Atypidae
Atypidae, also known as atypical tarantulas or purseweb spiders, is a spider family containing only three genus, 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 Mygalomorphae, mygalomorph spiders found in Central Europe. Biology ''Atypus'' builds a spider silk, 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. ''Calommata'' species, instead ...

Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3,000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to their creation of 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 realised that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the ...

Atypus
''Atypus'', also called purseweb spiders, is a genus of atypical tarantulas first described by Pierre André Latreille in 1804. It occurs in Eurasia, with one species (''A. affinis'') reaching into North Africa. Only three of the described species occur in Europe: ''A. piceus'', ''A. affinis'', and ''A. muralis''. Specimens from the USA formerly known as ''A. snetsingeri'' represent an introduced population of ''A. karschi''. 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). ''Atypus'' cobwebs have also been used in Sichuan and Tibet to manage the symptoms of diabetes. Identification features They are three-clawed, medium to large spiders with eight eyes. They have six spinnerets with the median spinneret truncated. The prolateral sides of t ...

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. Species it contains seven species in the United States, Canada, and Mexico: *'' Sphodros abboti'' Walckenaer, 1835 (type) – Southern Georgia, Northern Florida *'' Sphodros atlanticus'' Gertsch & Platnick, 1980 – Eastern and Central United States *'' Sphodros coylei'' Gertsch & Platnick, 1980 – South Carolina, Virginia *'' Sphodros fitchi'' Gertsch & Platnick, 1980 – Nebraska, Kansas, Oklahoma, Arkansas, Iowa *'' Sphodros niger'' ( Hentz, 1842) – Canada, Northeastern United States (south to Tennessee and east to Kansas) *'' Sphodros paisano'' Gertsch & Platnick, 1980 – Southeastern Texas, Mexico *''Sphodros rufipes ''Sphodros rufipes'', sometimes called the red legged purseweb spider, is a mygalomorph spider from the southern and eastern United States, though it has been photographed as far nort ...

Atypus Affinis
''Atypus affinis'', the purseweb spider, is a mygalomorph spider from Europe and North Africa. Distribution ''A. affinis'' is found throughout much of the European mainland, in Great Britain and in North Africa, where this fossorial spider typically inhabit dry heathland, open pine forest, meadows, grassland and the base of rocky outcrops. It is the only mygalomorph spider in the Nordics and the United Kingdom, but this species, which prefers relatively warm temperatures, is uncommon and localised in both those regions at the northern edge of its range. In the Nordics, it is only found on south-facing slopes in the southern part, where it is highly local but fairly widespread in Denmark and highly local in southern Sweden (Blekinge and Scania). In the United Kingdom, where the species is local and has declined, most records are from southern England, but it also ranges into Wales and north to far southwestern Scotland. It was formerly listed for Ireland, which was based on the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atypus Karschi
''Atypus karschi'' is a mygalomorph spider found in Korea, China, Taiwan, and Japan. It has been introduced into the United States. First described in 1887 by Friedrich Karl Wilhelm Dönitz, the specific name honors arachnologist Friedrich Karsch. Distribution Primarily found in Asia, there is also a population of A. karschi in southeastern Pennsylvania. This population was previously thought to be a separate species, but genetic testing revealed it to be the same species as A. karschi in Asia. Their habitat includes fields, trees, and slopes among wooded areas, suburban areas, and riparian zones. Description These spiders are black or dark brown and range from . They have large chelicerae The chelicerae () are the arthropod mouthparts, mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated ... in comparison to their body size, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atypus Piceus
''Atypus piceus'' is a mygalomorph spider of the family Atypidae. It occurs from France to Russia and in 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 A spinneret is a silk-spinning organ of a spider or the larva of an insect.

Sphodros Rufipes
''Sphodros rufipes'', sometimes called the red legged purseweb spider, is a mygalomorph spider from the southern and eastern United States, though it has been photographed as far north as Minnesota. It has confirmed sightings in Indiana, Missouri, New Jersey, West Virginia, Tennessee, Delaware, Louisiana, and Tuckernuck Island in Massachusetts. One recent sighting shows that these spiders can also be found in Canada, while another reveals that they have been spotted in Kansas. The species name ''rufipes'' is Latin for 'red foot'. Taxonomy The species was first described as ''Atypus rufipes'' by Pierre André Latreille in 1829. It was transferred to the genus '' Sphodros'' in 1980. ''Sphodros'' and ''Atypus'' species can be distinguished by features of their genitalia. ''Sphodros'' males have a long, curved embolus lying in a similarly shaped conductor. Females have an epigynum with four long, coiled tubes. Description These spiders are solid and strong-looking with reddish-b ...
