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.
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
Theridiosoma is a genus of ray spiders that was first described by Octavius Pickard-Cambridge in 1879. They use their web as a high speed slingshot to actively hunt for prey.
Tetrablemmidae, sometimes called armored spiders, is a family of tropical araneomorph spiders first described by Octavius Pickard-Cambridge in 1873. It contains 126 described species in 29 genera from southeast Asia, with a few that occur in Africa and Central and South America. Pacullidae was incorporated into this family in 1981, but was later restored as a separate family in a 2016 phylogenetic study.
Stenochilidae is a family of southeast Asian araneomorph spiders that produce ecribellate silk. First described by Tamerlan Thorell in 1873, it now contains twelve described species in two genera.
Pacullidae is a family of araneomorph spiders first described by Eugène Simon in 1894. It was merged into Tetrablemmidae in 1958, then raised back to family status after a large phylogenetic study in 2017.
Nesticella is a genus of spiders of the family Nesticidae. Most of its species are found in Asia—from Russia to Japan, down to Indonesia and several other islands, including New Guinea—though some species from Africa and South-America are also known. It includes a blind spider, Nesticella marapu.
Pritha is a genus of crevice weavers that was first described by Pekka T. Lehtinen in 1967.
Phrynarachne is a genus of crab spiders first described by Tamerlan Thorell in 1869.
Brignoliella is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by W. A. Shear in 1978.
Tetrablemma medioculatum is a species of spider of the genus Tetrablemma. The nominate subspecies is endemic to Sri Lanka. Two other subspecies can be found, both of which are endemic to India.
Ablemma is a genus of araneomorph spiders in the family Tetrablemmidae that was first described by Carl Friedrich Roewer in 1963.
Asianopis is a genus of Asian net-casting spiders first described by Y. J. Lin, L. Shao and A. Hänggi in 2020.
Bowie is a genus of Ctenidae that was described by Peter Jäger in 2022. The genus was named after the English singer-songwriter and actor David Bowie and currently encompasses 107 species, 55 of which were named after elements from David Bowie's musical catalogue.
