A new species in Gesneriaceae, Petrocosmea miechangensis, is described from southeastern Yunnan, China. This species bears a resemblance to P. sericea in the shape of the adaxial corolla lip and in having very densely appressed hairs on the abaxial leaf blade. However, it can be distinguished by its flowering period, the hairs on the leaf blade, calyx, and filaments, as well as the shape of the filaments. An identification key to P. miechangensis and its related species is presented.
