Tityinae
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera ('' Ananteris'', '' Centruroides'', ''Compsobuthus'', or '' Tityus'') are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a osmopolitandistribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837. Around 20 species of medically important (meaning potentially lethal to humans) scorpions are known, and all but one of these (''Hemiscorpius lepturus'') are members of the Buthidae. In dead specimens, the spine beneath the stinger, characteristic for this family, can be observed.

Tityus (genus)
''Tityus'' is a large genus of thick-tailed scorpions (family (biology), family Buthidae), the namesake of its subfamily Tityinae. As of 2021, ''Tityus'' contains more than 220 described species distributed in Central America and South America, from Costa Rica to Argentina. Species in the genus ''Tityus'' have been studied for hundreds of years, long before the taxonomic classification was put in place. ''Tityus'' tend to be of medium size for scorpions, roughly 50 to 70 millimeters long. They are dark brown or red in color, and can exhibit sexual dimorphism. They can live in a variety of environments, ranging from urban to arid mountains to the Amazon Rainforest. ''Tityus'' scorpions are best known for their venom and potent sting. The genus contains several dangerously venomous scorpions, the best known of which is the Brazilian yellow scorpion, ''Tityus serrulatus, T. serrulatus''. Its venom can cause severe illness (including pancreatitis), and in the young, old and infirm ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apistobuthus
''Apistobuthus'' is a genus of scorpions in the family Buthidae. It was described by Susan Finnegan in 1932, and was for a long time considered to be monotypic, containing the single species '' A. pterygocercus''. In 1998, a second species, '' A. susanae'', was described by Wilson Lourenço; its specific epithet commemorates Susan Finnegan. ''A. susanae'' differs from ''A. pterygocercus'' in having stouter legs and pedipalp Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and ...s, among other characteristics. References Buthidae {{Scorpion-stub ...

Androctonus
Fattail scorpion or fat-tailed scorpion is the common name given to scorpions of the genus ''Androctonus'', one of the most dangerous groups of scorpion species in the world.Hendrixson, B. E. 2006. Buthid scorpions of Saudi Arabia, with notes on other families (Scorpiones: Buthidae, Liochelidae, Scorpionidae). In W. Büttiker, F. Krupp, I. Nader & W. Schneider (eds.), Fauna of Arabia (pp. in press, ~100 pages). Basel, Switzerland: Karger Libri. The genus was first described in 1828 by Christian Gottfried Ehrenberg. They are found throughout the semi-arid and arid regions of the Middle East and Africa. They are moderate sized scorpions, attaining lengths of 10 cm (just under 4 in). Their common name is derived from their distinctly fat metasoma, or tail, while the Latin name originates from Greek and means "man killer". Their venom contains powerful neurotoxins and is especially potent. Stings from ''Androctonus'' species are known to cause several human deaths each ...

Afrolychas
''Afrolychas'' is a genus of scorpion in the family Buthidae. There are two species in this genus, both of which used to belong to the genus ''Lychas''. The genus was described in 2019 by František Kovařík. The genus name ''Afrolychas'' is a reference to the African range of its species and the fact that the two species used to be members of the genus ''Lychas''. ''Afrolychass closest relatives are believed to be the scorpions in the genus '' Pseudolychas''. '' Afrolychas braueri'' is one of the rarest scorpions in the world, as it is listed as critically endangered on the IUCN Red List.
