Theridiidae

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 around 3,000 species in 128 genera, and is the most common arthropod group found in human dwellings throughout the world.

Argyrodes, also called dewdrop spiders, is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1864. They occur worldwide, and are best known for their kleptoparasitism. They can spin their own webs, but tend to invade and reside in their hosts' webs. This relationship can be commensal or even mutual if the dewdrop spider feeds on small trapped insects that are not eaten by the host. Some species can even prey upon the host.

Theridion is a genus of tangle-web spiders with a worldwide distribution. Notable species are the Hawaiian happy face spider (T. grallator), named for the iconic symbol on its abdomen, and T. nigroannulatum, one of few spider species that lives in social groups, attacking prey en masse to overwhelm them as a team.

Anelosimus is a cosmopolitan genus of cobweb spiders (Theridiidae), currently containing 74 species. Anelosimus is a key group in the study of sociality and its evolution in spiders (Aviles 1997). It contains species spanning the spectrum from solitary to highly social (quasisocial), with eight quasisocial species, far more than any other spider genus. Among these is the South American social species Anelosimus eximius, among the best studied social spider species.

Thwaitesia is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1881. The genus is named after George Henry Kendrick Thwaites.

Enoplognatha is a genus of comb-footed spiders first described by P. Pavesi in 1880. They were characterized by both a large colulus and a subspherical abdomen, with males usually have enlarged chelicerae. It is considered a senior synonym of Symopagia.

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.

Dipoena is a genus of tangle-web spiders that was first described by Tamerlan Thorell in 1869.

Tomoxena is a genus of Asian comb-footed spiders (family Theridiidae) that was first described by Eugène Louis Simon in 1895. it contains three species, found in Asia: T. alearia, T. dives, and T. flavomaculata.

Rhomphaea is a genus of comb-footed spiders that was first described by Ludwig Carl Christian Koch in 1872.

Coscinida is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1895.

Phycosoma is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1880.

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.

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.

Tidarren is a genus of tangle-web spiders first described by Ralph Vary Chamberlin & Wilton Ivie in 1934.
