Allagelena Bistriata
''Allagelena'' is a genus of Asia Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area ...n funnel weavers first described by Z. S. Zhang, Ming-Sheng Zhu & D. X. Song in 2006. Taxonomy The genus was created in 2006, initially for four Chinese species previously placed in '' Agelena''. The name ''Allagelena'' is derived from ''allo-'', different, and the genus name ''Agelena'', so meaning "different from ''Agelena''", specifically in male and female sexual characters. Three further species were later transferred to this genus. Species it contains nine species: *'' Allagelena bifida'' (Wang, 1997) – China *'' Allagelena bistriata'' (Grube, 1861) – Russia (Far East), China *'' Allagelena difficilis'' (Fox, 1936) – China, Korea *'' Allagelena donggukensis'' (Kim, 1996) – Korea, J ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
