Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
A medium-large, yellow member of the flavens group whose major is distinguished by the unusual bidentate anterior margin of the clypeus, heart-shaped head in full-face view, and completely carinulate clypeus.
Similar to Pheidole styrax of Venezuela but different in absence of an antennal scrobe and many other details of body form, sculpturing, pilosity, and color, as illustrated. See also the less similar Pheidole moffetti, Pheidole nasutoides and Pheidole tennantae .
