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 Eurytomidae are a family within the superfamily Chalcidoidea.
Chrysonotomyia is a genus of small parasitoid wasps in the family Eulophidae, with over 170 described species. Members of the genus tend to attack insect larvae that feed within living plant tissue, such as gall-formers, leaf-miners and stem-miners. The Neotropics contain most described species. Within the region, most attack galls induced by Cecidomyiidae midges, although there are also records from Torymidae galls, Cynipidae galls, Psyllidae galls, Momphidae leaf mines and scale insects in the family Coccidae.
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.
Cleonymus is a genus of wasps in the family Cleonymidae. There are more than 40 described species in the genus, which has been recorded on every continent except Antarctica.
Entedoninae is a subfamily of wasps in the family Eulophidae. The subfamily includes over 90 genera.
Eulophinae is a subfamily of wasps in the family Eulophidae which includes over 90 genera.
Psyllaephagus is a genus of chalcid wasps. It was named and circumscribed by William Harris Ashmead in 1900. As of 2019, Psyllaephagus contains approximately 245 species. They are found worldwide: Australia has 100 described species; the Palaearctic region has about 57 species, India has about 20, and Africa about 30.
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.
Chalcedectus is a genus of chalcid wasps, previously classified as part of the subfamily Cleonyminae, in the polyphyletic family Pteromalidae. It is the only genus in the monotypic family Chalcedectidae. Most species are parasitoids of wood-boring beetles.
Aenacius is a genus of parasitic wasps in the family Encyrtidae. They are parasitoids of mealybug nymphs.
