Mermessus is a genus of spiders in the family Linyphiidae. It was first described in 1899 by O. Pickard-Cambridge. As of 2017 [update] , it contains 81 species. [1]
Mermessus comprises the following species: [1]
Linyphiidae is a family of very small spiders comprising 4694 described species in 623 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly known; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Theridion is a genus of tangle-web spiders with almost 600 described species around the world. 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.
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.
Walckenaeria is a genus of dwarf spiders that was first described by John Blackwall in 1833. It is a senior synonym of Paragonatium, as well as Wideria, Cornicularia, Prosopotheca, Tigellinus, and Trachynella.
Erigone is a genus of dwarf spiders that was first described by Jean Victoire Audouin in 1826. They are carnivorous, preying on small insects such as psylla and flies. One of the distinctive characters for this genus is the presence of teeth bordering the carapace.
Dictyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Carl Jakob Sundevall in 1833.
Agyneta is a genus of dwarf spiders that was first described by J. E. Hull in 1911.
Linyphia is a genus of dwarf spiders that was first described by Pierre André Latreille in 1804. The name is Greek, and means "thread-weaver" or "linen maker".
Ceratinopsis is a genus of dwarf spiders that was first described by James Henry Emerton in 1882.
Floricomus is a genus of North American dwarf spiders that was first described by C. R. Crosby & S. C. Bishop in 1925.
Grammonota is a genus of dwarf spiders that was first described by James Henry Emerton in 1882.
Thymoites is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
