Ariston is a genus of cribellate orb-weavers first described by Octavius Pickard-Cambridge in 1896. [2]
As of April 2019 [update] it contains five species: [1]
Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
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 600 species in over 50 genera worldwide.
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.
Pachomius is a genus of jumping spiders that was first described by George and Elizabeth Peckham in 1896. Uspachia was merged into genus Romitia in 2007, and all nine species were merged into Pachomius in 2015. The name is derived from Pachomius, the founder of cenobitic monasticism.
Mallos is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by O. Pickard-Cambridge in 1902. Among the genus, Mallos gregalis is known to be a social spider species, living in groups and signaling each other by vibrating their web.
Anyphaena is a genus of anyphaenid sac spiders first described by Carl Jakob Sundevall in 1833.
Glenognatha is a genus of long-jawed orb-weavers that was first described by Eugène Louis Simon in 1887. It was considerably revised in 2016.
Ctenus is a genus of wandering spiders first described by Charles Athanase Walckenaer in 1805. It is widely distributed, from South America through Africa to East Asia. Little is known about the toxic potential of the genus Ctenus; however, Ctenus medius has been shown to share some toxic properties with Phoneutria nigriventer, such as proteolytic, hyaluronidase and phospholipase activities, in addition to producing hyperalgesia and edema. The venom of C. medius also interferes with the complement system in concentrations in which the venom of P. nigriventer is inactive, indicating that some species in the genus may have a medically significant venom. The venom of C. medius interferes with the complement component 3 (C3) of the complement system; it affects the central factor of the cascades of the complement, and interferes with the lytic activity of this system, which causes stronger activation and consumption of the complement components. Unlike C. medius, the venom of P. nigriventer does not interfere with lytic activity.
Macrophyes is a genus of anyphaenid sac spiders first described by O. Pickard-Cambridge in 1893.
Chrysometa is a genus of long-jawed orb-weavers that was first described by Eugène Louis Simon in 1894. It is a senior synonym of Capichameta.
Conifaber is a genus of spiders in the family Uloboridae. It was first described in 1982 by Opell. As of 2017, it contains 4 species, all from South America:
Siratoba is a genus of spiders in the family Uloboridae. It was first described in 1979 by Opell. As of 2017, it contains 2 species. The two species are Siratoba referens and Siratoba reticens. Siratoba referens were discovered in 1964 at the Dragoon Mountains, AZ, USA, and Siratoba reticins were discovered in 1942 at San Luis Potosí, Mexico.
Lehtineniana is a genus of South Pacific cribellate orb-weavers first described by Danniella Sherwood in 2022.
