Diagnosis. According to van der Vecht (1963), this genus is characterized by the following characteristics: labrum of female with very short hairs, at most with a few longer hairs at its anterior margin. Apical margin of clypeus wide, more or less emarginated. Concavity of propodeum margined by a crest, which is incised dorsally in the middle, and is separated from metanotum by short horizontal area (propodeal shelf). T1 with transverse ridge separating anterior vertical face from posterior horizontal one. Parastigma short, distinctly less than half as long as the stigma. Cubital cell 3 separated from apex of radial cell by long distance, much more than half width of latter cell.
