Thynnoidea is a superfamily of hymenopterans in the order Hymenoptera. There are 2 families and hundreds of described species in Thynnoidea. [1]
These two families belong to the superfamily Thynnoidea:
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism —that is, they have a wormlike larval stage and an inactive pupal stage before they mature.
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.
Sawflies are wasp-like insects that are in the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies.
Vespoidea is a superfamily of wasps in the order Hymenoptera. Vespoidea includes wasps with a large variety of lifestyles including eusocial, social, and solitary habits, predators, scavengers, parasitoids, and some herbivores.
The Hymenopteran superfamily of parasitoid wasps, Platygastroidea, has often been treated as a lineage within the superfamily Proctotrupoidea, but most classifications since 1977 have recognized it as an independent group within the Proctotrupomorpha. It is presently has some 4000 described species. They are exclusively parasitic in nature.
Anaxyelidae is a family of incense cedar wood wasps in the order Hymenoptera. It contains only one living genus, Syntexis, which has only a single species, native to Western North America. Fossils of the family extend back to the Middle Jurassic, belonging to over a dozen extinct genera, with a particularly high diversity during the Early Cretaceous. Syntexis lay eggs in the sapwood of conifers, preferring recently burnt wood.
The Pamphilioidea are a small superfamily within the Symphyta, containing some 250 living species restricted to the temperate regions of Eurasia and North America. These hymenopterans share the distinctive feature of a very large, almost prognathous head, which is widest ventrally.
The Tenthredinoidea are the dominant superfamily of sawflies within the Symphyta, containing some 8,400 species worldwide, primarily in the family Tenthredinidae. All known larvae are phytophagous, and a number are considered pests.
Cimbicidae is a family of sawflies in the order Hymenoptera. There are more than 20 genera and 200 described species in Cimbicidae. Larvae are solitary herbivores.
Trigonalidae is a family of parasitic wasps in the suborder Apocrita. They are the only living members of the superfamily Trigonaloidea. Trigonalidae are divided into 2 subfamilies; Orthogonalinae and Trigonalinae. These wasps are extremely rare, but surprisingly diverse, with over 90 species in 16 genera, and are known from all parts of the world. It is possibly the sister group to all Aculeata.
Cephidae is a family of stem sawflies in the order Hymenoptera. There are about 27 genera and more than 160 described species in Cephidae.
The Thynnidae are a family of large, solitary wasps whose larvae are almost universally parasitoids of various beetle larvae, especially those in the superfamily Scarabaeoidea. Until recently, the constituents of this family were classified in the family Tiphiidae, but multiple studies have independently confirmed that thynnids are a separate lineage.
Telenominae is a subfamily of parasitoid wasps in the family Scelionidae. It was previously considered a subfamily of Platygastridae.
Heloridae is a family of wasps in the order Hymenoptera known primarily from fossils, and only one extant genus, Helorus, with 12 species found worldwide. Members of Helorus are parasitic on green lacewings.
Teleasinae is a subfamily of parasitoid wasps in the family Scelionidae. It was previously considered a subfamily of Platygastridae.
Pompiloidea is a superfamily that includes spider wasps and velvet ants, among others, in the order Hymenoptera. There are 4 families in Pompiloidea.
Tiphioidea is a suggested superfamily of stinging wasps in the order Hymenoptera. There are three families in Tiphioidea, Bradynobaenidae, Tiphiidae, and Sierolomorphidae.
Oraseminae is a subfamily of chalcid wasps in the family Eucharitidae. There are at least 10 genera in Oraseminae.
Karatavitidae is an extinct family of sawflies, known from the Jurassic period, they are the only members of the superfamily Karatavitoidea. While once proposed to be grouped with the Orussoidea in the infraorder Orussomorpha, they are now considered to be the closest relatives of clade containing Orussoidea and Apocrita. There are about 7 genera in Karatavitidae.
Megastigmidae is a family of chalcid wasps in the order Hymenoptera. There are about 12 genera and more than 170 described species in Megastigmidae. Megastigmidae was formerly considered a subfamily of the family Torymidae.
