A putative new limpet species (Patellogastropoda) from the Sea of Japan is revealed by molecular genetic analyses using the mitochondrial markers rRNA and subunit I (), as well as the DNA marker rRNA. Our data indicate that the limpet, collected in the Peter the Great Bay (Russian Federation), is not, as its morphology suggests, the Japanese species Sasaki and Okutani, 1994, and might also hint towards another putative species complex in the Sea of Japan. The different currents between the Far East Asian mainland (cold, subpolar jet running southwards) and the Japanese archipelago (warm, subtropical jet running northwards) are likely to act as a barrier that has a substantial influence on species distribution in these waters. Accordingly, our results indicate that it is about time for a revision of patellogastropod species with a reported distribution in Japanese and Far Eastern Russian waters by an integrative approach using molecular genetic and morphological characters. The species investigated herein is referred to as cf. until it is morphologically re-examined and compared with primary type specimens of known species.
利用线粒体标记rRNA和亚基I以及DNA标记rRNA进行分子遗传学分析，揭示了一种来自日本海的疑似新帽贝物种（笠贝亚纲）。我们的数据表明，在俄罗斯联邦彼得大帝湾采集的这种帽贝，并非如形态学所显示的那样是1994年命名的日本物种Sasaki and Okutani，这也可能暗示着日本海存在另一个疑似物种复合体。远东亚洲大陆（向南流动的寒冷亚极地急流）和日本群岛（向北流动的温暖亚热带急流）之间不同的海流，可能构成了一道屏障，对这些海域的物种分布产生了重大影响。因此，我们的结果表明，现在是时候通过综合运用分子遗传学和形态学特征的方法，对报道分布于日本和俄罗斯远东水域的笠贝亚纲物种进行修订了。在对本文所研究的物种进行形态学重新检查并与已知物种的模式标本进行比较之前，暂时将其称为cf. 。
