Sycorax confusa sp. nov. is described from the Atlantic Forest of the state of Espírito Santo, Brazil. The new species has a paramere with a long bristle, a characteristic that had only been observed in Sycorax longispinosa Bravo, 2007 from the Brazilian Amazon; the new species can be differentiated from the last one because the middle acute internal projections of each paramere do not cross each other and because the anterior end of aedeagal apodeme is bulbous. A key to the species of Sycorax Haliday in Curtis, 1839 (males) from the Neotropical Region is provided.
