Abstract: Corybas (Orchidaceae), a genus of some 100 species, is distributed from the Himalayas and southern China, through the Philippines, Malaysia, Indonesia and New Guinea, to Australia, New Caledonia, Tasmania, New Zealand and the islands of Polynesia. There are three recorded species in China, C. sinii Tang & Wang, C. daliensis Tang & Wang, and C. taiwanensis T. P. Lin & S. Y. Leu. In this paper, a new species, Corybas fanjingshanensis from Fanjing mountain nature reserve is described and illustrated. It is related to C. taliensis Tang & Wang, but differs by having rather short bract and lateral sepals and lacking lamellae on the disc. Its habitat and population size was reported in details.

Key words: Corybas, Corybas fanjingshanensis Y. X. Xiong, Orchidaceae, new species, distribution, Guizhou, China
