Petrocodon anoectochilus F. Wen & B. Pan, a new species of Gesneriaceae from Guangxi and Guizhou in southwestern China, is described and illustrated. Although the leaf morphology of this new species looks similar to that of P. coriaceifolius (Y. G. Wei) Y. G. Wei & Mich. Möller and P. pseudocoriaceifolius Yan Liu & W. B. Xu, this remarkable new species can be easily distinguished from all other species of Petrocodon s.l. (the two above-mentioned species included) by the shape and color of its memorable corolla. Because of its restricted distribution and threatened environment, the current conservation status of this species should be assessed temporarily as “Endangered.”
