A new species of freshwater mussel belonging to the genus , namely , is diagnosed and described from Guangxi Province, China. This paper provides a detailed morphological description, photograph of the type specimen, and anatomical characteristics along with partial sequences of mitochondrial COI as DNA barcode data for this novel species. The new species can be distinguished from its congeners ( and ) by shell shape, beak position and surface sculpture. The interspecies genetic distance based on the COI barcode between and is 8%, while it reaches 9% with . 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。本文提供了详细的形态描述、模式标本照片、解剖特征以及线粒体COI的部分序列作为该新物种的DNA条形码数据。该新物种可通过壳形、喙的位置和表面纹饰与同属其他物种（ 和 ）相区分。基于COI条形码， 与 之间的种间遗传距离为8%，而与 的遗传距离达到9%。因此，我们提供了有力的形态学和分子证据来支持该新物种的有效性。
