As Ophirion and Lixophaga include parasitoids of Neotropical Vespidae , the following characters can be used to identify males and females of both genera:

1. Eyes bare or with short hairs ( Fig. 2E ); ocellar setae absent; frontal setae above pedicel reclinate and continuous to reclinate orbital setae ( Fig. 1B ); 2 katepisternal setae; wing with strong costal spine ( Fig. 2C ); abdomen without discal setae on intermediate abdominal tergites ..................................... Ophirion

- Eyes bare; ocellar setae present; frontal setae inclinate ( Fig. 4E ); 2–3 katepisternal setae; wing with weak costal spine ( Fig. 4C ); abdomen with or without discal setae on intermediate abdominal tergites ......................................................................... Lixophaga
