Wafer-lid Trapdoor Spider
The family Cyrtaucheniidae, known as wafer-lid trapdoor spiders, are a widespread family of Mygalomorphae spiders. Description Wafer-lid spiders are generally large and range in color between light brown and black. Their eyes are placed in two rows, either in a rectangular position or with the back row wider apart. They lack the thorn-like spines on tarsi and metatarsi I and II (the two outermost leg segments) found in true trapdoor spiders (Ctenizidae). Many, but not all, make wafer-like doors to their burrows, while others build the cork-like doors found commonly in the true trapdoor spiders. Distribution The family is well represented South America, and Africa. A currently undescribed genus in the western United States may hold an altitude record for the family, being found up to over . The genus ''Anemesia'' is found only in Central Asia, and ''Cyrtauchenius'' reaches from Algeria north to Italy, with one species found in the USA. ''Angka'' is endemic to the cloud ...

Euctenizidae
The Euctenizidae (formerly Cyrtaucheniidae subfamily Euctenizinae) are a family of mygalomorph spiders. They are now considered to be more closely related to Idiopidae. Etymology The name comes from the Greek prefix (''eu-''), meaning "valuable" or "good", which had been thought that the family Ctenizidae possess these traits.Bond, J. E., B. E. Hendrixson, C. A. Hamilton & M. Hedin. (Bond et al., 2012b) - ''A reconsideration of the classification of the spider infraorder Mygalomorphae (Arachnida: Araneae) based on three nuclear genes and morphology'' Biology Many, but not all, make wafer-like doors to their burrows, while others build the cork-like doors found commonly in the true trapdoor spiders. The biology of nearly all of the species is poorly known. Distribution The family occurs almost exclusively in the United States and Mexico. Common U.S. genera include ''Myrmekiaphila'', ''Aptostichus'' and '' Promyrmekiaphila''. Genera , the World Spider Catalog accepts the fo ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aptostichus Stanfordianus Male
''Aptostichus'' is a genus of North American mygalomorph spiders in the family Euctenizidae, and was first described by Eugène Simon in 1891. They are found predominantly in southern California, United States. Behavior Members of the North American genus, ''Aptostichus'', assemble tunnels with side chambers, but they do not close these chambers with additional trapdoors. Species it contains forty-one species in the United States and Mexico: *''Aptostichus aguacaliente'' Bond, 2012 – USA *'' Aptostichus angelinajolieae'' Bond, 2008 – USA *''Aptostichus anzaborrego'' Bond, 2012 – USA *''Aptostichus asmodaeus'' Bond, 2012 – USA *''Aptostichus atomarius'' Simon, 1891 (type) – USA *'' Aptostichus barackobamai'' Bond, 2012 – USA *''Aptostichus bonoi'' Bond, 2012 – USA *''Aptostichus cabrillo'' Bond, 2012 – USA, Mexico *''Aptostichus cahuilla'' Bond, 2012 – USA *''Aptostichus cajalco'' Bond, 2012 – USA *''Aptostichus chavezi'' Bond, 2012 – USA *''Aptosti ...

Spiders Described In 1908
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a ...
