). As a major ecological barrier in southwest China, Guangxi is one of the significant watershed areas of the Pearl river basin. The province is noted for its distinctive karst landscape which harbors a rich diversity of species. However, due to the insufficient attention paid to freshwater mussels in the region, the mussel diversity in China is poorly understood. The lack of data regarding

distributions, population trends, threats, and accurate taxonomic information has severely impeded conservation efforts for the unionids in this area. Our findings suggest that there is still much to be discovered regarding the diversity of freshwater mussels in Guangxi Province. Additional extensive exploration may reveal other species that have yet to be documented.
