Epitonium (Parviscala) vaillanti (Jousseaume, 1912), a species previously known only from the Red Sea and Gulf of Aden, is recorded for the first time in the Mediterranean Sea. This new Erythrean alien was found in the course of examination of unidentified specimens from Mediterranean coast of Israel, showed morphological features unknown to any previously recorded Mediterranean epitonid species. To confirm identification, morphological comparison with the syntypic serie of Avalitiscala vaillanti Jousseaume, 1912, stored in the Museum d’Histoire Naturelle de Paris (MNHN) was performed and some remarks of the taxonomy of the species are discussed. |
