The Mymaridae, commonly known as fairyflies or fairy wasps, are a family of chalcidoid wasps found in temperate, subtropical, and tropical regions throughout the world. The family contains around 100 genera with 1,400 species.
The Mymarommatidae, sometimes referred to as false fairy wasps, are a very small family of microscopic parasitic wasps. Only about half of the known species are living taxa, but they are found worldwide.
The Mymarommatoidea are a very small superfamily of microscopic fairyfly-like parasitic wasps. It contains only a single living family, Mymarommatidae, and three other extinct families known from Cretaceous aged amber. Less than half of all described species are living taxa, but they are known from all parts of the world. Undoubtedly, many more await discovery, as they are easily overlooked and difficult to study due to their extremely small size.
Pelecinidae is a family of parasitic wasps in the superfamily Proctotrupoidea. It contains only one living genus, Pelecinus, with three species known from the Americas. The earliest fossil species are known from the Jurassic, and the group was highly diverse during the Cretaceous. Members of Pelecinus are parasitic on larval beetles, flies, green lacewings, and sawflies.
The Stephanidae, sometimes called crown wasps, are a family of parasitoid wasps. They are the only living members of the superfamily Stephanoidea. Stephanidae has at least 345 living species in 11 genera. The family is considered cosmopolitan in distribution, with the highest species concentrations in subtropical and moderate climate zones. Stephanidae also contain four extinct genera described from both compression fossils and inclusions in amber.
Megalyroidea is a small hymenopteran superfamily of wasps that includes a single family, Megalyridae, with eight extant genera and 49 described species. Modern megalyrids are found primarily in the southern hemisphere, though fossils have only been found in the northern hemisphere. The most abundant and species-rich megalyrid fauna is in Australia. Another peak of diversity appears to be in the relict forests of Madagascar, but most of these species are still undescribed.
Rotoita basalis is a small parasitic wasp in the relictual family Rotoitidae. It is known only from New Zealand, and its closest known living relative is endemic to Chile.
Serphitidae is a family of microscopic parasitic wasps known from the Cretaceous period.

Discoscapa apicula is an extinct species of crabronid wasp, formerly considered one of the two oldest-known species of bees. The species was described from an amber inclusion in Burmese Amber in 2020 by George Poinar Jr., a zoologist at Oregon State University. The fossil was found in a mine in the Hukawng Valley of northern Myanmar and is believed to date from the Cretaceous Period, 100 million years ago, the same age as Melittosphex burmensis, likewise previously considered the oldest known bee species; as it comes from the same amber deposit, these two specimens are considered to be the same approximate age. More recent research has concluded that D. apicula is a wasp belonging to the subfamily Crabroninae, placed in its own tribe, Discoscapini.
Baeomorpha is an extinct genus of rotoitid parasitic wasp, known from the Late Cretaceous of Laurasia. The type species, B. dubitata was named by Charles Thomas Brues for a specimen found in 72 million year old Canadian Amber. The vast majority of species are known from the Russian Taimyr amber, of upper Santonian age but two species are known from the upper Campanian Canadian amber, while one species is known from the lower Cenomanian Burmese amber.

Pelecinellidae is a small family of chalcidoid wasps, formerly treated as the subfamily Leptofoeninae within Pteromalidae. They, like many small chalcidoids, are brilliantly metallic.
