Ctenus
''Ctenus'' is a genus of Ctenidae, 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.
