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 within the Proctotrupomorpha. It is presently has some 4000 described species. They are exclusively parasitic in nature.
The hymenopteran family Scelionidae is a very large cosmopolitan group of exclusively parasitoid wasps, mostly small (0.5–10 mm), often black, often highly sculptured, with (typically) elbowed antennae that have a 9- or 10-segmented flagellum. It was once considered to be a subfamily of the Platygastridae, but has been revived in the most recent classification of Platygastroidea.
The Mymarommatoidea are a very small superfamily of microscopic fairyfly-like parasitic wasps. It contains only a single living family, Mymarommatidae, and three other extinct families known from Cretaceous aged amber. Less than half of all described species are living taxa, but they are known from all parts of the world. Undoubtedly, many more await discovery, as they are easily overlooked and difficult to study due to their extremely small size.
The Stephanidae, sometimes called crown wasps, are a family of parasitoid wasps. They are the only living members of the superfamily Stephanoidea. Stephanidae has at least 345 living species in 11 genera. The family is considered cosmopolitan in distribution, with the highest species concentrations in subtropical and moderate climate zones. Stephanidae also contain four extinct genera described from both compression fossils and inclusions in amber.
The Aulacidae are a small, cosmopolitan family of wasps, with two extant genera containing some 200 known species. They are primarily endoparasitoids of wood wasps (Xiphydriidae) and xylophagous beetles. They are closely related to the family Gasteruptiidae, sharing the feature of having the first and second metasomal tergites fused, and having the head on a long pronotal "neck", though they are not nearly as slender and elongate as gasteruptiids, nor are their hind legs club-like, and they have more sculptured thoraces. They share the evanioid trait of having the metasoma attached very high above the hind coxae on the propodeum.
Anteris is a genus of wasps in the family Platygastridae. There are about 15 described species in Anteris.
Maimetshidae is an extinct family of wasps, known from the Cretaceous period. While originally considered relatives of Megalyridae, they are now considered to probably be close relatives of Trigonalidae.
Serphitidae is a family of microscopic parasitic wasps known from the Cretaceous period.
New Jersey Amber, sometimes called Raritan amber, is amber found in the Raritan and Magothy Formations of the Central Atlantic (Eastern) coast of the United States. It is dated to the Late Cretaceous, Turonian age, based on pollen analysis of the host formations. It has been known since the 19th century, with several of the old clay-pit sites now producing many specimens for study. It has yielded a number of organism fossils, including fungi, plants, tardigrades, insects and feathers. The first identified Cretaceous age ant was described from a fossil found in New Jersey in 1966.
Telenominae is a subfamily of parasitoid wasps in the family Scelionidae. It was previously considered a subfamily of Platygastridae.
Embolemidae is a family of small solitary parasitoid wasps with around 70 species in 2 genera distributed around the world. The few species whose biology is known are parasites on planthopper nymphs of the families Achilidae and Cixiidae. There is debate regarding the status of the genus named Ampulicomorpha by Ashmead in 1893, generally considered now to be a junior synonym of Embolemus (e.g.,), though some authorities dispute this (e.g.,)
Teleasinae is a subfamily of parasitoid wasps in the family Scelionidae. It was previously considered a subfamily of Platygastridae.
Macroteleia is a genus of parasitoid wasps in the family Platygastridae. There are more than 140 described species in Macroteleia.
Baeomorpha is an extinct genus of rotoitid parasitic wasp, known from the Late Cretaceous of Laurasia. The type species, B. dubitata was named by Charles Thomas Brues for a specimen found in 72 million year old Canadian Amber. The vast majority of species are known from the Russian Taimyr amber, of upper Santonian age but two species are known from the upper Campanian Canadian amber, while one species is known from the lower Cenomanian Burmese amber.

Embolemus is a genus of wasps belonging to the family Embolemidae. There is debate regarding the status of the genus named Ampulicomorpha by Ashmead in 1893, generally considered now to be a junior synonym of Embolemus (e.g.,), as a few authorities dispute this (e.g.,).
Neuroscelionidae is a family of wasps in the superfamily Platygastroidea. It contains only one extant genus, Neuroscelio, with two other genera known from fossils. Members of Neuroscelio are known from Southeast Asia and Australia. Their hosts are unknown.
Janzenella is a genus of wasp, the only member of the family Janzenellidae within the superfamily Platygastroidea. It contains only a single living species, Janzenella innupta, which has only been collected in Costa Rica. Fossil members of the living species have also been described from Miocene aged Dominican amber. A Late Eocene fossil species, Janzenella theia is known from specimens entombed in Baltic amber.
Geoscelionidae is a family of wasps in the superfamily Platygastroidea. It contains three extant species in two genera, native to South America and Africa, and several other genera known from fossils. It was originally erected as the tribe Geoscelionini within Scelionidae. It was raised to a full family in 2021.
Sparasionidae is a family of wasps in the superfamily Platygastroidea. Known species are parasitoids of the eggs of orthopterans.
