Herbertus ramosus (Steph.) H.A.Mill. and H. sendtneri (Nees) Lindb. are described and illustrated from West Siang District of Arunachal Pradesh in the eastern Himalaya, India. This constitutes the first record of H. ramosus in Indian bryoflora. It is easily distinguished from hitherto known Indian species of the genus by orange brown plants having falcate leaves with acute leaf lobes 23–40 cells wide at base, up to 8 cells uniseriate towards apex, strongly expanded basal leaf lamina on dorsal side, and strong grooved vitta. Identification key to the Indian species of the genus is provided and its distribution in the country is discussed.
