Three East-Asian species of the hepatic genus Scapania, namely, S. parvidens Steph., S. parvitexta Steph., and S. glaucoviridis Horik., which were recently treated as one species (S. parvidens) by Potemkin, are described and typified. Examination and comparison of the types as well as representative specimens showed that these three should be treated as separate species. Descriptions with figures for each species are presented and differences among the three species are discussed in detail.
