The genus Ptilophora Stephens in China is briefly reviewed, with the description of Ptilophora nanlingensis sp. n. The new species is most similar to Ptilophora horieaurea in wing pattern and to Ptilophora jezoensis in male genitalia, but they can be distinguished from each other by the following characters: forewing bright reddish brown in Ptilophora nanlingensis, chestnut brown in Ptilophora horieaurea; costa of male genitalia pointed, with a rounded subapical process ventrally in Ptilophora jezoensis, costa rounded, with apex inflated, and with pointed subapical process ventrally in Ptilophora nanlingensis. A key to the Ptilophora species from China and adjacent areas is presented and a distribution map is given. The holotype of the new species is deposited in the Department of Entomology, South China Agricultural University, P. R. China.
