Pedicel and abdomen short and broad, node of pedicel small and low but distinct, inclined obliquely forwards. Queen with mandibles triangular, with six teeth; clypeus wide, bisinuate along anterior margin; frontal area triangular, depressed, longer than broad, antennal and clypeal hollows confluent; antennal carinae short, wide apart; antennae 12-segmented, somewhat massive. Pedicel with erect node. Wings with one cubital and one discoidal cell. Male with mandibles narrower than in queen, acute; clypeus trapezoidal, convex; eyes very large, ocelli prominent; antennae with 13 segments, the segments much longer proportionately than in queen.
