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. [1]
Deinodryinus areolatus is known only from a single fossil, the holotype, specimen number PIN No. 964/60, which is housed in the A.A. Borissiak Paleontological Institute, Russian Academy of Sciences, in Moscow. The specimen is composed of a fully complete adult female wasp. The specimen is preserved as an inclusion in a transparent chunk of amber. [1] The amber dates to between forty and forty-five million years old, and, being Baltic amber dispersed in the sea, a more specific type location than the Baltic region is not possible to identify. Deinodryinus areolatus was first studied by the Russian paleoentomologist Nadezdha Ponomarenko in 1975, with a redescription by paleoentomologists Adalgisa Guglielmino and Massimo Olmi, both of the University of Tuscia. Ponomarenko's 1975 type description of the new genus and species was published in the Russian journal Paleontologicheskiy Zhurnal , with the species placed by her into a new genus Electrodryinus. [1] Electrodryinus was subsequently synonymized with Deinodryinus in a 1984 paper by Massimo Olmi, resulting in the current binomial Deinodryinus areolatus. D. areolatus was the first of three Deinodryinus species to be described from the fossil record. Deinodryinus velteni is also known from a fossil preserved in Baltic amber, while Deinodryinus? aptianus is known only from a Mongolian compression fossil in marl. [1]
The holotype specimen is a complete adult female preserved with areas of the face, vertex, pronotum, scutellum and metanotum obscured. Overall the female is 4.5 millimetres (0.18 in) in length, with antennae that are less than three times the length of the head and macropterous hyaline wings. The antennae are composed of ten segments, densely hairy, and distinctly clavate, (club shaped) in structure. The mandibles have four teeth on each side, which progress from large to small. The tooth size changes in relation to the placement front to back on the mandible. The forewings have three cells at the base that are formed by pigmented veins. The forewings have a pterostigma that is approximately four times as long as it is wide, and a stigmal vein that is not S-shaped. The forelegs have a chelate structure, with the subapical tooth or other teeth. [1]
Sphecomyrma is an extinct genus of ants which existed in the Cretaceous approximately 79 to 92 million years ago. The first specimens were collected in 1966, found embedded in amber which had been exposed in the cliffs of Cliffwood, New Jersey, by Edmund Frey and his wife. In 1967, zoologists E. O. Wilson, Frank Carpenter and William L. Brown, Jr. published a paper describing and naming Sphecomyrma freyi. They described an ant with a mosaic of features—a mix of characteristics from modern ants and aculeate wasps. It possessed a metapleural gland, a feature unique to ants. Furthermore, it was wingless and had a petiole which was ant-like in form. The mandibles were short and wasp-like with only two teeth, the gaster was constricted, and the middle and hind legs had double tibial spurs. The antennae were, in form, midway between the wasps and ants, having a short first segment but a long flexible funiculus. Two additional species, S. canadensis and S. mesaki, were described in 1985 and 2005, respectively.
Fibla carpenteri is an extinct species of snakefly in the Inocelliidae genus Fibla. F. carpenteri is named in honor of the paleoentomologist Dr Frank Carpenter, for his vast knowledge and interest in Raphidioptera.
Palaeovespa is an extinct genus of wasp in the Vespidae subfamily Vespinae. The genus currently contains eight species, five from the Priabonian stage Florissant Formation in Colorado, United States two from the middle Eocene Baltic amber deposits of Europe. and one species from the late Paleocene of France.
Dryinus grimaldii is an extinct species of wasp in the dryinid genus Dryinus. The species is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola.
Dryinus rasnitsyni is an extinct species of wasp in the dryinid genus Dryinus. The species is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola.
Deinodryinus? aptianus is an extinct species of Deinodryinus in the wasp family Dryinidae. The species is solely known from a Cretaceous fossil found in Mongolia.
Deinodryinus velteni is an extinct species of Deinodryinus in the wasp family Dryinidae. The species is known solely from an Eocene fossil found in the Baltic region.
Arostropsis is an extinct genus of broad-nosed weevil in the beetle family Curculionidae known from an Upper Eocene fossil found in Europe. The genus contains a single described species, Arostropsis groehni.
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.
Brownimecia is an extinct genus of ants, the only genus in the tribe Brownimeciini and subfamily Brownimeciinae of the Formicidae. Fossils of the single identified species, Brownimecia clavata, are known from the Middle Cretaceous of North America. The genus is one of several ants described from Middle Cretaceous ambers of New Jersey. Brownimecia was initially placed in the subfamily Ponerinae, until it was transferred to its own subfamily in 2003; it can be distinguished from other ants due to its unusual sickle-like mandibles and other morphological features that makes this ant unique among the Formicidae. The ant is also small, measuring 3.43 millimetres (0.135 in), and a stinger is present in almost all of the specimens collected. The morphology of the mandibles suggest a high level of feeding specialization.
Haidomyrmex is an extinct genus of ants in the formicid subfamily Haidomyrmecinae, and is one of nine genera placed in the subfamily Haidomyrmecinae. The genus contains three described species Haidomyrmex cerberus, Haidomyrmex scimitarus, and Haidomyrmex zigrasi. All three are known from single Late Cretaceous fossils which have been found in Asia. H. cerberus is the type species and Haidomyrmex the type genus for the subfamily Haidomyrmecinae.
Pristomyrmex rasnitsyni is an extinct species of ant in the genus Pristomyrmex. The species is known from a single Late Eocene fossil which was found in Europe.

Usomyrma is an extinct genus of ant in the formicid subfamily Dolichoderinae. The genus contains a single described species, Usomyrma mirabilis, that is known from two Middle Eocene fossils which were found in Scandinavian amber in Denmark.

Thaumatodryinus tuukkaraski is a wasp species in the family Dryinidae. This tiny insect is endemic to Kenya where it is only known from the Taita Hills. In 2015, this newly discovered species was named in direct reference to former Boston Bruins (NHL) goaltender, Tuukka Rask.

Embolemidae is a family of small solitary parasitoid wasps with around 70 species in 2 genera distributed around the world. The few species whose biology is known are parasites on planthopper nymphs of the families Achilidae and Cixiidae. There is debate regarding the status of the genus named Ampulicomorpha by Ashmead in 1893, generally considered now to be a junior synonym of Embolemus (e.g.,), though some authorities dispute this (e.g.,)
