Description
DIAGNOSIS Similar in various traits to Pheidole chalca of Mexico, Pheidole mera of Texas, and Pheidole neolongiceps of Cuba, differing as follows.
Major: yellow; shallow antennal scrobe present; carinulae originating on frontal lobes travel posteriorly all the way to but not across the occiput, which is smooth and sprinkled with foveae; space between eye and antennal fossa on each side of head rugoreticulate; almost all of mesosoma smooth and shiny; center of promesonotal dorsum in side view flat; postpetiole from above elliptical, with angulate lateral margins.
Minor: eye large, Eye Length almost a fourth of Head Width, and nearly as long as distance from eye to anterior clypeal margin; occiput very broad, its margin weakly concave; propodeal spines small, in side view equilaterally triangular.
MEASUREMENTS (mm) Holotype major: HW 0.80, HL 0.94, SL 0.42, EL 0.14, PW 0.50. Paratype minor: HW 0.44, HL 0.46, SL 0.38, EL 0.08, PW 0.26.
COLOR Major: concolorous medium yellow, with mandibles a slightly darker shade.
Minor: concolorous medium yellow.
