A member of the fallax group, closest to Pheidole cardinalis, Pheidole caribbaea, Pheidole kukrana, Pheidole mantilla and Pheidole obscurior (=Pheidole susannae) (also scan Pheidole alienata, Pheidole fallax, Pheidole jelskii, Pheidole lanigera, Pheidole lattkei, Pheidole lovejoyi, Pheidole nubicola, Pheidole puttemansi, Pheidole roushae, Pheidole susannae and Pheidole tobini), and distinguished by the following combination of traits.

Major: tip of antennal scape approaches occipital corner to within scape maximum width; posterior dorsal profile of head very weakly concave; bicolorous, with reddish yellow head and brown body; propodeal spine long and thin; postpetiole diamondshaped; pronotum bare of carinulae.

Minor: propodeal spine moderately long and very thin (needle-like); mesonotal convexity angulate; nuchal collar present.

MEASUREMENTS (mm) Holotype major: HW 1.22, HL 1.36, SL 1.12, EL 0.20, PW 0.60. Paratype minor: HW 0.60, HL 0.82, SL 1.20, EL 0.16, PW 0.42.
