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.
Styposis is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1894. It is a senior synonym of Cyatholipulus.
Hetschkia is a monotypic genus of Brazilian comb-footed spiders containing the single species, Hetschkia gracilis. It was first described by Eugen von Keyserling in 1886, and is found in Brazil.
Wirada is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1886.
The spider genus Spintharus occurs from the northeastern United States to Brazil. Nicholas Marcellus Hentz circumscribed the genus in 1850, initially as a monospecific genus containing his newly described species S. flavidus.
Thwaitesia is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1881.
Stemmops is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1894.
Theridula is a genus of cobweb spiders, found in many parts of the world. Species vary in size from 1 to 3.5 mm in length.
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.
Theridula emertoni is a species of tangle web spider commonly found in the United States and Canada. Prior to its formal description in 1954, specimens of T. emertoni were often classified as T. opulenta, a species with whom its range overlaps. The species can be reliably distinguished from T. opulenta by the epigyne in females or by the pedipalp in males.
Platnickina is a genus of comb-footed spiders that was first described by A. Ö. Koçak & M. Kemal in 2008.
Lasaeola is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1881. The type species was described under the name Pachydactylus pronus, but was renamed Lasaeola prona when it was discovered that the name "Pachydactylus" was preoccupied. Both this genus and Deliana were removed from the synonymy of Dipoena in 1988, but many of these species require more study before their placement is certain.
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.
Hentziectypus is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946. Originally placed with Theridion, it was moved to Achaearanea in 1955, and to its own genus in 2008. These spiders most resemble members of Cryptachaea, but are distinguished by a median apophysis that is broadly attached to the tegulum. Spiders of Parasteatoda have a median apophysis attached to the embolus, while those of Achaearanea have a hooked paracymbium on the pedipalps of males.
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.
Paidiscura is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1950.
Pholcomma is a genus of comb-footed spiders that was first described by Tamerlan Thorell in 1869.
Tekellina is a genus of comb-footed spiders that was first described by Herbert Walter Levi in 1957.
Thymoites is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
Yaginumena is a genus of comb-footed spiders that was first described by H. Yoshida in 2002. As of June 2020 it contains three species, found in Asia and Turkey: Y. castrata, Y. maculosa, and Y. mutilata.
