Etymology Referring to the type locality, San Antonio, an "arhuaque" (Arawak) village.

Diagnosis A medium-sized, yellow species with conulate humerus in both major and minor, when seen in dorsal-oblique view. Close to caulicola HNS 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 chalca HNS , chalcoides HNS , mincana HNS , schmalzi HNS , and tragica HNS .

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.

Range Known only from the types of arhuaca HNS sensu str. (Colombia) and of its variety bimons HNS (Ceara, Brazil).

Biology Forel found the type colony under a dried pat of cow dung.
