Odynerus chinensis de Saussure, 1863, designated by Bohart, 1939.

Diagnosis.

Body generally small and slender (Figs 1, 7, 14-15, 23, 30, 37, 63, 73); anterior surface of pronotum usually with a pair of median foveae, which sometimes contiguously forms U-shaped (Fig. 69), V-shaped (Figs 3, 18, 40, 48, 52, 57, 60, 65, 75) or a transverse fovea; tegula campanulate, broadest in the middle, length somewhat more than width; parategula just reaching apex of tegula; tergum I generally without a basal transverse carina (Figs 5, 10, 26, 33, 50, 59, 71, 78), but in some Nearctic species present; tergum II without an acarinarium; the terminal segment of male antenna bent backward like a hook, apex usually reaching the base or middle of the segment XI (Fig. 19). This genus is similar in some characters to Parancistrocerus Bequaert, which can be distinguished by the presence of an acarinarium on the metasomal tergum II in Parancistrocerus .

Distribution.

Nearctic, Neotropic, Palearctic and Oriental regions.
