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.
Alexandre Arsène Girault was an American entomologist specializing in the study of chalcid wasps. An eccentric and controversial figure, Girault was also a prolific and dedicated entomologist. He published more than 325 papers and described over 3000 new taxa from Australia.
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.
Ablerus is the only genus in the family Azotidae. The genus was created by the American entomologist Leland Ossian Howard in 1894 for the species named in that year by William Harris Ashmead as Centrodora clisiocampae. The genus Azotus was synonymized with Ablerus by Alexandre Arsène Girault in 1913 and Hyatt synonymized Myocnemella with Ablerus in 1994, leaving Ablerus as the sole genus within the subfamily Azotinae. Azotinae was elevated in rank in 2013 to become the monotypic family Azotidae.
Trichilogaster is a small genus of chalcid wasps in the family Melanosomellidae, previously they were included in family Pteromalidae subfamily Ormocerinae. With one described exception, they all are Australian species that are gall-formers on Australian species of Acacia. The exception is an Arabian species. Apart from its ecological interest, the genus is of practical importance because some of its members are successful biocontrol agents in South Africa at least, where T. acaciaelongifoliae and T. signiventris have been established successfully to control invasive Australian Acacia species, notably Acacia longifolia and Acacia pycnantha.
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.
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.
