Abstract Two new species, Sinoarinia feii Chen, gen. et sp. nov. and Pincerna vallis Chen & Wu, sp. nov., are described from western Hubei, China. The new genus Sinoarinia Chen & Wu, gen. nov. is established based on the strongly constricted penultimate whorl and the ascending last whorl. The Vietnamese species Pincerna costulosa (Bavay & Dautzenberg) is newly reported from Yunnan, China. For comparison, photographs of the shells of closely related species are provided. A key to the known species of Sinoariniagen. nov. is included.
