Description
DIAGNOSIS Similar in various traits to Pheidole bilimeki, Pheidole floridana, Pheidole hazenae, Pheidole rectiluma, Pheidole rectisentis, Pheidole rectitrudis, Pheidole sospes and Pheidole stomachosa, differing as follows.
Major: propodeal spine half as long as propodeal basal face and perpendicular to it; humeri low and subangulate; mesonotal convexity present; postpetiole from above elliptical, with angulate lateral margins; all of dorsal surface of head except occipital lobes, frontal triangle, and midclypeus carinulate; all of mesosoma and most of head and waist foveolate and opaque; anterior fringe of first gastral tergite shagreened.
Minor: propodeal spine half as long as the propodeal face and vertical on it; postpetiolar node somewhat depressed; occiput broad, its margin concave; all of head and mesosoma foveolate and opaque, no rugoreticulum and almost no carinulae.
MEASUREMENTS (mm) Holotype major: HW 1.00, HL 1.14, SL 0.56, EL 0.14, PW 0.50. Paratype minor: HW 0.44, HL 0.50, SL 0.46, EL 0.08, PW 0.30.
COLOR Major: dark, even blackish brown.
Minor: body medium brown, appendages yellowish brown.
