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 Platygastridae is a large group of exclusively parasitoid wasps, mostly very small (1–2 mm), black, and shining, with geniculate (elbowed) antennae that have an eight-segmented flagellum. The wings sometimes lack venation, though they may have slight fringes of setae.

Sceliphrinae is a subfamily of thread-waisted wasps in the family Sphecidae. There are about 6 genera and at least 140 described species in Sceliphrinae.
Sphex nudus, the katydid wasp, is a species of thread-waisted wasp in the family Sphecidae.
Scelioninae is a subfamily of wasps in the family Platygastridae. It is a very large cosmopolitan group of exclusively parasitoid wasps, mostly small (0.5–10 mm), often black, often highly sculptured, usually with geniculate (elbowed) antennae that have a 9- or 10-segmented flagellum. It was formerly considered to be a family Scelionidae but has been reclassified as a subfamily of the Platygastridae.
