Atypidae
Atypidae, also known as atypical tarantulas or purseweb spiders, is a spider family containing only three genera. They are accomplished ambush predators that spend most of their time in a sock-like, silken retreat on the ground from where they kill their prey. Distribution '' Sphodros'' and '' Atypus'' occur in North America, while '' Atypus'' and '' Calommata'' occur in Asia and Africa. Only '' Atypus'' species are found in Europe. '' Atypus affinis'', '' Atypus muralis'', and '' Atypus piceus'' are the only mygalomorph spiders found in northwestern Europe. Biology ''Atypus'' builds a silken tube parallel to the surface of the ground. While up to 8 cm of the tube lie on the ground, about 20 cm are buried vertically. The spider rests at the bottom of the tube. When prey walks on the exposed part, the spider, alerted by the vibrations, stabs the prey through the silk, cuts the web and drags the prey inside to be eaten.

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to them forming trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realized that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the branching ...

Sphodros
''Sphodros'' is a genus of North American purseweb spiders first described by Charles Athanase Walckenaer in 1835. It was considered a synonym of ''Atypus'' until 1980.

Atypus
''Atypus'', also called purseweb spiders, is a genus of Atypidae, atypical tarantulas first described by Pierre André Latreille in 1804. It occurs in Eurasia, with one species (''A. affinis'') reaching into North Africa, and one species (''A. snetsingeri'') in the USA. Only three of the described species occur in Europe: ''A. piceus'', ''A. affinis'', and ''A. muralis''. Peasants in the southern Carpathian Mountains used to cut up tubes built by ''Atypus'' and cover wounds with the inner lining. It reportedly facilitated healing, and even connected with the skin. This is believed to be due to antiseptic properties of spider silk (which is made of protein). Identification features They are three-clawed, medium to large spiders with eight eyes. They have six spinneret (spider), spinnerets with the median spinneret truncated. The prolateral sides of the maxillae are elongated. The cephalic side of the cephalothorax is elevated. They have large chelicerae with long and thin fangs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atypus Piceus
''Atypus piceus'' is a mygalomorph spider of the family Atypidae. It occurs in Europe to Moldavia, and Iran and is the type species of the genus ''Atypus''. Description Males are about long without chelicerae, females up to . Males are of a deep black, while spiderlings and females are dark brown with a violet hue. The very long posterior spinnerets consist of three segments, the last segment features a light blot, which is helpful in identifying the species. ''A. piceus'' can live for more than 10 years.Bellmann, H. (1997). Kosmos-Atlas Spinnentiere Europas. ''Kosmos''. Habits Adults live in up to deep tubes with a diameter of about 10 mm. The silken lining continues above ground for about , where it is camouflaged with matter from the vicinity. The mating period is from June to July, when the males search for females. The spiderlings hatch during autumn and overwinter in the mother's burrow without feeding. After emerging in spring, they climb nearby plants and use stran ...

Atypus Affinis
''Atypus affinis'', the purseweb spider, is a common mygalomorph spider from Europe. Distribution It is found in Europe (Netherlands, Germany) and southern England, but ranging as far north as southern Sweden and as far south as North Africa. Its hidden lifestyle makes it a rarely seen species. It is the only British mygalomorph spider. The purse-web spider was previously known from Denmark, but as it had not been seen for 60 years despite persistent searching, it was considered extinct. In 1994, it was rediscovered in Jutland. Description These spiders are black or brownish and not particularly large; the males are about , while the females are larger at . They look much like ''Atypus piceus ''Atypus piceus'' is a mygalomorph spider of the family Atypidae. It occurs in Europe to Moldavia, and Iran and is the type species of the genus ''Atypus''.

Atypus Karschi
''Atypus karschi'' is a mygalomorph spider found in Korea, China, Taiwan, and Japan. It has been introduced into the United States. These spiders are black or dark brown and range from . Like other spiders in its infraorder, it has fangs that point straight down rather than crossing. This spider has an unusual web. It spins a tube of silk that is hidden partially underground, with the portion above ground being covered in leaves and other debris. The spider waits for an insect to land or crawl onto the tube, then bites through the silk to pull the insect inside. The specific name honors arachnologist Friedrich Karsch Ferdinand Anton Franz Karsch or Karsch-Haack (2 September 1853, in Münster – 20 December 1936, in Berlin) was a German arachnologist, entomologist and anthropologist. The son of a doctor, Karsch was educated at the Friedrich Wilhelm Unive .... References External links English site with general information on ''A. karschi'' {{Taxonbar, from=Q303804 ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
