Radiophron is an extinct genus of wasp which existed in Spain during the early Cretaceous period. [1] The only species is Radiophron ibericus. It is a member of the extinct family Radiophronidae.
The Scoliidae, the scoliid wasps, are a family of about 560 species found worldwide. They tend to be black, often marked with yellow or orange, and their wing tips are distinctively corrugated. Males are more slender and elongated than females, with significantly longer antennae, but the sexual dimorphism is not as apparent as in the Tiphiidae.
Rhopalosomatidae is a family of Hymenoptera containing about 68 extant species in four genera that are found worldwide. Three fossil genera are known.
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 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.
The Rotoitidae are a very small family of rare, relictual parasitic wasps in the superfamily Chalcidoidea, known primarily from fossils. Only two extant species are known, each in its own genus, one from New Zealand and one from Chile, and little is known about their biology. Females of the Chilean species, Chiloe micropteron, have their wings reduced to tiny bristles. Most fossil species are known from the Late Cretaceous (Santonian) Taimyr amber of Russia and Late Cretaceous (Campanian) Canadian amber, but one species, Baeomorpha liorum is known from the mid Creaceous Burmese amber.
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.
Stephanoidea is a superfamily of parasitic wasps within the Apocrita, it includes only one living family, Stephanidae, as well as the extinct families Ephialtitidae, Aptenoperissidae, Myanmarinidae and Ohlhoffiidae.
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.
Microcostaphron parvus is an extinct species of wasp belonging to the extinct family Radiophronidae which existed in Spain during the early Cretaceous period. Only a single specimen is known, which was found near Peñacerrada-Urizaharra in the Basque Country.
Spathiopterygidae is an extinct family of small parasitic wasps, known from the Cretaceous of Laurasia and Northern Gondwana. They are suggested to be members of Diaprioidea, in part due to their similarly reduced wing venation. Some members of the group reduced or lost the hindwings entirely.
Maimetshidae is an extinct family of wasps, known from the Cretaceous period. While originally considered relatives of Megalyridae, they are now considered to probably be close relatives of Trigonalidae.
Pleurosternidae is an extinct family of freshwater turtles belonging to Paracryptodira. They are definitively known from the Late Jurassic to Early Cretaceous (Albian) of Western Europe and North America.
Serphitidae is a family of microscopic parasitic wasps known from the Cretaceous period.
Pompiloidea is a superfamily that includes spider wasps and velvet ants, among others. in the order Hymenoptera. There are 4 families in Pompiloidea.
The Gallorommatidae is an extinct family of microscopic parasitoid wasps, belonging to the Mymarommatoidea. It is known from several species found in Cretaceous aged amber.
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.
Diversinitidae are an extinct family of Chalcid wasps. Three genera are known, all from the early Cenomanian aged Burmese amber. They are distinguished by the presence of multiporous plate sensilla on the first flagellomere in both sexes. They are among the most basal and earliest known members of Chalcidoidea.
Proterosceliopsis is an extinct genus of platygastroid parasitic wasp, known from the Mid-Cretaceous of Eurasia. The genus was first described in 2014 from the Albian amber of the Escucha Formation. In 2019 additional species were described from the Cenomanian-age Burmese amber, and was placed into the monotypic family Proterosceliopsidae.
Brodiechelys is an extinct genus of terrestrial turtle belonging to the family Xinjiangchelyidae. Remains of Brodiechelys dated back to the Early Cretaceous period, and have been found in the United Kingdom and Spain.
Radiophronidae is an extinct family of wasps known from two genera found in Cretaceous (Albian) aged amber from Spain. While originally classified in Ceraphronoidea, they were later considered to probably be members of Chrysidoidea.
