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.
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015.
Electrinocellia is an extinct monotypic genus of snakefly in the family Inocelliidae containing the single species Electrinocellia peculiaris and known from Eocene aged Baltic amber.
Styporaphidia is a genus of snakefly, belonging to the extinct family Mesoraphidiidae, containing up to two species, the type species Styporaphidia magia and tentatively Styporaphidia? hispanica. The genus was named from the Greek stypos meaning "stem" or "stump" and Raphidia, the type genus for, and most often used as, a stem for generic names in the order Raphidioptera. The species name of S. magia is from the Greek word mageia meaning "magic" while the species name for S.? hispanica is from the Latin Hispania meaning "Spain" in reference to the type locality of the species.
Oligochlora is an extinct genus of sweat bee in the Halictidae subfamily Halictinae. The genus currently contains six species, all of which are known from the early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.
Leptofoenus pittfieldae is an extinct species of wasp in the family Pteromalidae. It is known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. The species is known from a single 8.8 millimetres (0.35 in) male specimen excavated from the La Toca mine group northeast of Santiago de los Caballeros in 2008 and deposited in the Insect Fossil Collection at the University of Kansas Natural History Museum in Lawrence, Kansas, where it was studied and described by Dr. Michael S. Engel. The species name pittfieldae honors Ms. Morgan Pittfield, niece of the specimen donor.
Termitaradus mitnicki is an extinct species of true bug in the family Termitaphididae known only from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.
Kachinus is an extinct genus of ant-like stone beetle in the family Staphylinidae containing the single species Kachinus antennatus.
Staphylininae are a subfamily of rove beetles. They contain the typical rove beetles with their long but fairly robust blunt-headed and -tipped bodies and short elytra, as well as some more unusually-shaped lineages.
Denaeaspis is an extinct genus of tortoise beetle in the family Chrysomelidae and containing a single species Denaeaspis chelonopsis. The species is known only from the Middle Eocene Parachute Member, part of the Green River Formation, in the Piceance Creek Basin, Garfield County, northwestern Colorado, USA.
Lebanoraphidia is an extinct genus of snakefly in the family Mesoraphidiidae. The genus is solely known from Cretaceous, Upper Neocomian, fossil amber found in Lebanon. Currently the genus is composed of a single species Lebanoraphidia nana.
Deinodryinus areolatus is an extinct species of Deinodryinus in the wasp family Dryinidae. The species is solely known from an Eocene fossil found in the Baltic region.
Astreptolabis is an extinct genus of earwig in the Dermaptera family Pygidicranidae known from a group of Cretaceous fossils found in Myanmar. The genus contains two described species, Astreptolabis ethirosomatia and Astreptolabis laevis and is the sole member of the subfamily Astreptolabidinae.
Tytthodiplatys is an extinct genus of earwig in the family Diplatyidae known from a Cretaceous fossil found in Myanmar. The genus contains a single described species, Tytthodiplatys mecynocercus.
Protostephanus is an extinct genus of crown wasp in the Hymenoptera family Stephanidae known from an Eocene fossil found in the United States of America. The genus contains a single described species, Protostephanus ashmeadi placed in the stephanid subfamily Stephaninae.
Zophotermes is an extinct genus of termite in the Isoptera family Rhinotermitidae known from two Eocene fossils found in India. The genus contains a single described species, Zophotermes ashoki placed in the subfamily Prorhinotermitinae.
Nanotermes is an extinct genus of termites in the Isoptera family Termitidae known from only one Eocene fossil found in amber of the Cambay Basin. The genus contains a single described species, Nanotermes isaacae placed tentatively in the subfamily Termitinae.
Parastylotermes is an extinct genus of termite in the Isoptera family Stylotermitidae known from North America, Europe, and India. The genus contains five described species, Parastylotermes calico, Parastylotermes frazieri, Parastylotermes krishnai, Parastylotermes robustus, and Parastylotermes washingtonensis.
Anochetus corayi is an extinct species of ant in the subfamily Ponerinae known from one possibly Miocene fossil found on Hispaniola. A. corayi is one of eight species in the ant genus Anochetus to have been described from fossils found in Dominican amber and is one of a number of Anochetus species found in the Greater Antillies.
Electrostephanus is an extinct genus of crown wasp in the hymenopteran family Stephanidae, and is the only genus placed in the subfamily Electrostephaninae. The genus contains four described species, E. brevicornis, E. neovenatus, E. janzeni, and E. petiolatus, placed in two subgenera E. (Electrostephanus) and E. (Electrostephanodes). Electrostephanus is known from several middle Eocene fossils which have been found in Europe.
