'''''Ctenus''''' is a [genus](/source/genus) of [wandering spiders](/source/Ctenidae) first described by [Charles Athanase Walckenaer](/source/Charles_Athanase_Walckenaer) in 1805.<ref name=Walc1805 /> It is widely distributed, from South America through Africa to East Asia.<ref name=wsc />

==Venom==
Little is known about the toxic potential of the genus ''Ctenus''; however, ''[Ctenus medius](/source/Ctenus_medius)'' has been shown to share some toxic properties with ''[Phoneutria nigriventer](/source/Phoneutria_nigriventer)'', such as [proteolytic](/source/proteolytic), [hyaluronidase](/source/hyaluronidase) and [phospholipase](/source/phospholipase) activities, in addition to producing [hyperalgesia](/source/hyperalgesia) and [edema](/source/edema).<ref name=ento9 />

The venom of ''C. medius'' also interferes with the [complement system](/source/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.<ref name=ento9 /> The venom of ''C. medius'' interferes with the [complement component 3](/source/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.<ref name=ento9 />

==Species==
{{as of|2025|10}}, this genus includes 155 species.<ref name="wsc" />
