Paracharon caecus Hansen, 1921 | |
Paracharon is a genus of tailless whip scorpion. A single species, Paracharon caecus has been described. It is endemic to Guinea-Bissau in West Africa [1] It is one of two living genera of the family Paracharontidae, alongside the South American Jorottui . [2] It is a troglobite having no eyes, with P. caecus found living in termite nests. [3] [4]
Arachnida is a class of joint-legged arthropods, in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons.
Amblypygi is an order of arachnid chelicerate arthropods also known as whip spiders or tailless whip scorpions. The name "amblypygid" means "blunt tail", a reference to a lack of the flagellum that is otherwise seen in whip scorpions. Amblypygids possess no silk glands or venomous fangs. They rarely bite if threatened, but can grab fingers with their pedipalps, resulting in thorn-like puncture injuries.
Schizomida, also known as sprickets or short-tailed whip-scorpions, is an order of arachnids, generally less than 5 millimetres (0.20 in) in length. The order is not yet widely studied. E. O. Wilson has identified schizomids as among the "groups of organisms that desperately need experts to work on them."
Uropygi is an arachnid order comprising invertebrates commonly known as whip scorpions or vinegaroons. They are often called uropygids. The name "whip scorpion" refers to their resemblance to true scorpions and possession of a whiplike tail, and "vinegaroon" refers to their ability when attacked to discharge an offensive, vinegar-smelling liquid, which contains acetic acid. The order may also be called Thelyphonida. Both names, Uropygi and Thelyphonida, may be used either in a narrow sense for the order of whip scorpions, or in a broad sense which includes the order Schizomida.
Ricinulei is a small order of arachnids. Like most arachnids, they are predatory, eating small arthropods. They occur today in west-central Africa (Ricinoides) and the Americas as far north as Texas. As of 2021, 91 extant species of ricinuleids have been described worldwide, all in the single family Ricinoididae. In older works they are sometimes referred to as Podogona. Due to their obscurity they do not have a proper common name, though in academic literature they are occasionally referred to as hooded tickspiders.
Begoniaceae is a family of flowering plants with two genera and about 2040 species occurring in the subtropics and tropics of both the New World and Old World. All but one of the species are in the genus Begonia. There have been many recent discoveries of species in the genus Begonia, such as Begonia truncatifolia which is endemic to San Vincente, Palawan. B. truncatifolia is smaller in size than other species of the genus Begonia and this new species is proposed Critically Endangered by standards set by the IUCN. The only other genus in the family, Hillebrandia, is endemic to the Hawaiian Islands and has a single species. Phylogenetic work supports Hillebrandia as the sister taxon to the rest of the family. The genus Symbegonia was reduced to a section of Begonia in 2003, as molecular phylogenies had shown it to be derived from within that genus. Members of the genus Begonia are well-known and popular houseplants.
Plesiosiro is an extinct arachnid genus known exclusively from nine specimens from the Upper Carboniferous of Coseley, Staffordshire, United Kingdom. The genus is monotypic, represented only by the species Plesiosiro madeleyi described by Reginald Innes Pocock in his important 1911 monograph on British Carboniferous arachnids. It is the only known member of the order Haptopoda.
Charinidae is an arachnid family within the order of tailless whip scorpions.
Mastigoproctus giganteus, the giant whip scorpion, also called the giant vinegaroon or grampus, is a species of whip scorpions in the family Thelyphonidae.
Herbert Walter Levi was professor emeritus of zoology and curator of arachnology at the Museum of Comparative Zoology, Harvard University. He was born in Germany, and was educated there and at Leighton Park School, Reading in England. He then received his higher education at the University of Connecticut and the University of Wisconsin. Levi authored about 150 scientific papers on spiders and on biological conservation. He is the author of the popular Golden Guide Spiders and their Kin, with Lorna Rose Levi and Herbert Zim.
Phrynus is a genus of whip spiders found in tropical and subtropical regions, mostly in the new world.
Paraphrynus is a genus of whip spiders, also known as tailless whip scorpions, of the family Phrynidae. It is distributed from the southwestern United States to Central America, including several Caribbean islands. Most species are endemic to Mexico.
Phrynidae is a family of amblypygid arachnida arthropods also known as whip spiders and tailless whip scorpions. Phrynidae species are found in tropical and subtropical regions in North and South America. Some species are subterranean; all are nocturnal. At least some species of Phrynidae hold territories that they defend from other individuals.
Sarax is a genus of amblypygids of the family Charinidae.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
Weygoldtina is an extinct genus of tailless whip scorpion known from Carboniferous period, and the only known member of the family Weygoldtinidae. It is known from two species described from North America and England and originally described in the genus Graeophonus, which is now considered a nomen dubium.
Weygoldtia is a genus of amblypygids of the family Charinidae, described in 2018 by Gustavo Silva de Miranda, Alessandro P.L. Giupponi, Lorenzo Prendini and Nikolaj Scharff. The genus is named after the German arachnologist Peter Weygoldt, in recognition of his contributions to the study of Amblypygi.
Paracharontidae is an arachnid family within the order Amblypygi. Paracharontidae and the extinct Weygoldtinidae from the Carboniferous form the suborder Paleoamblypygi, the sister group to the remaining Amblypygi. The family contains two genera: Paracharon, containing the single species Paracharon caecus Hansen, 1921 from Guinea-Bissau in West Africa, and Jorottui with the single species Jorottui ipuanai from Colombia in northern South America. Paracharonopsis from the Eocene (Ypresian) aged Cambay amber of India was initially assigned to this family but this was later questioned and it has since been reassigned to Euamblypygi. Both living species are troglobites, having no eyes, with P. caecus living in termite nests, while J. ipuanai inhabits caves.
Catageus is a genus of amblypygids of the family Charontidae.
