Petrocosmea chrysotricha M.Q.Han, H. Jiang & Yan Liu, a new species from Yunnan, China, is described and illustrated. Petrocosmea chrysotricha was found growing with P . melanophthalma on damp marlstone cliffs in evergreen broad‐leaved forest on Mopan Shan. The new species has been grown for decades by Gesneriad enthusiasts under the name P. begoniifolia for decades and it is indeed similar to P . begoniifolia in its oblique campanulate corolla tube, but differs by having filaments covered with golden lanate indumentum in the middle part and by having primrose yellow flowers at the beginning if anthesis, then turning white.
