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 nitidicollis, 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.
Figure. Upper: syntype, major. Lower: syntype, minor. Scale bars = 1 mm.
Type Material
COLOMBIA: San Antonio, Sierra Nevada de Santa Marta, col. Auguste Forel. Musee d'Histoire Naturelle Genève and Museum of Comparative Zoology - as reported in Wilson (2003)
Etymology
Referring to the type locality, San Antonio, an “arhuaque” (Arawak) village. (Wilson 2003)
