The Scoliidae, the scoliid wasps, are a family of wasps comprising about 560 species 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 many of the Tiphiidae and Thynnidae.
Horntail or wood wasp are any of the 150 non-social species of the hymenopteran family Siricidae, a type of wood-eating sawfly. The common name "horntail" derives from the stout, spine-like structure at the end of the adult's abdomen, which is used to pierce the host's bark to allow the eggs to be inserted into the wood. A typical adult horntail is brown, blue, or black with yellow or red parts, and may often reach up to 4 cm (1.6 in) long. The pigeon horntail can grow up to 5 cm (2.0 in) long, among the longest of all Hymenoptera.
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.
The Orussidae or the parasitic wood wasps represent a small family of sawflies ("Symphyta"). Currently, about 93 extant and four fossil species are known. They take a key position in phylogenetic analyses of Hymenoptera, because they form the sister taxon of the megadiverse apocritan wasps, and the common ancestor of Orussidae + Apocrita evolved parasitism for the first time in course of the evolution of the Hymenoptera. They are also the only sawflies with carnivorous larvae.
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 Xyelidae are a comparatively species-poor family of sawflies, comprising about 80 extant species in five genera worldwide, and is the only family in the superfamily Xyeloidea. The fossil record of the family is extensive, comprising more than 120 species and including the oldest fossil Hymenoptera species dating back to the Triassic, between 245 and 208 million years ago. Xyelidae are to be regarded as living fossils since they represent one of the oldest lineages of insects and include still extant forms.
Cephoidea is a small superfamily within the Symphyta, commonly referred to as stem sawflies, containing some 100 species in 10 genera in the living family, Cephidae, plus another 17 genera in the extinct family Sepulcidae. They first appeared around 212 million years ago in the Norian Age, and are diurnal. Most species occur in the Northern Hemisphere, especially in Eurasia. The larvae are stem borers in various plants, especially grasses, but sometimes other herbaceous plants, shrubs, or trees. A few are pests of cereal grains. They are exceptionally slender for symphytans, often resembling other types of wasps, and they are the only Symphyta which lack cenchri. They are sometimes postulated to be the sister taxon to the Apocrita, though the Orussidae are more commonly considered such.
Trigonalidae is a family of parasitic wasps in the suborder Apocrita. They are the only living members of the superfamily Trigonaloidea. Trigonalidae are divided into 2 subfamilies; Orthogonalinae and Trigonalinae. These wasps are extremely rare, but surprisingly diverse, with over 90 species in 16 genera, and are known from all parts of the world. It is possibly the sister group to all Aculeata.
The Andaikhudag Formation, in older literature referred to as Unduruh Formation or Ondorukhaa Formation, is an Early Cretaceous geologic formation in Mongolia. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
Sepulcidae is an extinct family of stem sawflies in the order Hymenoptera. The family is known primarily from late Mesozoic fossils found in 1968 in Transbaikalia. The insects were distant relatives of modern sawflies and are part of the living superfamily Cephoidea.
Sepulkas, are fictional objects found in works The Star Diaries and Observation on the Spot, Stanisław Lem. A fictional encyclopedia lists them as "objects used for sepuling".
The I.I. Schmalhausen Institute of Zoology of National Academy of Sciences of Ukraine is the leading institution in Ukraine doing research in zoology. At present, this is the leading regional center of zoological research and expertise in the Eastern Europe.
Serphitidae is a family of microscopic parasitic wasps known from the Cretaceous period.
Agastomyrma is an extinct genus of formicid in the ant subfamily Myrmicinae known from the fossil species Agastomyrma laticeps found in eastern Asia.
Heloridae is a family of wasps in the order Hymenoptera known primarily from fossils, and only one extant genus, Helorus, with 12 species found worldwide. Members of Helorus are parasitic on green lacewings.
Sepulenia is an extinct genus of stem sawflies in the family Sepulcidae. There is one described species in Sepulenia, S. syricta.
Prosyntexis is an extinct genus of stem sawflies in the family Sepulcidae. There are at least four described species in Prosyntexis.
Neologisms constitute a notable part of the writing style of Stanisław Lem, a Polish science fiction author and essayist.
Konstantin Vasilyevich Dushenko is a Russian translator, culturologist and historian, with the Institute of Scientific Information on Social Sciences of the Russian Academy of Sciences. He authored over 30 books on the origins of various quotations, aphorisms, and bon mots.
