Antennal sockets not margined with carinae. Interantennal space with a flat triangular elevation that narrows to a short ridge posteriorly approaching the median ocellus. Temple rounded in dorsal view. Third labial palpomere not greatly reduced, more than 1/2 as long as apical palpomere. Notauli depressed and partly or entirely pitted. Scutellar triangle with dense punctures or aciculations. Ventral margin of hind coxal cavities situated below dorsal margin of metasomal foramen. Pegs on anterior surface of fore tibia present. Hind trochantellus lacking longitudinal carinae. Second submarginal cell of fore wing minute, cell about the same diameter as wing veins. First median tergite evenly and completely covered in strong striae, lateral carinae strong but partly obscured by sculpture. Second median tergite wider than long.
