Cryptachaea is a genus of spiders in the Theridiidae (tangle web spider) family. [1]
Many species in this genus used to reside in Achaearanea , [1] which received a major revision in 2008 by Hajime Yoshida. [2] The genus was originally established as a subgenus of Theridion . [1] [2]
This is mostly a New World genus, with many species in South America. One species is cosmopolitan, one species occurs in the whole Palearctic, another only in China. [1] C. veruculata was introduced to Europe from New Zealand.
The genus name is a combination of Achaea, the old name of the genus Achaearanea, and Ancient Greek κρυπτός "hidden". The genus is called Iwama-himegumo zoku in Japanese. [2]
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.
Achaearanea is a genus of comb-footed spiders that was first described by Embrik Strand in 1929.
Episinus is a genus of comb-footed spiders that was first described by Pierre André Latreille in 1809.
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.
Stemmops is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1894.
Chrosiothes is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1894. It is considered a senior synonym of Theridiotis.
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. 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.
Dipoena is a genus of tangle-web spiders that was first described by Tamerlan Thorell in 1869.
Eustala is a genus of orb-weaver spiders first described by Eugène Simon in 1895.
Echinotheridion is a genus of comb-footed spiders that was first described by Herbert Walter Levi in 1963.
Exalbidion is a genus of comb-footed spiders that was first described by J. Wunderlich in 1995.
Faiditus is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
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.
Neopisinus is a genus of comb-footed spiders that was first described by M. A. L. Marques, E. H. Buckup & E. N. L. Rodrigues in 2011.
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.
