This study provides an updated morphological description of Asteroporpa (Asteroporpa) annulata based on one specimen from the northeastern coast of Brazil, thus validating the previously uncertain occurrence of this species there. We also provide notes on the known geographic distribution of the subgenus Asteroporpa (Asteroporpa) and comments on ecological aspects of this taxon. Given our limited knowledge of the Euryalida fauna along the Brazilian coast, these new records are important for understanding the distribution, dispersal and speciation patterns of this group. The number of Euryalida reported for the Brazilian coast is increased to eight with this record.
