Proctotrupoidea is a hymenopteran superfamily containing seven extant families,[1] though others have been recognized in the past, most of these having been removed to a recently erected superfamily Diaprioidea. Of the remaining families, only Proctotrupidae contains a substantial number of species, with over 400 described.[2] The others are small, often relictual groups. See links for individual families for details of life history and diversity.
