A new species of tardigrade (Eutardigrada: Isohypsibiidae) was discovered in moss in the Wuyi Mountains, Fujian Province, southeastern China. Doryphoribius mcinnesae, new species, belongs to the evelinae group because it has two macroplacoids and displays cuticular gibbosities. The surface of the body on the dorsal and lateral sides is sculptured with a reticular formation. The first macroplacoid is longer than the second one; lunules and cuticular bars on legs are absent. It differs from the other members of the group by having a different gibbosity configuration (X: 2-3-1-3-1-3-1-2-2-2) or cuticular sculpture. The paper includes a detailed comparison of the new species with other similar but different species.
