They are Oxybrachioppia glabriseta sp.nov. belonging to the family Oppiidae Grandjean and Umbellozetes squamaceus sp.nov. and U. combinatus sp.nov. belonging to the family Tegoribatidae Grandjean. The new species were collected from alpine meadow, mosses and forest litter, lichens on stones and thin soils, respectively. The holotypes are deposited in the Institute of Zoology, Academia Sinica, Beijing, China.
