Description
DIAGNOSIS Similar in different traits to Pheidole mixteca, Pheidole scabriventris and Pheidole tragica, also from Mexico, differing as follows.
Major: a broad rugoreticulum occurs between eye, antennal fossa, and frontal carina on each side of the head; midclypeus partially carinulate, and carinulae travel from the frontal lobes across the vertex but fall short of the occiput; all of head and mesosoma foveolate and opaque; anterior half of central strip of first gastral tergite shagreened; occipital cleft broad and deep; propodeal spines robust and backward-directed; postpetiole from above diamond-shaped.
Minor: eye set well forward on head; propodeal spines half as long as the propodeal basal face and backward-directed; pilosity sparse; occiput broad, its margin concave, and lacking nuchal collar. All of head and mesosoma foveolate and opaque.
MEASUREMENTS (mm) Holotype major: HW 0.92, HL 1.00, SL 0.50, EL 0.14, PW 0.46. Paratype minor: HW 0.50, HL 0.52, SL 0.42, EL 0.06, PW 0.32.
COLOR Major: body and mandibles medium reddish brown, other appendages dark yellow.
Minor: concolorous light reddish yellow.
