Abstract: A recently extinct new genus and species of freshwater mussel, Gigaunio sichuanensis Z.-G. Chen, Y.-T. Dai, X. Liu & X.-P. Wu gen. & sp. nov., is described from the Minjiang River in Sichuan, China. The species was last recorded alive in 1964 and is now considered fully extinct, with even fresh empty shells no longer being found. The discovery increases the diversity of freshwater mussels in the upper Changjiang River and indicates the urgency of taking protective measures for freshwater mussels in the region.
