Two species of the genus Boysidia Ancey, 1881 were reported as new to science, Boysidia (Boysidia) xianfengensis sp. nov. and B. (B.) xiaoguanensis sp. nov., while the distribution of the 23 species of Boysidia from China was discussed. The materials of the new species were collected from Hubei Province, China by authors. The shell of B. (B.) xianfengensis sp. nov. looks small (height 4.90 mm, diameter 3.10 mm), and has five apertural teeth: one large parietal tooth, one long columellar tooth, one small nipple-shaped upper palatal tooth, one large flake-shaped lower palatal tooth, one small infrapalatal tooth. The shell of B. (B.) xiaoguanensis sp. nov. looks small (height 3.55 mm, diameter 2.20 mm), and has four apertural teeth: one large parietal tooth, one long columellar tooth, one large flake-shaped upper palatal tooth, one slightly small flake-shaped lower palatal tooth. The type specimens of the new species are deposited in the Institute of Zoology, Chinese Academy of Sciences, China.
