Paraphlomis leigongshanensis G.B. Jiang & W.H. Yao (Lamiaceae), a new species endemic to Leigong Mountain National Nature Reserve (Guizhou, China), is described and illustrated. Morphologically, it is most similar to P. jiangyongensis, but can easy be distinguished by its lamina shape, calyx teeth shape, and corolla color. A close relationship between the new species and P. gracilis var. lutienensis was revealed by molecular phylogenetic analyses based on ETS and ITS sequences, but they are morphologically distinct from each other. With only three known populations (ca. 200 mature individuals) in subtropical evergreen forests, the new species is assessed as Endangered (EN) under IUCN criteria B2ab(iii); D.
