Three new marginellid gastropods (Muricoidea: Marginellidae: Granunilinae) from the Red Sea and Djibouti (Gulf of Aden)

A new species of Marginellopsis Bavay, 1911, Marginellopsis herosae n. sp. and two new species of Granulina Jousseaume, 1888, Granulina morassii n. sp. and Granulina boyeri n. sp. are described and illustrated from the Red Sea and Djibouti. Marginellopsis herosae n.sp. represents the first Indo-Pacific record of a genus previously known by only one species from Cuba, Caribbean Sea. The biogeographic relevance of this finding and the possible Tethyan origin of the genus Marginellopsis is suggested. Micrographs of the type specimens of Granulina isseli (G. Nevill & H. Nevill, 1875), Granulina mariei (Crosse, 1867), Granulina cartwrighti (Sowerby, 1915) and Marginellopsis serrei Bavay, 1911 are provided
