Three species of Parthenina (Chrysallidinae, Pyramidellidoidea) new to West Africa

Three species of pyramidellid gastropods, Parthenina suturalis (Philippi 1844), Parthenina flexuosa (Monterosato 1874) and Parthenina feldi (Aartsen et al. 2000), are reported from off West Africa for the first time. This represents a considerable increase in distribution range for all species, and indicates that the pyramidellid fauna of West Africa is still incompletely known in spite of several studies published in recent years. The shell morphology of the three species are described.
