Aterigena
''Aterigena'' is a genus of Agelenidae, funnel weavers first described by A. Bolzern, A. Hänggi & D. Burckhardt in 2010. The name is an anagram of ''Tegenaria''. It was created in 2010 for a group of ''Tegenaria'' and ''Malthonica'' species that formed a clade in a Phylogenetics, phylogenetic analysis. The genus was later found to be Monophyly, monophyletic, further separating ''Eratigena'' from ''Tegenaria'' and ''Malthonica''. Species it contains five species: *''Aterigena aculeata'' (Wang, 1992) – China *''Aterigena aliquoi'' (Brignoli, 1971) – Italy (Sicily) *''Aterigena aspromontensis'' Bolzern, Hänggi & Burckhardt, 2010 – Italy *''Aterigena ligurica'' (Simon, 1916) (Type species, type) – France, Italy *''Aterigena soriculata'' (Simon, 1873) – France (Corsica), Italy (Sardinia) References Agelenidae Spiders of Asia Araneomorphae genera {{Agelenidae-stub ...

Eratigena
''Eratigena'' is a genus of spider in the family Agelenidae. Most of its species were moved from the genus ''Tegenaria'' in 2013, of which the genus name is an anagram. Two species that frequently build webs in and around human dwellings are now placed in this genus: the Agressive House Spider (''Eratigena agrestis'') (known as the hobo spider in the United States), native to Europe and Central Asia and introduced to North America, and the giant house spider (''Eratigena atrica''), native to Europe and also introduced into North America. Description They are medium to large spiders. Two symmetrical dark bands are present dorsally on the carapace, which can be serrated or reduced, usually to three or four conspicuous triangles. They also have plumose hairs on the carapace, legs, and opisthosoma. Their rows of eyes are only slightly curved in either direction.

Malthonica
''Malthonica'' is a genus of funnel weavers first described by Eugène Simon in 1898. Many of its species were transferred to ''Aterigena'' and ''Tegenaria ''Tegenaria'' is a genus of fast-running funnel weavers that occupy much of the Northern Hemisphere except for Japan and Indonesia. It was first described by Pierre André Latreille in 1804, though many of its species have been moved elsewhere. ...'' in 2010.

Agelenidae
The Agelenidae are a large family of spiders in the suborder Araneomorphae. Well-known examples include the common "grass spiders" of the genus ''Agelenopsis''. Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (''Eratigena agrestis'') may be medically significant, and some evidence suggests it might cause necrotic lesions, but the matter remains subject to debate. The most widely accepted common name for members of the family is funnel weaver. Description The body length of the smallest Agelenidae spiders are about , excluding the legs, while the larger species grow to long. Some exceptionally large species, such as ''Eratigena atrica'', may reach in total leg span. Agelenids have eight eyes in two horizontal rows of four. Their cephalothorax, cephalothoraces narrow somewhat towards the front where the eyes are. Their abdomens are more or less oval, usually patterned with two rows of lines and spots. Some species have longitudinal lines on the dors ... [...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 ...

Tegenaria
''Tegenaria'' is a genus of fast-running funnel weavers that occupy much of the Northern Hemisphere except for Japan and Indonesia. It was first described by Pierre André Latreille in 1804, though many of its species have been moved elsewhere. The majority of these were moved to '' Eratigena'', including the giant house spider (''Eratigena atrica'') and the hobo spider (''Eratigena agrestis''). They can be difficult to identify because they resemble wolf spiders and other funnel-web spiders in their area, unless found in an area where they do not occur naturally. They live on sheet webs, usually stretching across the corner between two walls. They have eight eyes in two straight or almost straight rows. Size varies from one species to another, but the body length of adults can range from to , not including the legs. The cardinal spider is the largest funnel weaver, with females that can grow up to long. Species it contains 129 species: *'' T. abchasica'' Charitonov, 194 ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...
