Minor: dorsal mesosomal surface mostly covered by widely spaced transverse carinulae; propodeal spines vertical to propodeal basal face; postpetiolar node low in side view.

MEASUREMENTS (mm) Holotype major: HW 1.24, HL 1.64, SL 0.64, EL 0.14, PW 0.70. Paratype minor: HW 0.64, HL 0.74, SL 0.62, EL 0.10, PW 0.42.
