Pselliopus is a common genus of assassin bug family (Reduviidae), in the subfamily Harpactorinae. The genus is restricted to the New World, with 22 species described. Some species, such as Pselliopus barberi, are conspicuous because of their bright coloring and relatively large size. Some species of the genus are of interest as potential biological pest control agents.
