Belongs within: Evanioidea.Contains: Gasteruption. The Aulaciformes are a clade of parasitoid or larval predatory wasps characterised by the absence of the jugal lobe in the hind wing, fusion of the first and second metasomal terga, sexually dimorphic antennal segmentation, and elongate propleuron, and rigid attachment of the pronotum and mesepisternum (Grimaldi & Engel 2005). Members… Continue reading Aulaciformes


Belongs within: Hymenoptera.Contains: Siricoidea, Apocrita. The Unicalcarida are a major clade of wasps characterised by the reduction of the posterior protibial spur. Members include the subclades Cephoidea, Xiphydriidae and Siricoidea with phytophagous larvae. Xiphydriidae have a long ‘neck’ with cervical sclerites that are longer than high (Naumann 1991). Parasitic larvae evolved in the ancestors of… Continue reading Unicalcarida


Belongs within: Proctotrupomorpha.Contains: Baeini, Telenominae, Platygastrinae. The Platygastroidea are a clade of small wasps that begin life as parasitoids of insect and spider eggs though some may not emerge from the host until it has reached a more advanced stage of development. They are characterised by a unique telescoping ovipositor mechanism, and the presence of… Continue reading Platygastroidea


Belongs within: Cynipoidea.Contains: Aulax, Dryophanta, Aulacidea, Synergus, Diastrophini, Cynipini. The Cynipidae are a family of small phytophagous wasps either forming galls in angiosperms or developing as inquilines of other gall-formers (Grimaldi & Engel 2005). They are characterised by a medially constricted metascutellum, an open marginal cell on the fore wing, and the absence of a lateral… Continue reading Cynipidae


Belongs within: Proctotrupomorpha.Contains: Diplolepidini, Cynipidae, Figitidae. The Cynipoidea are a clade of small wasps that appear to have been ancestrally parasitic on plant-boring insects (Grimaldi & Engel 2005). Members have closely placed antennae and a more or less flat lateral panel on the pronotum. Classification of the superfamily is uncertain with recognised families often being… Continue reading Cynipoidea


Belongs within: Eulophidae.Contains: Apleurotropis, Pseudomphale, Chrysonotomyia, Omphale, Closterocerus, Pediobius, Pleurotroppopsis, Entedon. The Entedoninae are a group of eulophid wasps characterised by the presence of only a single pair of bristles on the scutellum, and a generally tapering submarginal vein on the forewing with a reduced number of bristles that does not usually smoothly connect to… Continue reading Entedoninae


Belongs within: Proctotrupoidea. The Proctotrupidae are a group of small wasps that are mostly endoparasites of Coleoptera larvae, rarely of Diptera. They are commonly found in low vegetation in damp forest habitats. The species Exallonyx trifoveatus is found worldwide as a parasite of Staphylinidae in compost heaps (Naumann 1991). Most proctotrupids have the wing venation… Continue reading Proctotrupidae


Belongs within: Aphelinidae.Contains: Aphelinus. The Aphelininae are small chalcidoid wasps with a linea calva and six or less antennal segments. Genera include Marlattiella with just three antennal segments in males and four in females (Hayat 1983). Aphelininae [Aphytini]HB13 | i. s.: Pteroptrixella Girault 1932G32 | `–*P. metallica Girault 1932H83 | MashimaroHB13 | Arrhenophagus chionaspidisWB37 |–Marietta… Continue reading Aphelininae


Belongs within: Chalcidoidea.Contains: Cratocentrinae, Haltichellinae, Conura, Dirhininae, Phasgonophorini, Epitranus, Brachymeria (Brachymeria). The Chalcididae are a group of chalcidoid wasps characterised by large, ventrally dentate hind femora that are adapted for jumping. They typically develop as parasitoids in insect pupae (Bouček 1988). Characters (from Bouček 1988): Body often large and non-metallic, gaster convex, not collapsing; gena… Continue reading Chalcididae


Belongs within: Chalcidoidea.Contains: Aphycus, Microteryina, Encyrtus, Miraini, Ectromatini. The Encyrtidae are a family of small wasps whose larvae are mostly endoparasites of Hemiptera or insect larvae. The species Anagyrus pseudococci has been widely reared commercially for use in mealybug control. Encyrtids have historically been divided between two subfamilies, Tetracneminae and Encyrtinae. Females of Tetracneminae possess a… Continue reading Encyrtidae
