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.
Megalepthyphantes is a genus of dwarf spiders that was first described by J. Wunderlich in 1994.
Abiskoa is a monotypic genus of dwarf spiders containing the single species, Abiskoa abiskoensis. It was first described by Michael I. Saaristo & A. V. Tanasevitch in 2000, and has only been found in Europe, East Asia, and China.

Indophantes is a genus of Asian dwarf spiders that was first described by Michael I. Saaristo & A. V. Tanasevitch in 2003.
Mesasigone is a monotypic genus of Asian dwarf spiders containing the single species, Mesasigone mira. It was first described by A. V. Tanasevitch in 1989, and has only been found in China, Iran, Kazakhstan, and Russia.

Obscuriphantes is a genus of dwarf spiders that was first described by Michael I. Saaristo & A. V. Tanasevitch in 2000.
Sachaliphantes is a monotypic genus of Asian sheet weavers containing the single species, Sachaliphantes sachalinensis. It was first described by Michael I. Saaristo & A. V. Tanasevitch in 2004, and has only been found in Japan, Korea, China, and Russia.
Taibainus is a monotypic genus of East Asian sheet weavers containing the single species, Taibainus shanensis. It was first described by A. V. Tanasevitch in 2006, and has only been found in China.
Taibaishanus is a monotypic genus of East Asian sheet weavers containing the single species, Taibaishanus elegans. It was first described by A. V. Tanasevitch in 2006, and has only been found in China.
Tchatkalophantes is a genus of sheet weavers that was first described by A. V. Tanasevitch in 2001.
Parbatthorax is a small genus of Asian sheet weavers first described by A. V. Tanasevitch in 2019. As of April 2022 it contains only two species: P. proiectus and P. unicornis. Its appearance resembles members of Gongylidioides and Glebala, but it can be distinguished by the unique shape of its carapace and a highly modified palpal tibia and paracymbium. The genus name is a combination of the Parbat District, where the first specimen was found, and the "thorax", whose unique shape is one of its distinguishing factors.
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.
Vietnagone is a small genus of Asian sheet weavers native to southeastern Tibet and northern Vietnam. It was erected by A. V. Tanasevitch in 2019 for one newly described species and one transferred from Gongylidium. They are relatively small spiders, ranging from 1.5 to 1.78 millimetres long. The name is a combination of "Vietnam" and the genus Erigone, and as of April 2022 it contains only two species: V. rugulosa and V. silvatica.
