Description
A medium-sized, bicolorous member of the flavens group whose major is distinguished by the prominent “sharkfin” shape of the pronotal humerus in dorsal-oblique view. In this respect it resembles the major of Pheidole schmalzi of South America but is distinct in the way the angles extend past the lower humeral margins in dorsal view, and in the wider, nearly perfectly semicircular shape of the occipital border. The minor has a much less prominent humeral profile in dorsal-oblique view than that of schmalzi, and the carinulae on the dorsal surface of the head do not extend beyond the eye.
Compare also with Pheidole arhuaca, Pheidole boliviana, Pheidole caulicola, Pheidole chalca, Pheidole nitidicollis, Pheidole crinita, Pheidole flavifrons, Pheidole mincana, Pheidole sagana, Pheidole tambopatae and Pheidole tysoni.
MEASUREMENTS (mm) Holotype major: HW 0.88, HL 0.92, SL 0.42, EL 0.10, PW 0.46. Paratype minor: HW 0.48, HL 0.54, SL 0.40, EL 0.06, PW 0.34.
COLOR Major: yellowish brown; head faintly bicolorous, with head capsule anterior to eye a slightly contrasting dark yellow.
Minor: head light brown; gena a slightly contrasting dark yellow; anterior half of mesosoma dark yellow and posterior half yellowish brown.
