Long-jawed orb weavers or long jawed spiders (Tetragnathidae) are a family of araneomorph spiders first described by Anton Menge in 1866. They have elongated bodies, legs, and chelicerae, and build small orb webs with an open hub with few, wide-set radii and spirals with no signal line or retreat. Some species are often found in long vegetation near water.
Corythalia is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1850. The genus is distributed throughout most of the Western Hemisphere. Species of this genus are found in The Americas.
Metaphidippus is a genus of jumping spiders that was first described by Frederick Octavius Pickard-Cambridge in 1901. The name is combined from Ancient Greek μετά "after, beside" and the salticid genus Phidippus.
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.
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.
Gelanor is a genus of spiders in the family Mimetidae, found in Central and South America.
Corinna is a genus of corinnid sac spiders first described by Carl Ludwig Koch in 1841. They are found in Mexico and south to Brazil, and with selected species found in Africa.
Elaver is a genus of sac spiders first described by Octavius Pickard-Cambridge in 1898.
Trachelas is a genus of araneomorph spiders originally placed with the Trachelidae, and later moved to the Corinnidae.
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.
Hamataliwa is a genus of lynx spiders that was first described by Eugen von Keyserling in 1887.
Modisimus is a genus of cellar spiders that was first described by Eugène Louis Simon in 1893.
Faiditus is a genus of comb-footed spiders that was first described by Eugen von Keyserling in 1884.
