Gaius Villosus
''Gaius villosus'' is a species of spider in the family Idiopidae (armored trapdoor spiders) found in Western Australia in a variety of different habitats. Originally described in 1914 as ''Gaius villosus'' by William Joseph Rainbow, in 1957 it was transferred to ''Anidiops'' by Barbara Main (a genus no longer recognized). In 2017, it was returned to ''Gaius Gaius, sometimes spelled ''Gajus'', Kaius, Cajus, Caius, was a common Latin praenomen; see Gaius (praenomen).

William Joseph Rainbow
William Joseph Rainbow (1856–1919) was an entomologist and arachnologist whose work includes the first catalogue of Australian spiders. Life Rainbow was born in 1856 in Yorkshire, England. His father was a Warrant Officer in the Royal Marines, so his education was in a number of port towns and in Edinburgh. He emigrated to New Zealand in 1873, where he wrote for John Ballance's ''Wanganui Herald''. Rainbow's early interest in natural history was assisted by Ballance, who prompted him to build a career in the field. In 1883 he moved to Sydney, Australia and married Arriette Dainty. He continued to contribute to newspapers and journals, including ''The Sydney Morning Herald'', ''Daily Telegraph'', and Evening News, then worked for the Government Printing Office until 1895; in this year he took up a position at the Australian Museum as an entomologist. Rainbow was a founder of the Naturalists' Society of New South Wales, serving as its president. He was a member of the Linnea ...

Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Idiopidae
Idiopidae, also known as armored trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889. They have a large body similar to tarantulas. Description In some species the males have a spur on their legs, which they will show if provoked.Find-a-spider Guide Idiopidae build burrows, and some species close these with a door. The about 2 cm long ''Prothemenops siamensis'' from Thailand builds its retreat in a streamside vertical earth bank in lower montane rain forest. Each burrow had two or three entrances that lead into a main tube. Its lateral posterior spinnerets are elongated. The oldest known idiopid, Number 16, died at the age of 43 years. Genera As of 2019, the World Spider Catalog accepts the following genera: *'' Arbanitis'' L. Koch, 1874 — Australia *'' Blakistonia'' Hogg, 1902 — Australia *'' Bungulla'' Rix, Main, Raven & Harvey, 2017 — Australia *'' Cantuaria'' Hogg, 1902 — New Zealand, Australia *'' Cataxia'' Rainbo ...

Gaius (spider)
''Gaius'' is a genus of large mygalomorph spiders in the family Idiopidae. Erected in 1914 by William Joseph Rainbow, for much of its history the genus contained only one species, ''Gaius villosus''. More species were added in 2018. All are endemic to Western Australia. Description Species of ''Gaius'' are large spiders, usually dark brown or black. Females have a body length of around , males around . The carapace has a dense fringe of hairs (setae) along the sides. The abdomen is oval, densely covered with hairs. Males have pedipalps with a retrolateral tibial apophysis (RTA), which in most species is large and long. Females have a pair of simple, widely spaced spermathecae. Taxonomy The genus ''Gaius'' was erected by William Joseph Rainbow in 1914 for his new species ''Gaius villosus''. In 1957, Barbara York Main transferred ''G. villosus'' (then still the only species of ''Gaius'') to the genus ''Anidiops'', noting the inadequacy of many characters used in mygalomorph ta ...

Number 16 (spider)
Number 16 (c. 1973 – 2016), also known as #16, was a wild female trapdoor spider ('' Gaius villosus,'' family Idiopidae) that lived in North Bungulla Reserve near Tammin, Western Australia. She died in 2016, at an estimated age of 43 years, and is the longest-lived spider recorded to date. Number 16 did not die of old age, but was most likely killed by a parasitic wasp sting. Long-term monitoring Number 16 was studied in the wild by arachnologist Barbara York Main from March 1974 until 2016. She was part of the first cohort of dispersing spiderlings to establish a burrow at the study site, and her burrow was the 16th to be marked with a peg. By 1978, Main had tagged 101 burrows at the study site, within a few metres of each other. Number 16 spent her entire life in the same burrow, which is typical for her species. For over 40 years, her status was monitored by Main and her collaborators either six-monthly or annually. As Number 16 became older, the researchers developed a trad ...
