Abstract
    Eosipho zephyrus, a new deep-water species from off the Chilean coast is described. Protoconch morphology distinguishes the new species from Cantharus aldermenensis Powell, 1971, a species commonly placed in the genus Eosipho Thiele, 1929. It is the first record of a member of the “Eosipho aldermenensis group” in the eastern Pacific. Generic allocation in Eosipho Thiele, 1929 versus in Manaria Smith, 1906 is briefly discussed. The presence of a third cusp on the lateral teeth of the radula is observed, compared to the same phenomenon in Manaria Smith, 1906 and Colus Röding, 1786, and considered to be an atypical morphology within the group rather than a feature warranting additional taxonomic separation.
