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.
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.
Drapetisca is a genus of dwarf spiders that was first described by Anton Menge in 1866. Females are 4 to 5 millimetres long, and males are 3 to 4 millimetres long. They are common on tree trunks from July to September, and they feed on insects and smaller spiders.

Epiceraticelus is a genus of North American dwarf spiders containing two species: Epiceraticelus fluvialis and Epiceraticelus mandyae. The first described species in the genus, E. fluvialis, was first described by C. R. Crosby & S. C. Bishop in 1931, and has only been found in the Midwestern and Eastern United States. The second species, E. mandyae, was described in 2019 by M. L. Draney et al. and occurs in the Southeastern United States from Eastern New Jersey south to Georgia and west to Louisiana. The male of E. mandyae has a curved proboscis that extends from below the eyes. Epiceraticelus mandyae was named after the late arachnologist, Amanda Howe, in honor of her contributions to the North American arachnology community.
