Description
Similar in various traits to Pheidole angulifera, Pheidole erratilis, Pheidole schmalzi and Pheidole viriosa. Differing as follows.
Major: yellow; humeri in dorsal-oblique view are a “sharkfin” shape, pointing forward, and from above extend just beyond the margins of the pronotum below; propodeal spines more than half as long as the propodeal basal face preceding them; postpetiole from above diamond-shaped; rugoreticulum fills space between each eye and adjacent antennal fossa, and rest of dorsal head surface mostly carinulate; most of dorsal head surface and all of mesosoma foveolate.
Minor: humeri acute-angular, each bearing a long seta at the tip; occiput narrowed, with a nuchal collar; all of head, mesosoma, and waist foveolate.
MEASUREMENTS (mm) Holotype major: HW 1.12, HL 1.10, SL 0.64, EL 0.14, PW 0.56. Paratype minor: HW 0.56, HL 0.62, SL 0.62, EL 0.08, PW 0.38.
COLOR Major: concolorous medium yellow.
Minor: concolorous pale yellow.
