Trochita. pileus (Lamarck, 1822) and T. pileolus (d?Orbigny, 1841) are redescribed and the type material of each species is illustrated. Both species range from the coast of Buenos Aires province to Tierra del Fuego. Trochita. pileus is a common subtidal Patagonian species and T. pileolus is rare and usually lives in deeper waters. Trochita. trochiformis a Pacific only species is compare with the Atlantic representatives. Protoconch ornamentation and septum margin are the main differences between both Atlantic species.
