Holotype. TL 3.0, HL 0.80, HW 0.57, CI 71, ML 0.37, MI 46, SL 0.42, SI 74, PW 0.34, AL 0.87. Mandible with a small preapical tooth. Apicoscrobal hair present; without laterally projecting hairs on upper scrobe margin anterior to this. Cephalic dorsum with a pair of erect fine hairs that straddle the midline close to the occipital margin; usually also with a shorter erect hair on lateral margin of occipital lobe but without erect hairs at highest point of vertex. Dorsum of head densely reticulate-rugulose, tops of rugulae and spaces between rugular meshes finely punctulate. Promesonotal dorsum rugulose, predominantly longitudinally so; similar sculpture present on propodeal dorsum but much weaker, finer and less conspicuous. Side of pronotum longitudinally rugulose; katepisternum smooth; metapleuron with some punctate sculpture anteriorly but most of its surface, and that of side of propodeum, longitudinally rugulose. Anterior coxae with weak transverse rugulae. Pronotal humeral hair long and fine, flagellate or looped apically (apparently fragile, broken off at about its midlength in half the paratypes). Pronotal dorsum with 1-2 pairs of erect fine hairs, mesonotum with 3-4 similar pairs. First gastral tergite with long fine filiform to flagellate hairs. Dorsal surface of hind femur without standing hairs, but 1-2 may be present on ventral surface; dorsal (outer) surfaces of hind tibia and basitarsus each with 1-2 long erect freely projecting filiform or flagellate hairs. Propodeal teeth short, triangular and acute. Petiole in profile claviform.

Paratypes. TL 3.0-3.2, HL 0.80-0.86, HW 0.57-0.60, CI 69-73, ML 0.37-0.40, MI 45-49, SL 0.42-0.44, SI 73-76, PW 0.30-0.35, AL 0.87-0.90 (5 measured).
