Mandible with outer margin shallowly convex; both preapical teeth in the apical third of mandible length. Distal preapical tooth less than half the length of the spiniform proximal; on left mandible may be reduced to a denticle. Scape weakly flattened, broadest at about the midlength; its leading edge moderately convex but not strongly expanded. Cephalic dorsum with a transverse row of 4 short standing hairs close to occipital margin, and with a pair of standing hairs close to highest point of vertex. Pronotal humeral hair flagellate; side of pronotum almost entirely smooth. Disc of postpetiole smooth and shining. Hairs on first gastral tergite short and stiff, very slightly flattened and expanded apically, appearing narrowly elongate-spatulate or extremely feebly remiform.
