Major: frontal lobes project for short distance as lobes, in side view; humerus obliquely subangulate and mesonotal convexity rightangulate in dorsal-oblique view; petiolar node tapers to a rounded point in side view; postpetiole spinose; shallow, narrow antennal scrobe present; carinulae originating on frontal lobes spread outward all the way to the occiput; occipital lobes smooth with scattered foveae; small rugoreticulum behind each antennal fossa; most of pronotal dorsum and propodeal dorsum carinulate.

Minor: occiput narrow, with nuchal collar; all of posterior dorsum of head and almost all of mesonotal and propodeal dorsa “tigerstriped” with semicircular and transverse carinulae; propodeal spine reduced to denticle.
