Description

From Wilson (2003): A medium-sized, yellow species with conulate humerus in both major and minor, when seen in dorsal-oblique view. Close to Pheidole caulicola of Costa Rica but with less prominent humeri, longer antennal scapes, and broader, more angulate postpetiolar node in both castes, as well as completely foveolate central pronotal dorsum in the major.

Also similar but less so to Pheidole chalca, Pheidole chalcoides, Pheidole mincana, Pheidole schmalzi and Pheidole tragica.

MEASUREMENTS (mm) Syntype major (Mus. Comp. Zool. Harvard): HW 0.80, HL 0.86, SL 0.40, EL 0.10, PW 0.44. Syntype minor (Mus. Comp. Zool. Harvard): HW 0.46, HL 0.50, SL 0.44, EL 0.06, PW 0.30.

COLOR Major and minor: concolorous yellow.
