A new species of freshwater mussel belonging to the genus , namely , is diagnosed and described from Guangxi Province, China. This paper provides a detailed shell morphological description, soft-body anatomical characteristics, and partial sequences of mitochondrial COI as DNA barcode data for the novel species. The new species can be distinguished from its congeners (, , and ) by shell shape, beak position, and surface sculpture. Phylogenetic analyses based on the mitochondrial COI gene reveal that forms a sister group with and exhibits an interspecific genetic distance of 5.1%. Therefore, we provide robust morphological and molecular evidence to support the validity of this new species.
一种隶属于 属的淡水贻贝新物种，即 ，在中国广西被鉴定并描述。本文提供了该新物种详细的贝壳形态描述、软体解剖特征，以及线粒体细胞色素氧化酶亚基I（COI）的部分序列作为DNA条形码数据。该新物种可通过贝壳形状、喙的位置和表面纹饰与同属其他物种（ 、 和 ）区分开来。基于线粒体COI基因的系统发育分析表明， 与 形成姐妹群，种间遗传距离为5.1%。因此，我们提供了有力的形态学和分子证据来支持这一新物种的有效性。
