Abstract: The southern African genus Burnupena lredale, 1918, in the gastropod family Buccinidae has presented ongoing taxonomic problems because of morphological plasticity and the existence of forms that are intermediate between species. Based on morphological and genetic analyses, seven species can be recognised. In this paper we provide taxonomic descriptionptions of these species, including the merging of two previously recognised species as subspecies (Burnupena cincta cincta (RA¶ding, 1798) and B. cincta limbosa (Lamarck, 1822)), and the recognition and descriptionption of two new species (B. rotunda and B. denseliriata).
