Linyphiidae is a family of very small spiders comprising 4667 described species in 618 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly known; new genera and species are still being discovered throughout the world. The newest such genus is Yuelushannus from China, formally described in May 2020. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
