ABSTRACT. A new species of Gymnomitrion, G. schusteranum is described based on specimens from the Sino-Himalaya (South-west China and North India). It differs well from other species of the genus by the presence of a pronounced vitta not known in any other Gymnomitrion spp., as well as its distinctly elongate leaves with unequal lobes, very deep sinus, and revolute margins of sinus and margins of leaves. So far, the species has been found in in China in an area with a concentration of other endemic and subendemic Sino-Himalayan liverworts and in West Bengal (India) located ca. 1000 km apart.
