The family Dipluridae, known as curtain-web spiders are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (Atrax), used to be classified in this family but have now been moved to Atracidae.
The spider family Liphistiidae, recognized by Tamerlan Thorell in 1869, when broadly circumscribed to include two subfamilies, comprises 8 genera and about 100 species of medium-sized spiders from Southeast Asia, China, and Japan. They are among the most basal living spiders, belonging to the suborder Mesothelae. In Japan, the Kimura spider is well known. In 2022, it was proposed to re-accept the subfamily Heptathelinae as the family Heptathelidae. As of December 2023, this proposal was accepted by the World Spider Catalog. In this circumscription, the family Liphistiidae has only one genus, Liphistius.
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.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Scaffold web spiders or cave cobweb spiders (Nesticidae) are a family of araneomorph spiders closely allied with tangle-web spiders (Theridiidae). Like the Theridiidae, these spiders have a comb of serrated bristles on the hind tarsi that are used to pull silk bands from the spinnerets. Nesticidae contains 16 genera and about 300 species, many of which are associated with caves or overhangs. The genus Nesticus is the type for the family and is found throughout the world. The related Eidmannella has speciated considerably in Texas caves and includes some extremely localized species that are considered threatened. One species, Eidmannella pallida, is found in caves and under overhangs, but also in agricultural fields and other habitats away from such restricted areas. The genus Carpathonesticus is found in central Eurasia.
Salticus is a genus of the family Salticidae. Salticus is the type genus for the family Salticidae.
Archaeidae, also known as assassin spiders and pelican spiders, is a spider family with about ninety described species in five genera. It contains small spiders, ranging from 2 to 8 millimetres long, that prey exclusively on other spiders. They are unusual in that they have "necks", ranging from long and slender to short and thick. The name "pelican spider" refers to these elongated jaws and necks used to catch their prey. Living species of Archaeidae occur in South Africa, Madagascar and Australia, with the sister family Mecysmaucheniidae occurring in southern South America and New Zealand.
Rugathodes is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1950. It is closely related to members of Theridion and Wamba.
Spermophorides is a genus of cellar spiders that was first described by J. Wunderlich in 1992.
Canariphantes is a genus of dwarf spiders that was first described by J. Wunderlich in 1992. It might be a junior synonym of Lepthyphantes.
Parapelecopsis is a genus of dwarf spiders that was first described by J. Wunderlich in 1992. The spider is found in woodlands in leaf litter, pine needles, moss at ground level and lichen and moss on tree trunks.
Cameronidion is a monotypic genus of Malaysian comb-footed spiders containing the single species, Cameronidion punctatellum. It was first described by J. Wunderlich in 2011, and is found in Malaysia.
Dipoenata is a genus of comb-footed spiders that was first described by J. Wunderlich in 1988.
Grancanaridion is a monotypic genus of comb-footed spiders containing the single species, Grancanaridion grancanariense. It was first described by J. Wunderlich in 2011, and is found on the Canary Islands.
Macaridion is a monotypic genus of European comb-footed spiders containing the single species, Macaridion barreti. The genus was first described by J. Wunderlich in 1992, and it is found in Portugal and Spain. The sole species was first described under the name Theridion barreti, but it was elevated to its own genus in 1992.
Simitidion is a genus of comb-footed spiders that was first described by J. Wunderlich in 1992. As of June 2020 it contains three species, native to Africa, Asia and Europe, and introduced to Canada: S. agaricographum, S. lacuna, and S. simile.
Tamanidion is a monotypic genus of Asian comb-footed spiders containing the single species, Tamanidion multidenticuli. It was first described by J. Wunderlich in 2011, and is found in Malaysia.
Bassaniodes is a genus of crab spiders that was first described by Reginald Innes Pocock in 1903.
Liophrurillus is a monotypic genus of araneomorph spiders in the family Phrurolithidae, containing the single species, Liophrurillus flavitarsis. It was first described by J. Wunderlich in 1992 as a possible corinnid sac spider, and was moved to Phrurolithidae in 2014. It has only been found in Europe and North Africa.
Priscaleclercera is a genus of araneomorph spiders in the family Psilodercidae, containing seven species. The genus was first described by Jorge Wunderlich in 2017, and its fossils have been found in Burmese amber, while live specimens have been found in Indonesia (Sulawesi).
