In this study, two new species of the leaf-beetle genus Paleosepharia Laboissière, 1936 from China are described: P.subrubra Feng, Yang & Ge, sp. nov. and P.emeiensis Feng, Yang & Ge, sp. nov. Meanwhile, Paleosephariatruncata Laboissière, 1936 is first recorded for China. Additionally, Monoleptabicavipennis Chen, 1942 and Monoleptaquadricavata Chen, 1976 are redescribed and proposed as new combinations under Paleosepharia. A key to the Chinese species of Paleosepharia is also provided.
