Scotina
''Scotina'' is a genus of sac spiders of the family Liocranidae which was named by the German zoologist Franz Anton Menge in 1873 with '' Scotina gracilipes'' as the type species. ''Scotina'' was thought to be a mainly Western Palearctic genus but one species, ''Scotina palliardi'' was found in Korea in 2011. The species in the genus ''Scotina'' are small spiders which have six to ten pairs of ventral spines which can be seen using a lens. They have a darker and shinier cephalothorax than in other genera within the Liocranidae. They also have light brown femora with the more distal segments of the legs are darker, especially on the first pairs. They are terrestrial Terrestrial refers to things related to land or the planet Earth, as opposed to extraterrestrial. Terrestrial may also refer to: * Terrestrial animal, an animal that lives on land opposed to living in water, or sometimes an animal that lives on o ... spiders which are mainly found among moss and litter on the ground ...

Liocranidae
Liocranidae is a family of araneomorph spiders first described by Eugène Simon in 1897. They are one of several groups called "sac spiders". The holarctic genus '' Agroeca'' is the best-known, but it also includes various genera of more obscure spiders that still lack a diagnosis. Two species in the North American genus ''Neoanagraphis'' are found in the extremely dry conditions in the Mojave, Sonoran and Chihuahuan deserts. Females live in animal burrows while males wander and are the ones most often caught in pitfall traps. Genera , the World Spider Catalog accepts the following genera: *'' Agraecina'' Simon, 1932 — Europe, Africa, Kazakhstan *'' Agroeca'' Westring, 1861 — Asia, Europe, Africa, South America, North America *'' Andromma'' Simon, 1893 — Africa *'' Apostenus'' Westring, 1851 — Africa, United States, Europe *'' Arabelia'' Bosselaers, 2009 — Greece, Turkey *'' Argistes'' Simon, 1897 — Sri Lanka *'' Coryssiphus'' Simon, 1903 — South Africa *'' ...

Anton Menge
Franz Anton Menge (15 February 1808 in Arnsberg – 27 January 1880 in Danzig) was a German entomologist. Menge was a student of Physics, Chemistry and Natural history, Natural History at the University of Bonn He became professor at the Petrischule in Danzig. Menge published ''Preussische Spinnen'' or ''Spiders of Prussia'' between 1866 and 1878. His collection of insects and spiders is in the State Natural History Museum in Gdańsk. It includes many fossil insects preserved in Baltic amber. Works * ''Catalogus plantarum phanerogamicarum regionis Grudentinensis et Gedanensis''. Typis C. G.

Cephalothorax
The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind. (The terms ''prosoma'' and ''opisthosoma'' are equivalent to ''cephalothorax'' and ''abdomen'' in some groups. The terms ''prosoma'' and ''opisthosoma'' may be preferred by some researchers in cases such as arachnids, where there is neither fossil nor embryonic evidence animals in this class have ever had separate heads and thoraxes, and where the ''opisthosoma'' contains organs atypical of a true ''abdomen'', such as a heart and respiratory organs.) The word ''cephalothorax'' is derived from the Greek words for head (, ') and thorax (, '). This fusion of the head and thorax is seen in chelicerates and crustaceans; in other groups, such as the Hexapoda (including insect Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Carl Christian Koch
Ludwig Carl Christian Koch (8 November 1825 – 1 November 1908) was a German entomologist and arachnologist. He was born in Regensburg, Germany, and died in Nuremberg, Germany. He studied in Nuremberg, initially law, but then turned to medicine and science. From 1850, he practiced as a physician in the Wöhrd district of Nuremberg. He is considered among the four most influential scientists on insects and spiders in the second half of the 19th century. He wrote numerous works on the arachinoids of Europe, Siberia, and Australia. His work earned him worldwide reputation as "Spider Koch". Sometimes confused with his father Carl Ludwig Koch (1778–1857), another famous arachnologist, his name is abbreviated L.Koch on species descriptions; his father's name is abbreviated C.L.Koch Pierre Bonnet.

Evolution Of Spiders
Spiders have existed since at least 380 million years. The group's origins lie within an arachnid sub-group defined by the presence of book lungs (the tetrapulmonates); the arachnids as a whole evolved from aquatic chelicerate ancestors. More than 45,000 extant species have been described, organised taxonomically in 3,958 genera and 114 families. There may be more than 120,000 species. Fossil diversity rates make up a larger proportion than extant diversity would suggest with 1,593 arachnid species described out of 1,952 recognized chelicerates. Both extant and fossil species are described annually by researchers in the field. Major developments in spider evolution include the development of spinnerets and silk secretion. Early spider-like arachnids Among the oldest known land arthropods are Trigonotarbids, members of an extinct order of spider-like arachnids. Trigonotarbids share many superficial characteristics with spiders, including a terrestrial lifestyle, respiration throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Spider Catalog
The World Spider Catalog (WSC) is an online searchable database concerned with spider taxonomy. It aims to list all accepted families, genera and species, as well as provide access to the related taxonomic literature. The WSC began as a series of web pages in 2000, created by Norman I. Platnick of the American Museum of Natural History. After his retirement in 2014, the Natural History Museum of Bern took over, converting the catalog to a relational database A relational database (RDB) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. A Relational Database Management System (RDBMS) is a type of database management system that stores data in a structured for .... As of November 22, 2024, 52'487 species are listed, after an average discovery rate of three new species per day. The order Araneae has the seventh-most species of all orders. The WSC's existence makes spiders the largest taxon with an online listing that is updated regular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Palearctic
The Western Palaearctic or Western Palearctic is part of the Palaearctic realm, one of the eight biogeographic realms dividing the Earth's surface. Because of its size, the Palaearctic is often divided for convenience into two, with Europe, North Africa, northern and central parts of the Arabian Peninsula, and part of temperate Asia, roughly to the Ural Mountains forming the western zone, and the rest of temperate Asia becoming the Eastern Palaearctic. Its exact boundaries differ depending on the authority in question, but the '' Handbook of the Birds of Europe, the Middle East, and North Africa: The Birds of the Western Palearctic'' (''BWP'') definition is widely used, and is followed by the most popular Western Palearctic checklist, that of the Association of European Rarities Committees (AERC). The Western Palearctic realm includes mostly boreal and temperate climate ecoregions. The Palaearctic region has been recognised as a natural zoogeographic region since Sclater propo ...

John Blackwall
John Blackwall (20 January 1790 – 11 May 1881) was an English naturalist with a particular interest in spiders. Life Blackwall was born in Manchester on 20 January 1790. He lived at Hendre House near Llanrwst in north Wales from 1833 until his death. He was interested in nature from an early age, first in birds and then spiders, on which he published his first article in 1827. He published ''A History of the Spiders of Great Britain and Ireland'' (2 volumes, 1861–1864, Ray Society), which included accounts of 304 species and gave the first adequate descriptions of British spiders. Ten of the plates included were by Octavius Pickard-Cambridge and twelve were by the Irish naturalist Robert Templeton. He died 11 May 1881. Correspondence with Charles Darwin Blackwall wrote four letters on the subject of spiders to Charles Darwin, dated 12 February 1868, 18 February 1868, 10 August 1869 and 8 September 1869. They survive in the Darwin Archive at Cambridge University Library ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
