Oreocharis corallodiscoides, a new species of the tribe Trichosporeae (Gesneriaceae), is described and illustrated. This new species is characterized by its ovate, rounded or sometimes rhombic leaves densely covered with appressed hairs, yellow corolla, and the presence of two purple triangular appendages inside the base of the corolla tube. It is known only from the type locality, Luzhijiang dry-hot valley in Yimen county, central Yunnan, southwest China. A morphological comparison with its morphologically similar species (O. agnesiae and O. longifolia) is also presented.
