The sea urchin Centrostephanus longispinus rubicingulus was rediscovered on the continental shelf of Brazil. The subspecies was merely recorded in 1955, when Bernasconi described Centrostephanus besnardi (a synonym of C. longispinus rubicingulus), on the basis of two specimens collected at Trindade Island (State of Espirito Santo). This is the first record of this subspecies for northeastern Brazil (State of Rio Grande do Norte). A description is provided, along with comments on morphology and synonymy, illustrations of diagnostic characters and, for the first time, SEM figures of the pedicellariae of C. longispinus rubicingulus. An extended list of synonyms for the genus and species is included. This record raises the number of echinoids known from Northeastern Brazil to 32 species.
