Exalbidion is a genus of comb-footed spiders that was first described by J. Wunderlich in 1995. [2]
As of May 2020 [update] it contains six species, found in the Caribbean and from Mexico to Brazil: [1]
In synonymy:
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.
Long-jawed orb weavers or long jawed spiders (Tetragnathidae) are a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water.
Achaearanea is a genus of comb-footed spiders that was first described by Embrik Strand in 1929.
Theridiosomatidae, commonly known as Ray Spiders, are a family of araneomorph spiders first described by Eugène Simon in 1881. The family includes 137 species divided between 20 genera. They are most recognizable for their construction of cone-shaped webs.
Theridiosoma is a genus of ray spiders that was first described by Octavius Pickard-Cambridge in 1879. They use their web as a high speed slingshot to actively hunt for prey.
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.
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.
Cryptachaea is a genus of spiders in the Theridiidae family.
Euryopis is a genus of comb-footed spiders that was first described by Anton Menge in 1868.
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.
Dipoena is a genus of tangle-web spiders that was first described by Tamerlan Thorell in 1869.
Ameridion is a genus of comb-footed spiders that was first described by J. Wunderlich in 1995. Species of this genus are found in Mexico, Central America, Northern South America and the West Indies.
Faiditus is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
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.
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.
Thymoites is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
