Laminacauda is a genus of dwarf spiders that was first described by Alfred Frank Millidge in 1985. [2]
As of May 2021 [update] it contains forty species, found in Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Panama, Peru, and Uruguay: [1]
Anyphaenidae is a family of araneomorph spiders, sometimes called anyphaenid sac spiders. They are distinguished from the sac spiders of the family Clubionidae and other spiders by having the abdominal spiracle placed one third to one half of the way anterior to the spinnerets toward the epigastric furrow on the underside of the abdomen. In most spiders the spiracle is just anterior to the spinnerets. Like clubionids, anyphaenids have eight eyes arranged in two rows, conical anterior spinnerets and are wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. There are more than 500 species in over 50 genera worldwide.
Linyphiidae is a family of very small spiders comprising 4694 described species in 623 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 Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Because of the difficulty in identifying such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Theridion is a genus of tangle-web spiders with almost 600 described species around the world. Notable species are the Hawaiian happy face spider (T. grallator), named for the iconic symbol on its abdomen, and T. nigroannulatum, one of few spider species that lives in social groups, attacking prey en masse to overwhelm them as a team.
Metepeira is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1903. The name is derived from the Ancient Greek μετά and the obsolete genus name Epeira, denoting a genus similar to Epeira.
Camillina is a genus of ground spiders that was first described by Lucien Berland in 1919. They are very similar to sister genus Zelotes.
Sanogasta is a genus of South American anyphaenid sac spiders first described by Cândido Firmino de Mello-Leitão in 1941.
Ariadna is a genus of tube-dwelling spider.
Petrichus is a genus of South American running crab spiders that was first described by Eugène Louis Simon in 1886.
Asemostera is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1898. Originally placed with the family Agelenidae, it was moved to the family Linyphiidae in 1965.
Dubiaranea is a genus of dwarf spiders that was first described by Cândido Firmino de Mello-Leitão in 1943.
Neomaso is a genus of dwarf spiders that was first described by Raymond Robert Forster in 1970.
Notiohyphantes is a genus of dwarf spiders that was first described by Alfred Frank Millidge in 1985.
Sphecozone is a genus of sheet weavers that was first described by Octavius Pickard-Cambridge in 1871.
