The present study is based on oribatid mite material collected from litter in highlands bamboo location in Bale Mountains National Park, Southeastern Ethiopia. A list of 35 species belonging to 27 genera and 19 families is presented; of these, Nothrus berlesei and Dolicheremaeus capillatus neonominatus are recorded in Ethiopia for the first time. Two new species—Coronabelba pustulata Ermilov sp. nov. and Suctobelbila quattuor Ermilov sp. nov.—are described. Coronabelba pustulata differs from the other congeneric species by the presence of densely tuberculate dorsal part of the notogaster, bordered by two longitudinal ridges. Suctobelbila quattuor differs from the other congeneric species by the presence of four longitudinal cerotegumental bands represented by sparse granules connected by cerotegumental cords on the notogaster.
