diagnosis A medium-sized, yellowish brown (major) to brownish yellow (minor) species similar to arhuacaHNS and caulicolaHNS, but differing in the major by the more rounded, lower humerus seen in dorsal-oblique view, more distinct mesonotal convexity, and completely smooth promesonotal dorsum; in the minor by the smaller propodeal spine and presence of carinulae mesad to the eye; and in both castes by their darker color.

Paralectotype minor: HW 0.50, HL 0.54, SL 0.44, EL 0.08, PW 0.32. color Major: concolorous brownish yellow. Minor: concolorous light, yellowish brown.
Range Veracruz, Mexico (type locality) and, according to J. T. Longino, widespread in the Atlantic and Pacific lowlands of Costa Rica.
Biology Longino (1997): "This species occurs in mature wet forest. It is a relatively common arboreal ant, nesting in dead branches and under epiphytes. Colonies often appear large, with workers scattered over a wide area." Males are present in Wheeler's type series, collected on 16 May in an epiphyte (Tillandsiarum streptophylla).
