基于线粒体 COI 基因对日本的一组小型 Lottia 物种（Lottia kogamogai 复合体）进行了系统发育分析。结果，L. kogamogai 被细分为两个地理分支。洛蒂亚·科加莫盖 s. s。仅限于日本南部温带地区。以前被认为是该物种种内变异的北方种群现在被证明是一个独特的新物种，这里被描述为 Lottia goshimai n。 sp。这个新物种不仅在基因上，而且在齿状形态和贝壳雕塑上都与L.kogamogai不同。
A group of small lottiid species in Japan, the Lottia kogamogai complex, was phylogenetically analyzed based on the mitochondrial COI gene. As a result, L. kogamogai is subdivided into two geographic clades. Lottia kogamogai s. s. is limited to southern temperate Japan. The northern population formerly considered an intraspecific variation of the species is shown to be a distinct new species, here described as Lottia goshimai n. sp. The new species is distinguishable from L. kogamogai not only genetically, but in radular morphology and shell sculpture.
