The group is represented by five species in the eastern Pacific (Bussing 1990), 13 in the western North Atlantic ( Boehlke & Robins 1968; Colin, 2002) and two in the western South Atlantic: Elacatinus figaro Sazima et al. from the Brazilian coast (Sazima et al. 1996) and Elacatinus randalli ( Boehlke & Robins) from Fernando de Noronha Archipelago (Sazima & Moura, 2000). During recent field trips to Trindade Island, lying some 1160 km off the eastern Brazilian coast, we collected a third western south Atlantic species of the genus, which is described herein as new.
