Hermonassa nigricans sp. nov. is distributed in Nepal and China, and the Himalayan species H. kalamantra Kovács, G. Ronkay & L. Ronkay, 2018 is re-orded for China for the first time. The occurrences of H. anthracina Boursin, 1967 in Nepal is questionable taking in the account the presence of two externally hardly distinguishable species, H. kalamantra and H. nigricans sp. nov.
