Neomaso is a genus of dwarf spiders that was first described by Raymond Robert Forster in 1970. [2]
As of May 2021 [update] it contains twenty-two species: [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.
Amaurobiidae is a family of three-clawed cribellate or ecribellate spiders found in crevices and hollows or under stones where they build retreats, and are often collected in pitfall traps. Unlidded burrows are sometimes quite obvious in crusty, loamy soil. They are difficult to distinguish from related spiders in other families, especially Agelenidae, Desidae and Amphinectidae. Their intra- and interfamilial relationships are contentious. According to the World Spider Catalog, 2019, the family Amaurobiidae includes about 275 species in 49 genera.
Nemesiidae, also known as funnel-web trapdoor spiders, is a family of mygalomorph spiders first described by Eugène Simon in 1889, and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae".
Orsolobidae is a six-eyed spider family with about 180 described species in thirty genera. It was first described by J. A. L. Cooke in 1965, and was raised to family status from "Dysderidae" in 1985.
Sanogasta is a genus of South American anyphaenid sac spiders first described by Cândido Firmino de Mello-Leitão in 1941.
Laminacauda is a genus of dwarf spiders that was first described by Alfred Frank Millidge in 1985.
Molinaranea is a genus of South American orb-weaver spiders first described by Cândido Firmino de Mello-Leitão in 1940.
Orsolobus is a genus of South American araneomorph spiders in the family Orsolobidae, and was first described by Eugène Louis Simon in 1893.
Dubiaranea is a genus of dwarf spiders that was first described by Cândido Firmino de Mello-Leitão in 1943.
Notholepthyphantes is a genus of South American dwarf spiders that was first described by Alfred Frank Millidge in 1985.
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.
Allende is a genus of South American long-jawed orb-weavers that was first described by F. Álvarez-Padilla in 2007.
