Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
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. However, 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, 2019, the family Amaurobiidae includes about 275 species in 49 genera.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
Tanzania is a genus of African 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.
Huttonia is a monotypic genus of ecribellate South Pacific araneomorph spiders in the Huttoniidae family containing the single species, Huttonia palpimanoides. Although only one species is described, there are still about twenty more undescribed species.
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.
The Nelson cave spider (Spelungula) is a monotypic genus of South Pacific large-clawed spiders containing the single species, Spelungula cavernicola. It was first described by Raymond Robert Forster, Norman I. Platnick, & Michael R. Gray in 1987, and has only been found in caves in the northwestern part of New Zealand's South Island.
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. 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. It was first described by A. Ö. Koçak & M. Kemal in 2008, and has only been found in New Zealand.
Hulua is a genus of South Pacific araneomorph spiders in the family Toxopidae, and was first described by Raymond Robert Forster & C. L. Wilton in 1973. Originally placed with the intertidal spiders, it was moved to the Toxopidae in 2017.
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.
