow.
