Mimetus is a genus of pirate spiders in the family Mimetidae. They are found worldwide.
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.
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.
Wulfila is a genus of ghost spiders first described by O. Pickard-Cambridge in 1895. They are easily recognized by their pale white elongated legs.
