Sphecozone is a genus of sheet weavers that was first described by Octavius Pickard-Cambridge in 1871. [5]
As of May 2019 [update] it contains thirty-four species, found in South America, the United States, and on the Trinidad: [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 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.
Sicarius is a genus of recluse spiders that is potentially medically significant to humans. It is one of three genera in its family, all venomous spiders known for a bite that can induce loxoscelism. They live in deserts and arid regions of the Southern Hemisphere, and females use a mixture of sand and silk when producing egg sacs. Most are native to South America, with the exception of Central America's S. rugosus, known primarily for its self-burying behavior.
Micrathena, known as spiny orbweavers, is a genus of orb-weaver spiders first described by Carl Jakob Sundevall in 1833. Micrathena contains more than a hundred species, most of them Neotropical woodland-dwelling species. The name is derived from the Greek "micro", meaning "small", and the goddess Athena.
Chrysso is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1882.
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.
Agyneta is a genus of dwarf spiders that was first described by J. E. Hull in 1911.
Laminacauda is a genus of dwarf spiders that was first described by Alfred Frank Millidge in 1985.
Linyphia is a genus of dwarf spiders that was first described by Pierre André Latreille in 1804. The name is Greek, and means "thread-weaver" or "linen maker".
Phoroncidia is a genus of comb-footed spiders that was first described by J. O. Westwood in 1835.
Parawixia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904. Most species are found in the Neotropics but one species, Parawixia dehaani, is found in Australasia and tropical Asia as far west as India.
Wagneriana is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904.
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.
Psilocymbium is a genus of South American sheet weavers that was first described by Alfred Frank Millidge in 1991.
Tutaibo is a genus of sheet weavers that was first described by Ralph Vary Chamberlin in 1916.
Arachosia is a genus of anyphaenid sac spiders that was first described by Octavius Pickard-Cambridge in 1882.
