Orthocentrus Gravenhorst, 1829: 1-1097. Type species: Orthocentrus anomalus Gravenhorst, 1829.

Diagnosis.

Clypeus fused with face, forming uniformly convex surface; lower edge of clypeus usually convex or truncate; labrum hidden. Antennal scape unusually long, subcylindrical. Mandibles narrowed apically, not overlapping when closed; lower tooth much shorter than upper tooth, or sometimes completely reduced. Malar space with or without subocular sulcus. Fore wing with pentagonal areolet or without areolet. Hind wing with abscissa of vein Cu present or absent; nervellus reclivous, inclivous or vertical. Ovipositor straight or upcurved, with or without dorsal subapical notch, short, as a rule not longer than apical height of metasoma; ovipositor sheaths with setae along most of the length, except at the very base. Legs generally robust.

Remarks.

Twenty five species of the genus Orthocentrus have been recognized in South Korea, of them fifteen species are new to science. The genus is characterized by significant sexual dimorphism, which often leads to the inability to confidently establish that males and females belong to the same species.
