Resumo: | ABSTRACT Batillipes specimens collected in the Southwestern Atlantic Ocean, on the Brazilian Coast (Campos Basin and Potiguar Basin) with a bifurcated caudal appendage similar to B. dicrocercus Pollock, 1970 were assigned to B. potiguarensis Santos, da Rocha, Gomes Jr &amp; Fontoura, 2017. This species was described as having a roundish caudal protrusion but, as shown in this study, it exhibits intraspecific variability of the morphology of the caudal apparatus. The examination of specimens of B. dicrocercus from the type locality (Massachussetts, U.S.A.) and the analysis of the original description and two subsequent emended descriptions, one from the Gulf of Mexico (U.S.A.) and another from the Mediterranean Sea, used for comparison, revealed important differences among them concerning important taxonomic characters, suggesting that what was considered a single species should now be split into three different species. Therefore, an emended diagnosis of B. potiguarensis and comments on the geographic distribution of B. dicrocercus are provided, clarifying the taxonomic status of the two species.
