Faiditus is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884. [3]
As of May 2020 [update] it contains fifty-nine species, all found in the Americas except for F. xiphias, found in Asia: [1]
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.
Micrathena, known as spiny orbweavers, is a genus of orb-weaver spiders first described by Carl Jakob Sundevall in 1833. Micrathena contains more than a hundred species, most of them Neotropical woodland-dwelling species. The name is derived from the Greek "micro", meaning "small", and the goddess Athena.
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.
Chrysso is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1882.
Cryptachaea is a genus of spiders in the Theridiidae family.
Metepeira is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1903. The name is derived from the Ancient Greek μετά and the obsolete genus name Epeira, denoting a genus similar to Epeira.
Mangora is a genus of orb-weaver spiders first described by O. Pickard-Cambridge in 1889.
Dipoena is a genus of tangle-web spiders that was first described by Tamerlan Thorell in 1869.
Parawixia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904. Most species are found in the Neotropics but one species, Parawixia dehaani, is found in Australasia and tropical Asia as far west as India.
Eustala is a genus of orb-weaver spiders first described by Eugène Simon in 1895.
Metazygia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904. They physically resemble members of Nuctenea, but they do not have fine setae on the carapace.
Neospintharus is a genus of comb-footed spiders that was first described by H. Exline in 1950. It was synonymized with Argyrodes in 1962, but revalidated in 2004.
Rhomphaea is a genus of comb-footed spiders that was first described by Ludwig Carl Christian Koch in 1872.
Thymoites is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
Alpaida is a genus of South American orb-weaver spiders first described by Octavius Pickard-Cambridge in 1889.
