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.
Stemmops is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1894.
Hylyphantes is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1884. It is distinct from related genera by a pair of spiral copulatory ducts in the female, which are matched by a turbinated embolus in the male. Both sexes are similar in appearance; the male has no modifications.

Phintella parva is a species of jumping spider in the genus Phintella that lives in China, Japan, Korea and Russia.The species was first described by Wanda Wesołowska in 1981 based on a holotype from North Korea. However, retrospectively; it was recognised that other examples of the spider had been previously collected and, at one time, a description published without a species name. The spider is small, between 3.5 and 4 mm long, and yellow. The abdomen has a striped pattern and the carapace has circular markings, but the most distinguishing difference between this species and other members of the genus are the sexual organs, particularly the short curved embolus on the male and long straight insemination ducts in the female.
