Entychides Aurantiacus
''Entychides'' is a genus of mygalomorph trapdoor spiders in the family Euctenizidae, and was first described by Eugène Simon in 1888. Originally placed with the Ctenizidae, it was moved to the wafer trapdoor spiders in 1985, then to the Euctenizidae in 2012. Species it contains four species in Mexico, the Southwestern United States, and the Lesser Antilles: *''Entychides arizonicus'' Gertsch & Wallace, 1936 – USA *'' Entychides aurantiacus'' Simon, 1888 (type Type may refer to: Science and technology Computing * Typing, producing text via a keyboard, typewriter, etc. * Data type, collection of values used for computations. * File type * TYPE (DOS command), a command to display contents of a file. * ...) – Mexico *'' Entychides dugesi'' Simon, 1888 – Mexico *'' Entychides guadalupensis'' Simon, 1888 – Guadeloupe References Euctenizidae Mygalomorphae genera Spiders of North America Taxa named by Eugène Simon {{Euctenizidae-stub ...

Eugène Simon
Eugène Louis Simon (; 30 April 1848 – 17 November 1924) was a French naturalist who worked particularly on insects and spiders, but also on birds and plants. He is by far the most prolific spider Taxonomy (biology), taxonomist in history, describing over 4,000 species. Work on spiders His most significant work was ''Histoire Naturelle des Araignées'' (1892–1903), an encyclopedic treatment of the spider genera of the world. It was published in two volumes of more than 1000 pages each, and the same number of drawings by Simon. Working at the National Museum of Natural History (France), Muséum National d'Histoire Naturelle in Paris, it took Simon 11 years to complete, while working at the same time on devising a taxonomic scheme that embraced the known taxa. Simon described a total of 4,650 species, and as of 2013 about 3,790 species are still considered valid. The International Society of Arachnology offers a Simon Award recognising lifetime achievement. The Eocene fos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

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 ...

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 accept ...

Ctenizidae
Ctenizidae ( ) is a small family of mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation, and silk. They may be called trapdoor spiders, as are other, similar species, such as those of the families Liphistiidae, Barychelidae, and Cyrtaucheniidae, and some species in the Idiopidae and Nemesiidae. The name comes from the distinctive behavior of the spiders to construct trapdoors, and ambush prey from beneath them. In 2018, the family Halonoproctidae was split off from the Ctenizidae. A further genus, '' Stasimopus'', was split off into its own family, Stasimopidae, in 2020. The family currently consists of two genera and five species. Etymology The name derives from Greek ''ktenizein'', meaning "combing" or "cleaning", referring to their behaviour of cleaning continuously, and the suffix "-idae", which designates belonging to a family. Taxonomy The family Ctenizidae was first described by Thorell in 1887, being based on the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wafer 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 thornlike 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 fores ...
