Thynnoidea is a superfamily of hymenopterans in the order Hymenoptera. There are at least 2 families and about 10 described species in Thynnoidea.
These two families belong to the superfamily Thynnoidea:
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 superfamily Apoidea is a major group within the Hymenoptera, which includes two traditionally recognized lineages, the "sphecoid" wasps, and the bees. Molecular phylogeny demonstrates that the bees arose from within the Crabronidae, so that grouping is paraphyletic, and has led to a reclassification to produce monophyletic families.
Sawflies are the insects of 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, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. The suborder Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera.
The Apocrita are a suborder of insects in the order Hymenoptera. It includes wasps, bees, and ants, and consists of many families. It contains the most advanced hymenopterans and is distinguished from Symphyta by the narrow "waist" (petiole) formed between the first two segments of the actual abdomen; the first abdominal segment is fused to the thorax, and is called the propodeum. Therefore, it is general practice, when discussing the body of an apocritan in a technical sense, to refer to the mesosoma and metasoma rather than the "thorax" and "abdomen", respectively. The evolution of a constricted waist was an important adaption for the parasitoid lifestyle of the ancestral apocritan, allowing more maneuverability of the female's ovipositor. The ovipositor either extends freely or is retracted, and may be developed into a stinger for both defense and paralyzing prey. Larvae are legless and blind, and either feed inside a host or in a nest cell provisioned by their mothers.
The superfamily Ichneumonoidea contains the two largest families within Hymenoptera: Ichneumonidae and Braconidae. The group is thought to contain as many as 100,000 species, many of which have not yet been described. Like other parasitoid wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, now known to be paraphyletic.
The Vespoidea are a superfamily of wasps in the order Hymenoptera, although older taxonomic schemes may vary in this categorization, particularly in their recognition of a now-obsolete superfamily Scolioidea, as well as the relationship to ants. Vespoidea includes wasps with a large variety of lifestyles; eusocial, social, and solitary habits, predators, scavengers, parasitoids, and some herbivores.
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps (Pompilidae) exclusively attack spiders.
The superfamily Siricoidea is an archaic group of the order Hymenoptera, consisting of six families of xylophagous sawflies. The group is well represented in early Tertiary and Mesozoic times, but a number of living taxa remain, including the family Anaxyelidae, which has recently been linked to this group. The female ovipositor is typically long and projects posteriorly, and is used to drill into wood.
Anaxyelidae is a family of incense cedar wood wasps in the order Hymenoptera. There are about 13 genera in Anaxyelidae, all extinct except Syntexis, which has only a single species.
Cephoidea is a small superfamily within the Symphyta, commonly referred to as stem sawflies, containing some 100 species in 10 genera in the living family, Cephidae, plus another 10 genera in the extinct family Sepulcidae. Most species occur in the Northern Hemisphere, especially in Eurasia. The larvae are stem borers in various plants, especially grasses, but sometimes other herbaceous plants, shrubs, or trees. A few are pests of cereal grains. They are exceptionally slender for symphytans, often resembling other types of wasps, and they are the only Symphyta which lack cenchri. They are sometimes postulated to be the sister taxon to the Apocrita, though the Orussidae are more commonly considered such.
The Trigonalidae are one of the more unusual families of hymenopteran insects, of indeterminate affinity within the suborder Apocrita, and presently placed in its own superfamily, Trigonaloidea. The Trigonalidae are divided into two subfamilies, Orthogonalinae and Trigonalinae. These wasps are extremely rare, but surprisingly diverse, with some 90 species in over 15 genera, and are known from all parts of the world.
The superfamily Chrysidoidea is a very large cosmopolitan group, including many parasitoid or cleptoparasitic wasps. There are three large, common families and four small, rare families. Most species are small, almost never exceeding 15 mm. This superfamily is traditionally considered to be the basal taxon within the Aculeata, and, as such, some species can sting, though the venom is harmless to humans.
Maaminga is a genus of parasitic wasps containing two species and constituting the family Maamingidae. Discovered, and so far only known from New Zealand, the first two named species are Maaminga marrisi and M. rangi. The genus name derives from the Māori word "māminga", simply translated as "trickster" as the species evaded discovery for so long.
Cephidae is a family of stem sawflies in the order Hymenoptera. There are about 27 genera and more than 160 described species in Cephidae.
Andrena krigiana is a species in the family Andrenidae, in the order Hymenoptera. The species is known generally as the "dwarf-dandelion andrena". It is found in North America.
Eremnophila aureonotata is a species in the family Sphecidae, in the order Hymenoptera.
Heloridae is a family of wasps in the order Hymenoptera. There is at least one genus, Helorus, and at least two described species in Heloridae.
Vanhorniidae is a family parasitic wasps in the order Hymenoptera. There is at least one genus, Vanhornia, and at least one described species, Vanhornia eucnemidarum, in Vanhorniidae.
Pompiloidea is a superfamily that includes spider wasps and velvet ants, among others. in the order Hymenoptera. There are at least 5 families and 290 described species in Pompiloidea.
Tiphioidea is a suggested superfamily of stinging wasps in the order Hymenoptera. There are two families in Tiphioidea, Tiphiidae and Sierolomorphidae.
