A new species, Petrocodon confertiflorus H.Q. Li & Y.Q. Wang (Gesneriaceae) from Guangdong Province in south China, is described and illustrated. It is most similar to P. dealbatus, but is distinct from its congeners by its bigger ovate-oblanceolate leaf blade with 6–12 pairs of lateral nerves, by the number of cymes (3–10) with 2–3 branches bearing densely placed flowers, by the swollen, urceolate corolla with a constricted orifice, by the stamens adnate to the corolla and with the anthers free, as well as by the leaf epidermal characters.
