Araneomorphae genera

Latrodectus is a broadly distributed genus of spiders informally called the widow spiders, with several species that are commonly known as the true widows. This group is composed of those often called black widow spiders, brown widow spiders, and similar spiders.

Tegenaria is a genus of fast-running funnel weavers that occupies much of the Northern Hemisphere except for Japan and Indonesia. It was first described by Pierre André Latreille in 1804, though many of its species have been moved elsewhere. The majority of these were moved to Eratigena, including the giant house spider (Eratigena atrica) and the hobo spider (Eratigena agrestis).

Nephila is a genus of araneomorph spiders noted for the impressive webs they weave. Nephila consists of numerous species found in warmer regions around the world, although some species formerly included in the genus have been moved to Trichonephila. They are commonly called golden silk orb-weavers, golden orb-weavers, giant wood spiders, or banana spiders.

Dolomedes is a genus of large spiders of the family Dolomedidae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all Dolomedes species are semiaquatic, with the exception of the tree-dwelling D. albineus of the southeastern United States. Many species have a striking pale stripe down each side of the body.

Pardosa is a large genus of wolf spiders, commonly known as the thin-legged wolf spiders. It was first described by C. L. Koch, in 1847, with more than 500 described species that are found in most regions of the world.

Eresus, also called ladybird spiders, is a genus of velvet spiders (family Eresidae) that was first described by Charles Athanase Walckenaer in 1805. Members of the genus formerly called Eresus cinnaberinus or Eresus niger are now placed in one of three species: Eresus kollari, Eresus sandaliatus and Eresus moravicus. A new species Eresus urus (named after the ancient Mesopotamian city of Ur), was discovered in southern Iraq in March 2025.

Cyrtophora, the tent-web spiders, is a genus of orb-weaver spiders first described by Eugène Simon in 1895. Although they are in the "orb weaver" family, they do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about long. Some members, including Cyrtophora cicatrosa, exhibit the ability to change colour rapidly.

Hypochilus is a genus of North American lampshade spiders that was first described by George Marx in 1888.

Theridion is a genus of tangle-web spiders with a worldwide distribution. 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.

Arkys, also known as triangular spider or ambush spider, is a genus of Australian araneomorph spiders in the family Arkyidae, first described by Charles Athanase Walckenaer in 1837. They are often small, with a triangular shaped abdomen, and are found in Australia and some of its surrounding islands. They don't build webs, but can often be found on leaves and tips of flower heads. Their egg sacs are pinkish-orange and spherical, and are made late in the summer.

Homalonychus is a genus of araneomorph spiders, and is the only genus in the family Homalonychidae. It was first described by George Marx in 1891. Its two described species are found in the southern United States and Mexico: H. theologus is mostly found west of the Colorado River, while H. selenopoides is mostly found to the east, with some populations in Death Valley and near Mercury, Nevada.

thumb|C. getazi with female katydid prey (Tettigoniidae sp.), Panama Cupiennius, known by the common name bromeliad spiders or as the often confused name banana spiders, is a genus of araneomorph spiders in the family Trechaleidae, named by Eugène Simon in 1891. They are found from Mexico to northwestern South America, and on some Caribbean islands. Unlike the dangerously venomous Phoneutria, bites from these spiders typically have only minor effects on humans, and have been compared to a bee sting.
