Description
A member of the crassicornis group, most resembling Pheidole guerrerana, and differing from that and other species of the group by the following combination of traits.
Major: rugoreticulum on head extends mesad to eye anteriorly half way to the anterior genal border and posteriorly nearly halfway to the occipital borders; a loosed, ladder-like rugoreticulum also extends along the midline of the dorsal surface of the head capsule from the occiput halfway to the frontal triangle; pilosity very long and dense; postpetiole from above oval, not laterally angulate.
Minor: humerus in dorsal-oblique view subangulate; propodeal spines reduced to denticles; petiolar node from side tapers to a point;occiput broad, and nuchal collar absent.
MEASUREMENTS (mm) Holotype major: HW 1.26, HL 1.38, SL 0.82, EL 0.18, PW 0.64. Paratype minor: HW 0.60, HL 0.75, SL 0.80, EL 0.14, PW 0.40.
COLOR Major: concolorous reddish yellow.
Minor: head and gaster plain light brown; mesosoma, waist, and appendages yellowish brown.
