The genus Mitrolumna (Gastropoda, Turridae) in West Africa

Five species of Mitrolumna Bucquoy, Dautzenberg and Dollfus, 1883, are identified from West Africa, mostly from recent unpublished findings. Three species from Senegal, already known, are revised: M. monodi (Knudsen, 1956), M. cf crenipicta Dautzenberg, 1889 and M. smithi (Dautzenberg and Fischer, 1896). Two species are described as new for science: Mitrolumna senegalensis spec. nov. from Senegal and Mitrolumna saotomensis spec. nov. from São Tomé, Príncipe and Annobón.
