Description
DIAGNOSIS Similar to Pheidole pidax of Colombia, distinguished from it and other Pheidole as follows.
Major: yellow; humerus very prominent, in dorsal-oblique view extending from rest of promesonotal profile as a large equilateral triangle; in full-face view occiput much broader than clypeus, and occipital cleft shallow, giving entire head a wedge shape; rugoreticulum extensive from eye to antennal fossa posterior to frontal carina on each side of head; rest of dorsal surface of head carinulate, except for frontal triangle and mid-clypeus; all of mesosoma and waist foveolate; lateral corners of genae in full-face view right-angulate; postpetiole from above oval.
Minor: humeri bluntly spinose, with a long seta emerging form the apex of each; occiput narrow and with a nuchal collar; all of head, mesosoma, and waist foveolate to varying degree; pilosity sparse.
MEASUREMENTS (mm) Holotype major: HW 1.06, HL 1.12, SL 0.60, EL 0.12, PW 0.54. Paratype minor: HW 0.56, HL 0.60, SL 0.64, EL 0.10, PW 0.40.
COLOR Major and minor: concolorous medium yellow.
