The family Eunotidae is monophyletic group of predators of eggs and crawlers of Coccoidea (Hemiptera: Sternorrhyncha). Eunotids have a maximum of ten antennal flagellomeres, ventrally divergent eyes, and an acropleuron that is not expanded. The chapter provides a diagnosis, discusses relevant morphology, and summarizes their distribution, natural h...

The logical basis of identification keys and the principles underlying character selection are briefly discussed. The key is dichotomous in form and is intended to identify all known Chalcidoidea species to family, or in some cases to a lower level incertae sedis taxon. A set of shortcuts is provided to direct users to major branch points in the ke...

Ormyridae are robust chalcids, with metacoxae enlarged (usually about two times longer than procoxal length) and broadly connected to mesosoma, almost always with occipital carina and often also with a very convex mesosoma and strongly sclerotized metasoma (dorsally sculptured in the case of most of Ormyrinae). Members are either gall-formers or pa...

Diparidae were previously treated as a subfamily of Pteromalidae. As most species are leaf-litter inhabitants, they display a marked sexual dimorphism: females are usually apterous or brachypterous, often with a highly modified mesosoma as a potential result of adaptation to this environment, while males are usually fully winged. Eleven genera and...

The revised concept of Pteromalidae treats it as a monophyletic group containing eight subfamilies of quite different habitus (Colotrechninae, Erixestinae, Metasteninae, Miscogastrinae, Ormocerinae, Pteromalinae, Sycophaginae, Trigonoderinae), including one of the most common model organisms, Nasonia vitripennis. Pteromalidae is a highly diverse an...

Background Mesopolobus Westwood, 1833 consists of about 135 valid species worldwide. After the fundamental monograph of Graham (1969), 12 species have been described from continental Europe and three species have been described from the Canary Islands and Malta. Amongst them, one species, Mesopolobus blascoi Askew, 1994, has been synonymised under...

The circumscription of the family Ormyridae (Hymenoptera: Chalcidoidea) is revised after phylogenetic analysis based on ultra‐conserved elements (UCEs) and comparative morphological assessment of the chalcid ‘Gall Clade’. Six genera are treated in the family, including two new genera, Halleriaphagus van Noort and Burks, gen. nov ., and Ouma Mitroiu...

As a preliminary step towards the development of a key to genera of several families of Afrotropical Chalcidoidea, seven new genera in four families are described: Cerocephalidae–Milokoa Mitroiu, gen. nov. (type species: Milokoa villemantae Mitroiu, sp. nov.); Epichrysomallidae–Delvareus Rasplus, Mitroiu & van Noort, gen. nov. (type species: Delvar...

Chalcidoidea are mostly parasitoid wasps that include as many as 500 000 estimated species. Capturing phylogenetic signal from such a massive radiation can be daunting. Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution. We combined 1007 exons obtained with Anchored Hybrid Enrichme...

The introduction of the biological control agent Torymus sinensis Kamijo (Hymenoptera, Chalcidoidea, Torymidae) to control the populations of the chestnut gall wasp Dryocosmus kuriphilus Yasumatsu (Hymenoptera, Cynipidae) is considered one of the successful programs in biological control. The species was involved in interspecific hybridisation in J...

The family Pteromalidae (Hymenoptera: Chalcidoidea) is reviewed with the goal of providing nomenclatural changes and morphological diagnoses in preparation for a new molecular phylogeny and a book on world fauna that will contain keys to identification. Most subfamilies and some tribes of Pteromalidae are elevated to family level or transferred els...

Capturing phylogenetic signal from a massive radiation can be daunting. The superfamily Chalcidoidea is an excellent example of a hyperdiverse group that has remained recalcitrant to phylogenetic resolution. Chalcidoidea are mostly parasitoid wasps that until now included 27 families, 87 subfamilies and as many as 500,000 estimated species. We comb...

The previously endemic Australian genus Habritella Girault & Dodd, 1915 is reported for the first time in the Afrotropical region with four new species: H. africana sp. nov., H. mandibulata sp. nov., H. noyesi sp. nov., and H. viridifrons sp. nov.
