A new species of intertidal limpet was identified from Yonaguni Island, Japan and southern Taiwan in the present study and described as n. sp. It was previously reported by different authors as , or as Acmaeid sp. in Taiwan, and as sp. in Yonaguni Island, Japan. Based on detailed morphological observations and molecular analyses (), n. sp. is distinguished from other species. n. sp. is presently known from southern Taiwan, and a population on Yonaguni Island, Japan that is very limited. The present study reports a total 11 species of patellogastropod limpet species in Taiwan. The seven species-, , , , , and -were found in the intertidal on rocky shores along the north to northeastern shores of Taiwan. The five species-, , , and n. sp.-can be found mostly within depressions in limestone substrate in southeastern Taiwan. Of these, only is found throughout Taiwan, and overall has a tropical, not warm-temperate, distribution.
在本研究中，一种新的潮间带笠贝物种在日本与那国岛和中国台湾南部被鉴定出来，并被描述为新物种。此前不同作者曾将其在台湾报道为 ，或 Acmaeid 属物种，在日本与那国岛报道为 属物种。基于详细的形态学观察和分子分析（），该新物种与其他笠贝物种相区分。目前已知该新物种分布于中国台湾南部以及日本与那国岛一个非常有限的种群。本研究报告了台湾总共11种笠贝目笠贝物种。七种物种—— 、 、 、 、 、 和 ——在台湾北部至东北海岸的岩石海岸潮间带被发现。五种物种—— 、 、 、 和该新物种——大多可在台湾东南部石灰岩基质的凹陷处找到。其中，只有 在台湾各地均有发现，总体上具有热带而非暖温带的分布。
