In some early years before 1984, Y. Kuwahara (1966,1968), a Japanese bryologist, recognized this group to be distinct and treated it under four genera: Metzgeria Raddi., Apometzgeria Kuwah., Austrometzgeria Kuwah., and Apertithallus Kuwah.The present study concerns the family Metzgeriaceae in China, especially in South west-ern China. 7 species, 1 subspecies and 1 variety belonging to two genera are discussed and illus-trated, among which, the M. darjeelingensis Kuwah. and M. novicrassipilis Kuwah. are new re-cords in China. Also the key to species is given.
