Characters of mandibularis-complex. Proximal preapical tooth located just distal of midlength on inner border of mandible. Outer margins of mandibles only shallowly curved at full closure. Leading edge of scape with 1-2 hairs in the basal third that are distinctly curved toward the base of the scape. Propodeal declivity with upper and lower teeth linked by a lamella, the teeth variable in shape and size but lower tooth somewhat longer than the upper. Disc of postpetiole broader than long, with very variably developed costulate sculpture. At minimum costulae extremely short and weak, restricted to anterior margin of disc; at maximum costulae strong and traversing entire length of disc; many intermediate stages known. First gastral tergite with fine hairs on basal quarter to third; at minimum a single transverse row close to base but usually with others also present. Basigastral costulae distinct, longer than thickness of postpetiolar posterior spongiform collar.
