Ocrepeira is a genus of orb-weaver spiders first described by George Marx in 1883. [2]
As of April 2019 [update] it contains sixty-seven species: [1]
Lyssomanes is a spider genus of the family Salticidae, ranging from South and Central America, up to the southern United States.
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.
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.
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.
Mangora is a genus of orb-weaver spiders first described by O. Pickard-Cambridge in 1889.
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.
Eustala is a genus of orb-weaver spiders first described by Eugène Simon in 1895.
Metazygia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904. They physically resemble members of Nuctenea, but they do not have fine setae on the carapace.
Wagneriana is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904.
Thymoites is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
Alpaida is a genus of South American orb-weaver spiders first described by Octavius Pickard-Cambridge in 1889.
