Differs from other members of group ( capillata  HNS  , jeannei  HNS  , q.v.) in the major in the following combination of traits: no rugoreticulum on head, humerus subangulate in dorsal-oblique view; no trace of a propodeal spine, with the basal and declivitous faces of the propodeum in side view meeting in a very wide oblique angle.
