Alexandr Pavlovich Rasnitsyn is a Russian entomologist, expert in palaeoentomology, and Honored Scientist of the Russian Federation (2001). His scientific interests are centered on the palaeontology, phylogeny, and taxonomy of hymenopteran insects and insects in general. He has also studied broader biological problems such as evolutionary theory, the principles of phylogenetics, taxonomy, nomenclature, and palaeoecology. He has published over 300 articles and books in several languages. In August 2008 he was awarded the Distinguished Research Medal of the International Society of Hymenopterists.
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.
Guyotemaimetsha is an extinct genus of wasp which existed in France during the Cretaceous period. The only species is Guyotemaimetsha enigmatica.
Maimetsha arctica is an extinct genus of wasp which existed during the Cretaceous period, and the only species in the genus Maimetsha.
Cretogonalys is an extinct genus of wasp which existed in Siberia during the late Cretaceous period, containing a single species, Cretogonalys taimyricus. It was described by Rasnitsyn in 1977.
Afrapia is an extinct genus of wasp which existed in Botswana during the late Cretaceous period. It contains the species Afrapia globularis and Afrapia variicornis.
Afromaimetsha robusta is an extinct species of wasp which existed in Botswana during the late Cretaceous period, and the only species in the genus Afromaimetsha.
Maimetshorapia is an extinct genus of wasp which existed in Botswana during the late Cretaceous period, containing the single species Maimetshorapia africana.
Plumalexius is a genus of wasps in the extinct monotypic family Plumalexiidae, containing two species: the type species Plumalexius rasnitsyni, known from the Late Cretaceous White Oaks Pit in Sayreville, New Jersey, and Plumalexius ohmkuhnlei, known from the Cretaceous Burmese amber.
Praeichneumon is an extinct genus of ichneumon wasps from the Lower Cretaceous of Mongolia and the Russian region of Transbaikalia. It was originally described by Alexandr Pavlovich Rasnitsyn in 1983, who also added a second species in 1990. Three new species were described by D. S. Kopylov in 2012.
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.
Serphitidae is a family of microscopic parasitic wasps known from the Cretaceous period.
Aptenoperissus is a genus of extinct wasp with eight described species, placed into the monotypic family Aptenoperissidae. The type species Aptenoperissus burmanicus resembles a mix between a grasshopper, an ant, and a wasp. It was described by a group of researchers from Oregon State University in a paper released online in October 2016. The piece of 100 million year old Burmese amber that it was preserved in was found in the Hukawng Valley of Myanmar in Southern Asia. A new family, Aptenoperissidae, was described to accommodate this insect. Species of Aptenoperissus were wingless, with a strong stinger. The creature had long legs making it capable of jumping higher than most insects. Subsequently additional species were described from the Myanmar amber: A. amabilis, A. delicatus, A. formosus, A. etius, A. magnifemoris, A. pusillus and A. zonalis. Initially placed in Ceraphronoidea, later studies placed it in Stephanoidea.
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.,)
2018 in paleoentomology is a list of new fossil insect taxa that were described during the year 2018, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
2015 in paleoentomology is a list of new fossil insect taxa that were described during the year 2015, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
Angarosphecidae is an extinct family of Mesozoic and early Cenozoic wasps in the superfamily Apoidea.
Panguidae is an extinct family of aculeate wasps. It has two unambiguous members, Protopangu known from the Early Cretaceous amber from the Wessex Formation of southern England and Pangu from the mid-Cretaceous Burmese amber of Myanmar. The genus Prosphex, originally considered incertae sedis, was suggested to be a member of the family in a later publication. Their relationships with other aculates are uncertain, and they are considered to be the only members of the superfamily Panguoidea. A specimen of Prosphex was observed with a substantial amount of angiosperm pollen near and within its mouth, implying that it was pollenivorous, and acted as a pollinator for flowering plants. However, other later publications have placed Prosphex outside of Panguidae.
Embolemopsis is an extinct genus of wasps belonging to the family Embolemidae. Two species are known: the type species, E. baissensis from the Aptian Zaza Formation of Russia, and E. maryannae from the Barremian Wessex Formation of England.
