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.
