This species with a medium-size shell for the genus (14–16 mm) was initially sampled during a baseline project that studied marine biotopes in the central Algarve region. This short note presents a brief diagnosis of the species, provides local information on geographical distribution, habitat, and compares it with other congeneric species found in Portugal: Ocinebrina aciculata (Lamarck, 1822) and Ocinebrina edwardsii (Payraudeau, 1826).engNorth-Eastern AtlanticSouth PortugalGastropodaMuricidaeOcenebrinaeOcinebrina nicolaijournal article10.1017/S1755267210000631
