Evarcha is a genus of spiders in the family Salticidae with 85 species distributed across the world.
Heliophanus is a genus of the spider family Salticidae. Most of the almost 170 described species occur in Africa, with many others found in the Palearctic region from Europe to Japan.
Hyllus is a genus of the spider family Salticidae.
Menemerus is a genus of jumping spiders that was first described by Eugène Louis Simon in 1868. They are 4 to 10 millimetres long, flattened in shape, and very hairy, usually with brown and grayish hairs. Most species have white edges on the thorax. The abdomen is often oval, or sometimes elongated or rounded.
Mogrus is a genus of jumping spiders that was first described by Eugène Louis Simon in 1882.
Phlegra is a genus of jumping spiders that was first described by Eugène Louis Simon in 1876. The name is a reference to a mythical location in both Greek and Roman mythology.
Plexippus is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846. It is considered a senior synonym of Hissarinus and Apamamia.
Rhene is a spider genus of the family Salticidae.
Cheiracanthium, commonly called yellow sac spiders, is a genus of araneomorph spiders in the family Cheiracanthiidae, and was first described by Carl Ludwig Koch in 1839. They are usually pale in colour, and have an abdomen that can range from yellow to beige. Both sexes range in size from 5 to 10 millimetres. They are unique among common house spiders because their tarsi do not point either outward, like members of Tegenaria, or inward, like members of Araneus), making them easier to identify. The name is a reference to the backwardly directed process on the cymbium of the male palp. The species epithet is derived from the Greek Ancient Greek: χείρ, romanized: cheir, meaning "hand", and Acanthium, a genus of thorny-stemmed plants.
Drassodes is a genus of ground spiders that was first described by Niklas Westring in 1851. They are brown, gray, and red spiders that live under rocks or bark in mostly dry habitats, and are generally 3.8 to 11.6 millimetres long, but can reach up to 20 millimetres (0.79 in) in length.
Ozyptila is a genus of crab spiders that was first described by Eugène Louis Simon in 1864. It has been misspelled as "Oxyptila" in multiple accounts.
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:
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.
Micaria is a genus of ground spiders that was first described by Niklas Westring in 1851. They are 1.3 to 6.5 millimetres long.
Haplodrassus is a genus of ground spiders that was first described by R. V. Chamberlin in 1922. They range from 3 to 10 millimetres. H. signifer is the most widespread species, found across North America except for Alaska and northern Canada.
Trachyzelotes is a genus of ground spiders that was first described by H. Lohmander in 1944 as a subgenus of Zelotes, and was raised to genus status in 1967. It has a body length of 3 to 13 millimetres.
