Platygastroidea
The Hymenopteran superfamily of parasitoid wasps, Platygastroidea, has often been treated as a lineage within the superfamily Proctotrupoidea, but most classifications since 1977 have recognized it as an independent group. It is presently composed of one extinct and three extant families, with some 4000 described species. They are exclusively parasitic in nature.
The family Scelionidae was briefly considered to be a subfamily of the Platygastridae, though subsequent analyses suggest that Scelionidae can be retained as a monophyletic lineage if a few genera are removed.
