Apex of scape reached to 19/20 of the distance from antennal socket to occipital corner, antennal club consisted of the apical 5 segments. Eye with one facet. In profile view mesonotum weakly convex, promesonotal suture and metanotal groove distinct. Dorsum of propodeum and declivity subequal and flat, posterodorsal corner blunt. In profile view petiolar node distinctly tapering upward, anterior face straight and vertical, dorsal and posterior faces formed a single arched surface, anterodorsal corner blunt. Subpetiolar process cuneiform, fenestra circular and small, anteroventral corner rounded, posteroventral corner with a large tooth. In dorsal view petiolar node nearly semicircular, anterior and lateral borders formed a single arch, posterior border straight. Gaster weakly constricted between the two basal segments.
