Description
DIAGNOSIS Similar in various traits to Pheidole horribilis, Pheidole minax, Pheidole ursus and Pheidole macromischoides, differing as follows.
Major: propodeal spine stout, about half as long as propodeal basal face; rear third of head smooth, with scattered foveae; a loose rugoreticulum between eye and antennal fossa on each side; frontal lobes and vertex carinulate; anterior half of promesonotum rugoreticulate, rear half smooth; postpetiolar dorsum foveolate and carinulate; gaster entirely smooth.
Minor: occiput and sides of head to level of eyes rugoreticulate; lower half of mesopleuron loosely rugose, and dorsum foveolate only, with rest of promesothorax rugoreticulate.
MEASUREMENTS (mm) Holotype major: HW 1.80, HL 1.86, SL 0.94, EL 0.20, PW 0.90. Paratype minor: HW 0.76, HL 0.70, SL 0.82, EL 0.14, PW 0.50.
COLOR Major: body, antennae, mandibles medium reddish brown; legs brownish yellow.
Minor: mesosoma, waist, and appendages light to medium reddish brown; head and gaster dark reddish brown.
