Etymology Named after the myrmecologist and collector of the type series James Trager.
diagnosis A member of a complex of PheidoleHNS species with giant majors having short bristly hair, in the fallaxHNS group and comprising asturHNS, oxyopsHNS, praeustaHNS, and trageriHNS. P. trageriHNS is distinguished among them by the following combination of traits. Major: lacking rugoreticulum on head; one carinula on each side of the dorsal cephalic midline reaches the occiput but otherwise nearly the entire posterior half of the dorsal surface of the head capsule is smooth and shiny; pronotum faintly bilobous in dorsaloblique view; propodeal spines stout, long, and vertical to the basal propodeal face; postpetiolar node seen from above trapezoidal; pronotum entirely smooth and shiny.
Minor: occiput narrowed somewhat, with nuchal collar; propodeal spine reduced to a denticle; entire mesosoma, including pronotum, foveolate and opaque.
Measurements (mm) Holotype major: HW 2.10, HL 2.44, SL 1.04, EL 0.26, PW 0.92. Paratype minor: HW 0.62, HL 0.80, SL 0.94, EL 0.16, PW 0.44.
