Anelosimus Exiguus
''Anelosimus'' is a cosmopolitan genus of cobweb spiders (Theridiidae), currently containing 74 species. ''Anelosimus'' is a key group in the study of sociality and its evolution in spiders (Aviles 1997). It contains species spanning the spectrum from solitary to highly social (quasisocial), with eight quasisocial species, far more than any other spider genus. Among these is the South American social species ''Anelosimus eximius'', among the best studied social spider species. The web of a colony of ''A. eximius'' can reach cover entire tree canopies and contain tens of thousands of individuals. Most of the highly social species live in lowland tropical forests, and all occur in the Americas. Other species, particularly those at higher altitudes in northern latitudes in the Americas and all non-American species appear to be solitary or sub-social. Social ''Anelosimus'' species are generally highly inbred and have female-biased sex ratios, with up to 10 females per male. The soci ...

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 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 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 fossil spider species '' Cenotextricella simoni'' was named in his ...

Anelosimus Buffoni
''Anelosimus buffoni'' is a species of tangle-web spiders in the Madagascar group of the genus ''Anelosimus''. It is known only from Périnet Special Reserve, Toamasina Province, Madagascar. Adults of the species have a total length of 4.1mm, and is physically similar to several other Madagascar group spiders, particularly '' A. andasibe'' and '' A. wallacei''. It is primarily diagnosed using genetics. The species is named for Georges-Louis Leclerc, Comte de Buffon. Specimens There are only two specimens of this spider in existing collections. Although multiple specimens were reported to have been collected, only two exist in collections; the rest were reported lost in transit when the co-discoverer, Ingi Agnarsson, brought his research materials from University of Puerto Rico to University of Vermont The University of Vermont (UVM), officially the University of Vermont and State Agricultural College, is a Public university, public Land-grant university, land-grant ...

Anelosimus Eidur
''Anelosimus eidur'' is a species of tangle-web spider found in Papua New Guinea. Its habitat is high elevation scrub forest, in Southern Highlands Province and Enga Province Enga is one of the provinces in Papua New Guinea (PNG). It is located in the north most region of the highlands of PNG, having been divided from the Western Highlands to become a separate province when the provinces were created at the time of in .... It has a total length of , with the females being larger than the males. It can be identified by its unique genitalia, particularly the spiraling embolus in the males. The web structure is similar to social and sub-social species, leading to its tentative identification as subsocial. The species is named Eiður Francis, the son of Ingi Agnarsson who first identified the species in 2012. References Theridiidae Spiders of Oceania Spiders described in 2012 {{Theridiidae-stub ...

Anelosimus Dude
''Anelosimus dude'' is a species of spider in the family Theridiidae. It is native to Tanzania, having only been found in the Udzungwa Scarp Forest ReserveIn the publication of the find, Agnarsson and Zhang (2006), this was described as "Uzungwa Scarp Forest Reserve" and Mazumbai Forest Reserve. It is closely related to '' Anelosimus biglebowski''. The name ''A. dude'' derives from "The Dude", a character in the 1998 film '' The Big Lebowski''. Biology ''Anelosimus dude'' ranges in size from 1.80mm to 2.10mm for male total length and from 1.85mm to 2.15mm for female total length. Coloration is generally grey, but varies greatly. ''A. dude'' may have a skewed sex ratio of approximately 2.6 females to 1 male.
