Antennae with 12 segments. Anterior clypeal margin with a very feeble median indentation. Mandibles unsculptured except for hair-pits. Frontal carinae strong, running almost to occipital corners before becoming confused with the occipital rugoreticulum and surmounted throughout their length by a narrow raised rim or flange. Maximum diameter of eye 0.18, about 0.28 x HW. Propodeal spines elongate but broad in profile, elevated. Metapleural lobes narrowly elongate-triangular. Petiole node in profile shaped as in insolens (Fig. 45, this paper), in dorsal view as broad as long. Dorsum of head with irregular, spaced-out longitudinal rugulae and with a weak occipital rugoreticulum. Dorsal alitrunk reticulaterugose but without a transverse carina at the pro- and mesonotal junction. Petiole dorsum weakly rugulose, the postpetiole dorsally with a few very faint longitudinal markings and a little very feeble punctulation. Gaster unsculptured. All dorsal surfaces of head and body with stout, stiff, erect or suberect hairs. Colour pale yellow.
