Ctenus
Tropical Wandering Spiders
Ctenus is a genus of wandering spiders in the family Ctenidae, first described by Walckenaer in 1805. It comprises approximately 155 species with a broad distribution spanning South America, Africa, and East Asia. Species in this genus are abundant in tropical rainforest leaf litter, where they serve as active predators and have become model organisms for studying predator ecology in ground-dwelling arthropod communities. Some species, particularly C. medius, possess venom with documented proteolytic, hyaluronidase, and phospholipase activities, with potential medical significance due to complement system interference.
