However, examination of several specimens collected from İzmir Bay (Aegean Sea) revealed the presence of a further species, which is here described as Bacteridium izmirensis sp. nov. In this study, the new species is examined in detail and compared to the other similar species, with comments on the distinctive features of the new species. KW - Bacteridium izmirensis sp. nov. KW - Mollusca KW - Türkiye N2 - Bacteridium Thiele, 1929 genusu dünya okyanusunda yaşadığı bilinen 5 tür içermektedir. Ancak İzmir Körfezi’nden toplanan bazı bireylerin incelenmesi sonucu, Bacteridium izmirensis sp. nov. olarak tanımlanan başka bir türünde olduğu tespit edilmiştir. Bu çalışmada, yeni tür ayrıntılı olarak incelenmiş ve benzer türler ile karşılaştırma yapılarak, ayırt edici özellikleri hakkında açıklama ve yorumlarda bulunulmuştur. CR - Adams, A. (1861).
