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 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 (over 3000 described species in some 176 genera) 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. thumb They are generally idiobionts, attacking the eggs of various insects, such as butterflies (e.g., the hackberry emperor), and spiders. Many scelionids are imp

Nixonia is a genus of wasps. It is the only member of the family Nixoniidae in the superfamily Platygastroidea. They are amongst the largest of the platygastroids at up to 9 mm in length. Members of the genus are known from Africa, the Indian subcontinent and Southeast Asia. The biology of only one species is known, which parasitizes orthopteran eggs.

Telenomus is a genus of parasitoid wasps belonging to the subfamily Telenominae. The genus was first described by Alexander Henry Haliday in 1833. Species in this genus parasitise the eggs or immature stages of other insects.

Caradiophyodus is an extinct genus of minute wasps in the superfamily Platygastroidea within the order Hymenoptera. The genus was described in 2023 by George Poinar Jr. and Fernando E. Vega and placed in the monotypic family Caradiophyodidae and is represented by a single species, Caradiophyodus saradae. The fossil was found in mid-Cretaceous Burmese amber from northern Myanmar and represents one of the earliest known records of platygastroid wasps.

Sparasionidae is a family of wasps in the superfamily Platygastroidea. Known species are parasitoids of the eggs of orthopterans.
