Inner margins of mandibles strongly convex in full-face view, at full closure touching at about the midlength and diverging both proximally and distally. Apex of mandible with 2 minute intercalary denticles between apicodorsal and apicoventral teeth. Preapical denticles restricted to distal third or less of mandible, 4 - 5 in n umber and minute; distal most denticle the largest, located very close to the apicodorsal tooth and separated from the remaining 3 - 4 denticles by a short diastema. Scape short and very broad, its anterior margin expanded forward into a large convex lobe; SL only 2.75 X the maximum scape width. Eye small, with only 3 ommatidia in the longest row. Apicoscrobal hair short. Pronotal humeral hair short, very broad, flat and leaf-like.
