Chalcid wasps are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily.
The Mymaridae, commonly known as fairyflies or fairy wasps, are a family of chalcidoid wasps found in temperate and tropical regions throughout the world. The family contains around 100 genera with 1,400 species.
The Eucharitidae are a family of parasitic wasps. Eucharitid wasps are members of the superfamily Chalcidoidea and consist of three subfamilies: Oraseminae, Eucharitinae, and Gollumiellinae. Most of the 55 genera and 417 species of Eucharitidae are members of the subfamilies Oraseminae and Eucharitinae, and are found in tropical regions of the world.
The Eurytomidae are a family within the superfamily Chalcidoidea.
Coccophagus is a large genus of chalcid wasps belonging to the family Aphelinidae.
Anagyrus is a large genus of parasitic wasps from the family Encyrtidae. Anagyrus is distributed throughout the world. A subgenus of Anagyrus is known as Nesoanagyrus
Aphytis is a genus of chalcid wasps in the family Aphelinidae. There are about 130 species.
Megastigmus is a genus of minute wasps. There are more than 134 described species, more than half of which undergo larval development within the seeds of trees and shrubs.
Anicetus is a parasitic wasp genus in the subfamily Encyrtinae.
Telenomus is a genus of parasitoid wasps from 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.

Ooencyrtus is a genus of chalcid wasp. William Harris Ashmead named and circumscribed the genus in 1900.
Psyllaephagus is a genus of chalcid wasps. It was named and circumscribed by William Harris Ashmead in 1900. As of 2017, Psyllaephagus contains approximately 245 species.
Conura is a genus of chalcidid wasps in the family Chalcididae, containing more than 300 species described. They are distributed mostly in the New World, especially in the Neotropical region, where 279 species occur. Conura is divided into three subgenera and 63 species groups, which may not form taxonomic entities but reflect patterns of morphology that are useful for focused studies.
Aphelinoidea is a genus of wasps belonging to the family Trichogrammatidae.
Syrphophagus is a genus of wasps belonging to the family Encyrtidae.
Chalcedectidae is a small family of chalcid wasps, previously classified as part of the subfamily Cleonyminae, in the polyphyletic family Pteromalidae. Most species are parasitoids of wood-boring beetles.
