Summary:Petrocodon asterostriatus F. Wen, Y.G. Wei & W.C. Chou sp. nova (Gesneriaceae) is described and illustrated. It is a lithophytic species that grows in the limestone area of southwestern Guangxi, China. According to the maximum likelihood (ML) analysis, it nests in a strongly supported clade (BP = 92%) that includes P. lui, P. tiandengensis, P. integrifolius, P. albinervius and P. ionophyllus. Of these, P. asteriostriatus is morphologically closest to P. integrifolius, but can be distinguished from it by the shape and size of bracts, the indumentum of the pedicel, the shape and indumentum of the corolla tube, the shape of the lip lobes, and the indumentum and glands of filaments.
