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.
Acacia longifolia is a species of Acacia native to southeastern Australia, from the extreme southeast of Queensland, eastern New South Wales, eastern and southern Victoria, southeastern South Australia, and Tasmania. Common names for it include long-leaved wattle, acacia trinervis, aroma doble, golden wattle, coast wattle, sallow wattle and Sydney golden wattle. It is not listed as being a threatened species, and is considered invasive in Portugal, New Zealand and South Africa. In the southern region of Western Australia, it has become naturalised and has been classed as a weed by out-competing indigenous species. It is a tree that grows very quickly reaching 7–10 m in five to six years.
Pleistodontes is a genus of fig wasps native to Australia and New Guinea, with one species from Java. Fig wasps have an obligate mutualism with the fig species they pollinate. Pleistodontes pollinates species in section Malvanthera of the Ficus subgenus Urostigma.
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.
Metapelma is a parasitic wasp genus, the only genus in the family Metapelmatidae. They are parasitoids of longhorn-beetle larvae, which are wood-borers.
Ormocerinae is a subfamily in the chalcidoid wasp family Pteromalidae.
Ceratosolen is an Old World wasp genus in the family Agaonidae. They are pollinators of the monoecious fig subsections Sycomorus and Sycocarpus, and the section Neomorphe, all belonging to the subgenus Sycomorus. The genus is native to the Palearctic, Afrotropical, Indomalayan and Australasian realms.
Apocrypta is an Old World genus of parasitic fig wasps in the family Pteromalidae. They are parasitoids of gall-wasps in the Sycophagini tribe, and especially Ceratosolen species, pollinators of the Sycomorus, Sycocarpus and Neomorphe sections of Ficus. They seem to be fig species-specific.
Trichilogaster signiventris, commonly known as the golden wattle bud-galling wasp, is a species of Australian chalcid wasps that parasitises, among others, Acacia pycnantha. It has been introduced into South Africa, where the golden wattle has become an invasive pest.
Uromycladium is a genus of rust fungi in the family Pileolariaceae. It was circumscribed by mycologist Daniel McAlpine in 1905. The genus was established by McAlpine for rusts on Acacia with teliospores that clustered at the top of a pedicel.
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.
Mikeius hartigi is a species of wasp found in Australia, the type species of its genus. Species of Mikeius are thought to be associated with hosts that induce galls on Acacia and Eucalyptus species.
Austroencyrtus is a genus of parasitic wasps.
Ooencyrtus is a genus of chalcid wasp. William Harris Ashmead named and circumscribed the genus in 1900.
Dirhinus is a genus of parasitic wasps in the family Chalcididae. The genus has a worldwide distribution.
Plutarchia is a genus of chalcid wasp in the subfamily Eurytominae. Alexandre Arsène Girault first circumscribed the genus in 1925; its name honors Plutarch. The genus initially only comprised its type species, P. bicarinativentris, found in Australia. Subsequent species from South Asia and Nigeria have been described and transferred to Plutarchia.
Syrphophagus is a genus of wasps belonging to the family Encyrtidae.
