The present study is based on oribatid mite (Oribatida) materials collected from Menagesha Suba State Forest and Borena National Park (Oromia region, central and southern Ethiopia). A list of 65 species belonging to 45 genera and 32 families is presented; new records for the Ethiopian and Afrotropical fauna are provided. Two new species—Aleurodamaeus westshewaensis Ermilov sp. nov. (Aleurodamaeidae) and Diplobodes borenaensis Ermilov sp. nov. (Carabodidae)—are described; A. westshewaensis differs from the related species A. angelae in body size, the length of the notogastral setae, the location of the aggenital and adanal setae, and number of setae on the leg tarsus IV; D. borenaensis differs from the related species D. superbus in body size, the surface of the prodorsum and notogaster, the morphology of the translamella, and the notogaster form.
