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 .
MEASUREMENTS (mm) Holotype major: HW 1.04, HL 1.06, SL 0.56, EL 0.14, PW 0.44. Paratype minor: HW 0.54, HL 0.58, SL 0.46, EL 0.06, PW 0.34.
COLOR Major: body and mandibles medium reddish yellow, appendages dark yellow.
Minor: body medium reddish yellow, appendages plain medium yellow.
