Cyclosa, also called trashline orbweavers, is a genus of orb-weaver spiders first described by Anton Menge in 1866. Widely distributed worldwide, spiders of the genus Cyclosa build relatively small orb webs with a web decoration. The web decoration in Cyclosa spiders is often linear and includes prey remains and other debris, which probably serve to camouflage the spider. The name "Cyclosa" comes from Greek 'to move in a circle', referring to how it spins its web.
Neoscona, known as spotted orb-weavers and barn spiders, is a genus of orb-weaver spiders (Araneidae) first described by Eugène Simon in 1895 to separate these from other araneids in the now obsolete genus Epeira. The name Neoscona was derived from the Greek νέω, meaning "spin", and σχοῐνος, meaning "reed" They have a mostly pantropical distribution and one species, Neoscona adianta, has a palearctic distribution. As of April 2019 there are eight species that can be found in the United States and Canada:
Theridion is a genus of tangle-web spiders with almost 600 described species around the world. Notable species are the Hawaiian happy face spider (T. grallator), named for the iconic symbol on its abdomen, and T. nigroannulatum, one of few spider species that lives in social groups, attacking prey en masse to overwhelm them as a team.
Chrysso is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1882.
Enoplognatha is a genus of comb-footed spiders that was first described by P. Pavesi in 1880. They have both a large colulus and a subspherical abdomen. Males usually have enlarged chelicerae. It is considered a senior synonym of Symopagia.
Pardosa is a large genus of wolf spiders, with more than 500 described species that are found in all regions of the world.
Olios is the largest genus of huntsman spiders, containing 177 species. They are found throughout the world, with most species occurring in hot countries. The genus was first described by Charles Athanase Walckenaer in 1837.
Cyrtarachne is a genus of orb-weaver spiders first described by Tamerlan Thorell in 1868.
Larinia is a genus of orb-weaver spiders first described by Eugène Simon in 1874.
Oxyopes is a genus of lynx spiders found worldwide. It includes arounds 300 species and is classified under the lynx spider family Oxyopidae. Like other lynx spiders, they are easily recognizable by the six larger eyes arranged hexagonally on top of the head (prosoma), with the remaining smaller two eyes in front. They are also characterized by long spine-like bristles (setae) on their legs. They are ambush predators, actively hunting prey by sight. Though they produce and use silk, they do not build webs to capture prey.
Eriovixia is a genus of orb-weaver spiders first described by Allan Frost Archer in 1951.
