Description
DIAGNOSIS Similar to Pheidole bilimeki, Pheidole floridana, Pheidole hazenae, Pheidole rectiluma, Pheidole rectisentis, Pheidole rectispina, Pheidole sospes and Pheidole stomachosa, differing as follows.
Major: propodeal spines robust, half as long as propodeal basal face, vertical to propodeum; frontal lobes, vertex, and dorsal midline strip to occiput carinulate and rugulose; occipital lobes smooth with scattered foveae; sides of head rugoreticulate; humeri longitudinally rugulose, and promesonotal dorsum transversely carinulate; postpetiole from above conulate.
Minor: all of dorsal surface of head from eye level to occiput rugoreticulate, as well as all of promesonotal dorsum; propodeal spines long, robust, and vertical to propodeal basal face.
MEASUREMENTS (mm) Holotype major: HW 0.90, HL 0.98, SL 0.48, EL 0.12, PW 0.48. Paratype minor: HW 0.50, HL 0.54, SL 0.44, EL 0.08, PW 0.32.
COLOR Major: body, scape, and mandibles dark, almost blackish brown; legs and funiculus medium brown.
Minor: head, mesosoma, petiole, and appendages medium brown; postpetiole and gaster dark brown.
Figure. Upper: holotype, major. Lower: paratype, minor. Scale bars = 1 mm.
