Bifurcia is a genus of Asian dwarf spiders that was first described by Michael I. Saaristo, L. H. Tu & S. Q. Li in 2006. [2]
As of July 2021 [update] it contains nine species, all from China and far eastern Russia: [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.
Neriene is a genus of sheet weavers that was first described by John Blackwall in 1833.
Molestia is a genus of East Asian dwarf spiders that was first described by L. H. Tu, Michael I. Saaristo & S. Q. Li in 2006.
Semljicola is a genus of sheet weavers that was first described by Embrik Strand in 1906.
Tenuiphantes is a genus of sheet weavers that was first described by Michael I. Saaristo & A. V. Tanasevitch in 1996.
Agyneta is a genus of dwarf spiders that was first described by J. E. Hull in 1911.
Diphya is a genus of long-jawed orb-weavers that was first described by H. Nicolet in 1849. D. tanasevitchi and D. albulum were transferred from Lophomma in 2007.
Capsulia is a genus of East Asian dwarf spiders that was first described by Michael I. Saaristo, L. H. Tu & S. Q. Li in 2006. As of May 2019 it contains only two species, both found in China: C. laciniosa and C. tianmushana.
Gongylidioides is a genus of Asian dwarf spiders that was first described by R. Oi in 1960.
Obscuriphantes is a genus of dwarf spiders that was first described by Michael I. Saaristo & A. V. Tanasevitch in 2000.
Oreoneta is a genus of dwarf spiders that was first described by C. Chyzer & Władysław Kulczyński in 1894.
Silometopoides is a genus of sheet weavers that was first described by K. Y. Eskov in 1990.
Stemonyphantes is a genus of sheet weavers that was first described by Anton Menge in 1866.
Tanasevitchia is a genus of Asian sheet weavers that was first described by Y. M. Marusik & Michael I. Saaristo in 1999. As of May 2019 it contains only two species, both found in Russia: T. strandi and T. uralensis.
Tekellina is a genus of comb-footed spiders that was first described by Herbert Walter Levi in 1957.
Erigomicronus is a genus of sheet weavers erected by A. V. Tanasevitch in 2018 for two east Asian species. In the following week, B. K. Seo published the new genus Collis for three Korean species. Further investigation revealed that all five belonged to the same genus, and preferences was given to the one published mere days before the other.
