Desidae is a family of spiders, some of which are known as intertidal spiders. The family is named for the genus Desis, members of which inhabit the intertidal zone. The family has been reevaluated in recent years and now includes inland genera and species as well, such as Badumna and Phryganoporus. In 2017, the family Amphinectidae was merged into Desidae and the family Toxopidae was separated from it. Those intertidal spiders that are truly marine commonly live in barnacle shells, which they seal up with silk; this allows them to maintain an air bubble during high tide. They emerge at night to feed on various small arthropods that live in the intertidal zone.
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 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.
Amaurobiidae is a family of three-clawed cribellate or ecribellate spiders found in crevices and hollows or under stones where they build retreats, and are often collected in pitfall traps. Unlidded burrows are sometimes quite obvious in crusty, loamy soil. They are difficult to distinguish from related spiders in other families, especially Agelenidae, Desidae and Amphinectidae. Their intra- and interfamilial relationships are contentious. According to the World Spider Catalog, 2023, the family Amaurobiidae includes 286 species in 50 genera.
Tanzania is a genus of jumping spiders that was first described by A. Ö. Koçak & M. Kemal in 2008. They are very small spiders, with body lengths ranging from 1.5 to 3 millimetres. Both sexes look alike, but the females are sometimes darker. It is related to the Euophrys and Talavera. Three new species discovered in Tanzania by Wesolowska and Russell-Smith in 2000, and given the genus name Lilliput are now included in the genus Tanzania.
Huttoniidae is a family of ecribellate araneomorph spiders containing a single genus, Huttonia, itself containing a single described species, Huttonia palpimanoides. It is known only from New Zealand.
Stiphidiidae, also called sheetweb spiders, is a family of araneomorph spiders first described in 1917. Most species are medium size and speckled brown with long legs. All members of this family occur in New Zealand and Australia except for Asmea. They build a horizontal sheet-like web under rocks, hence the name "sheetweb spiders".
Cyatholipidae is a family of spiders first described by Eugène Simon in 1894. Most live in moist montane forest, though several species, including Scharffia rossi, live in dry savannah regions. They occur in Africa, including Madagascar, New Zealand and Australia, and one species in Jamaica. Most members of this family hang beneath sheet webs. Fossil species occur in the Eocene aged Bitterfield and Baltic Ambers, suggesting a wider geographic distribution in the past.
Cycloctenidae is a family of spiders first described by Eugène Simon in 1898.
Spelungula is a monotypic genus of South Pacific large-clawed spiders containing the single species, Spelungula cavernicola, or the Nelson cave spider.
Platnickina is a genus of comb-footed spiders that was first described by A. Ö. Koçak & M. Kemal in 2008.
Daviesa is a genus of Australian tangled nest spiders first described by A. Ö. Koçak & M. Kemal in 2008. This genus is named in honour of New Zealand arachnologist Valerie Todd Davies. As of April 2019 it contains only two species.
Orumcekia is a genus of Asian funnel weavers first described by A. Ö. Koçak & M. Kemal in 2008.
Uzakia is a monotypic genus of South Pacific araneomorph spiders in the family Cycloctenidae containing the single species, Uzakia unica. and has only been found in New Zealand.
Wanda Wesołowska is a Polish zoologist known for her work with jumping spiders. She has described more species of jumping spider than any contemporary writer, and is second only to Eugène Simon in the history of arachnology. Originally a student of ornithology, she developed an interest in jumping spiders while still a student at the Siedlce University of Natural Sciences and Humanities in the 1970s.
Eskovina is a monotypic genus of Asian dwarf spiders containing the single species, Eskovina clava. It was first described by A. O. Kocak & M. Kemal in 2006, and has only been found in China, Korea, and Russia.
Juanfernandezia is a monotypic genus of South American dwarf spiders containing the single species, Juanfernandezia melanocephala. It was first described by A. Ö. Koçak & M. Kemal in 2008, and has only been found in Chile.
Locketina is a genus of Southeast Asian dwarf spiders that was first described by A. O. Kocak & M. Kemal in 2006. As of May 2019 it contains only three species, found in Indonesia and Malaysia: L. fissivulva, L. pusilla, and L. versa.
Seycellesa is a genus of spiders in the family Theridiidae. It consists of only its type species: Seycellesa braueri, which is endangered and endemic to the Seychelles.
Forstera is a monotypic genus of Australian araneomorph spiders in the family Cyatholipidae containing the single species, Forstera daviesae. It was first described by A. Ö. Koçak & M. Kemal in 2008, and has only been found in Australia.
