Beata is a genus of jumping spiders that was first described by George Peckham & Elizabeth Peckham in 1895.
Lyssomanes is a spider genus of the family Salticidae, ranging from South and Central America, up to the southern United States.
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.
Pachomius is a genus of jumping spiders that was first described by George and Elizabeth Peckham in 1896. Uspachia was merged into genus Romitia in 2007, and all nine species were merged into Pachomius in 2015. The name is derived from Pachomius, the founder of cenobitic monasticism.
Sidusa is a genus of jumping spiders that was first described by George and Elizabeth Peckham in 1895.
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.
The Dendryphantina are a subtribe of jumping spiders that occur mainly in the New World. The subtribe was first defined by Anton Menge in 1879 as Dendryphantidae. Females of the subtribe generally show paired spots on the abdomen, and the males often have enlarged chelicerae. Females in this subtribe typically have S-shaped epigynal openings.
Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.
Colonus is a genus of spiders in the jumping spider family, Salticidae. Colonus species are endemic to North and South America, ranging from New York to Argentina. All members of the genus have two pairs of bulbous spines on the ventral side of the first tibiae. The function of these spines is unknown. Colonus was declared a junior synonym of Thiodina by Eugène Simon in 1903, but this was reversed by Bustamante, Maddison, and Ruiz in 2015.
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.
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.
Eustala is a genus of orb-weaver spiders first described by Eugène Simon in 1895.
Hamataliwa is a genus of lynx spiders that was first described by Eugen von Keyserling in 1887.
