Anyphaena Tibet
''Anyphaena'' is a genus of Anyphaenidae, anyphaenid sac spiders first described by Carl Jakob Sundevall in 1833. They are yellow or brownish in coloration, with a concave carapace that narrows gradually towards the head. Species it contains eighty-five species in North America, Europe, Middle East and Southern and Eastern Asia: *''Anyphaena accentuata, A. accentuata'' (Walckenaer, 1802) – Europe to Central Asia, Iran *''Anyphaena alachua, A. alachua'' Platnick, 1974 – USA *''Anyphaena alamos, A. alamos'' Platnick & Lau, 1975 – Mexico *''Anyphaena alboirrorata, A. alboirrorata'' Simon, 1878 – Portugal, Spain, France *''Anyphaena andina, A. andina'' Chamberlin, 1916 – Peru *''Anyphaena aperta, A. aperta'' (Banks, 1921) – USA, Canada *''Anyphaena arbida, A. arbida'' Platnick, 1974 – USA *''Anyphaena autumna, A. autumna'' Platnick, 1974 – USA *''Anyphaena ayshides, A. ayshides'' Yaginuma, 1958 – Japan *''Anyphaena bermudensis, A. bermudensis'' Sierwald, 1988 – B ...

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] |
