The species of the genus Volvarina (Gastropoda, Marginellidae) from coastal Angola are reviewed. V. ameliensis (Tomlin, 1917) is representative of a complex including several similar morphotypes, among which V. riparia n. sp. is recognized as a distinct species; further research may lead to the recognition of more species. Two other new species, V. fugax and V. peregrina, not related to this complex, are also described.
Résumé: Les espèces du genre Volvarina (Gastropoda, Marginellidae) du littoral de l’Angola sont révisés. V. ameliensis (Tomlin, 1917) est reprèsentative d’un complexe comprenant des morphotypes très similaires, parmi lesquels nous reconnaissons V. riparia n. sp. comme espèce distincte; des recherches à venir pourraient permettre de reconnaitre d’autres espèces. Deux autres espèces noovelles, V.fugax et V. peregrina, qui n’entrent pas dans ce groupe, sont aussi dèrites.
