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.
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.
Anatolidion is a monotypic genus of comb-footed spiders containing the single species, Anatolidion gentile. It was first described by J. Wunderlich in 2008, and is found in Africa and Europe.
Phylloneta is a genus of comb-footed spiders formerly considered a sub-genus of Allotheridion, and raised to genus status in 2008. The type species was first described by Eugen von Keyserling in 1884 as Theridion pictipes. As of September 2019 it contains three species and two subspecies with a holarctic distribution: P. impressa, P. pictipes, P. sisyphia, P. s. foliifera, and P. s. torandae.
Achaeridion is a monotypic genus of comb-footed spiders containing the single species, Achaeridion conigerum. It was first described by J. Wunderlich in 2008, and is found in Europe.
Borneoridion is a monotypic genus of comb-footed spiders containing the single species, Borneoridion spinifer. It was first described by C. Deeleman & J. Wunderlich in 2011, and is found on Borneo.
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.
Canalidion is a monotypic genus of tangle-web spiders containing the single species, Canalidion montanum. The species was first described by James Emerton in 1882 under the name Theridion montanum. J. Wunderlich moved it to its own genus in 2018, because it had more teeth on the anterior margin of the cheliceral furrow, a basal depression of the cymbium, and an embolus positioned dorsally. It has a holarctic distribution.
Exalbidion is a genus of comb-footed spiders that was first described by J. Wunderlich in 1995.
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.
Heterotheridion is a monotypic genus of comb-footed spiders with a palearctic distribution, containing the single species, Heterotheridion nigrovariegatum. It was first described by J. Wunderlich in 2008.
Jamaitidion is a monotypic genus of comb-footed spiders containing the single species, Jamaitidion jamaicense. The genus was first described by J. Wunderlich in 1995, and is found on the Greater Antilles. The sole species of this genus was described by Herbert Walter Levi in 1959. It was originally placed in Theridion, but was moved to its own genus based on unique features of the epigynum.
Magnopholcomma is a monotypic genus of comb-footed spiders containing the single species, Magnopholcomma globulus. It was first described by J. Wunderlich in 2008, and is found in Queensland.
Montanidion is a monotypic genus of Malaysian comb-footed spiders containing the single species, Montanidion kuantanense. It was first described by J. Wunderlich in 2011, and is found in Malaysia. The structure of the male pedipalp indicates that it may be related to members of Tamanidion.
Ohlertidion is a genus of comb-footed spiders that was first described by J. Wunderlich in 2008. As of September 2019 it contains three species with a holarctic distribution, including Greenland: O. lundbecki, O. ohlerti, and O. thaleri. A 2019 genetic study proposed to synonymize this genus with Heterotheridion; however, the evidence was based predominantly on COI barcoding, which is a useful tool for separating species, but is less useful for determining higher taxa.
Paidiscura is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1950.
Ruborridion is a monotypic genus of Asian comb-footed spiders containing the single species, Ruborridion musivum. The species was first described under the name Theridion musivum in 1873. The genus was described by J. Wunderlich in 2011. They are found in India and in the mediterranean area
Sardinidion is a monotypic genus of comb-footed spiders containing the single species, Sardinidion blackwalli. It was first described by J. Wunderlich in 1995, and is found in Africa and Europe.
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.
