Arcuphantes is a genus of dwarf spiders that was first described by Ralph Vary Chamberlin & Vaine Wilton Ivie in 1943. [2]
As of May 2021 [update] it contains fifty-seven species found in Asia (many in Japan and Korea) and North America: [1]
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; 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. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Savignia is a genus of sheet weavers that was first described by John Blackwall in 1833. The name honors the French naturalist Marie Jules César Savigny.
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.
Cicurina, also called the cave meshweaver, is a genus of dwarf sheet spiders that was first described by Anton Menge in 1871. Originally placed with the funnel weavers, it was moved to the Dictynidae in 1967, then to the Hahniidae in 2017. The name is from the Latin root "cucur-", meaning "to tame".
Cybaeus is a genus of araneomorph spiders in the family Cybaeidae, first described by Ludwig Carl Christian Koch in 1868. It is found in America, Europe, Japan, Korea and China. Females of different species are difficult to distinguish, especially in North America. Images of males that include pedipalps are the easiest to determine species.
Agyneta is a genus of dwarf spiders that was first described by J. E. Hull in 1911.
Lathys is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Eugène Simon in 1884. It is a replacement name for "Lethia" Menge, 1869 because that name was already in use as a synonym for a genus of moths.
Gongylidioides is a genus of Asian dwarf spiders that was first described by R. Oi in 1960.
Nippononeta is a genus of Asian dwarf spiders that was first described by K. Y. Eskov in 1992.
Paikiniana is a genus of Asian dwarf spiders that was first described by K. Y. Eskov in 1992.
Phrurolithus is a genus of araneomorph spiders first described by C. L. Koch in 1839. First placed with the Liocranidae, it was moved to the Corinnidae in 2002, then to the Phrurolithidae in 2014.
