Alistra is a genus of dwarf sheet spiders that was first described by Tamerlan Thorell in 1894. [4]
As of May 2019 [update] it contains twenty-one species: [1]
Corinnidae is a family of araneomorph spiders, sometimes called corinnid sac spiders. The family, like other "clubionoid" families, has a confusing taxonomic history. Once it was a part of the large catch-all taxon Clubionidae, now very much smaller. The original members of the family are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks.
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.
Argyrodes, also called dewdrop spiders, is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1864. They occur worldwide, and are best known for their kleptoparasitism. They can spin their own webs, but tend to invade and reside in their hosts' webs. This relationship can be commensal or even mutual if the dewdrop spider feeds on small trapped insects that are not eaten by the host. Some species can even prey upon the host.
Clubiona is a genus of sac spiders that was first described by Pierre André Latreille in 1804.
Tetragnatha is a genus of long-jawed orb-weavers found all over the world. It was first described by Pierre André Latreille in 1804, and it contains hundreds of species. Most occur in the tropics and subtropics, and many can run over water. They are commonly called stretch spiders in reference to their elongated body form and their ability to hide on blades of grass or similar elongated substrates by stretching their front legs forward and the others behind them. The name Tetragnatha is derived from Greek, tetra- a numerical prefix referring to four and gnatha meaning "jaw". Evolution to cursorial behavior occurred long ago in a few different species, the most studied being those found on the Hawaiian islands. One of the biggest and most common species is T. extensa, which has a holarctic distribution. It can be found near lakes, river banks or swamps. Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.
Psechrus is a genus of cribellate araneomorph spiders in the family Psechridae, and was first described by Tamerlan Thorell in 1878.
Hahnia is a genus of dwarf sheet spiders that was first described by C. L. Koch in 1841.
Belisana is a genus of cellar spiders that was first described by Tamerlan Thorell in 1898.
Kapanga is a genus of South Pacific dwarf sheet spiders that was first described by Raymond Robert Forster in 1970.
Scotospilus is a genus of dwarf sheet spiders that was first described by Eugène Simon in 1886.
Hamataliwa is a genus of lynx spiders that was first described by Eugen von Keyserling in 1887.
