Description
DIAGNOSIS Similar to Pheidole bilimeki, Pheidole floridana, Pheidole hazenae, Pheidole rectiluma, Pheidole rectispina, Pheidole rectitrudis, Pheidole sospes and Pheidole stomachosa, differing as follows.
Major: mostly blackish brown, with bicolored head; from margins of dorsal head surface to space between eyes and antennal fossae rugoreticulate, as well as lateral margins of frontal lobes; all of central third of head, including much of the vertex and occiput, solely foveolate; all of head and mesosoma overall foveolate; in dorsal-oblique view humerus subangulate; propodeal spines robust and nearly vertical to propodeal basal face in side view; postpetiole from above conulate.
Minor: eyes set well forward on head; propodeal spines robust, nearly vertical to propodeal basal face; almost all of head and all of mesosoma foveolate and opaque.
MEASUREMENTS (mm) Holotype major: HW 0.90, HL 0.98, SL 0.50, EL 0.12, PW 0.48. Paratype minor: HW 0.50, HL 0.58, SL 0.46, EL 0.06, PW 0.34.
COLOR Major: head bicolored, with surface anterior to eye level medium reddish brown and rest blackish brown; also sides of pronotum and petiole medium reddish brown; and rest of body blackish brown; appendages light reddish brown.
Minor: body blackish brown, appendages brownish yellow.
