The morphology of juvenile stages of the oribatid mites Pedrocortesella africana Pletzen, 1963 and Aleurodamaeus africanus Mahunka, 1984 is described and illustrated. The juveniles of Pedrocortesella africana are characterized by: cuticle with reticular ornamentation and folds; body with microgranular cerotegument; prodorsal setae leaf-shaped, sensilli petiolate, tuberculate blades with a rounded distal margin; gastronotic region flat; larva and nymphs with nine pairs of leaf-shaped gastronotic setae; scalps folded, larval scalp with seven pairs of setae, nymphal scalps with six pairs of setae; leg famulus sunken. The juveniles of Aleurodamaeus africanus are characterized by: cuticle smooth; body with filamentous cerotegument and with very not numerous granules; prodorsal setae setiform (except short interlamellar setae in nymphs); gastronotic region convex in lateral aspect; larva and nymphs with 12 of setiform gastronotic setae; scalps with reticular ornamentation, larval scalp with nine pairs of setae, nymphal scalps with ten pairs of setae; leg famulus emergent. The comparative analysis between known juveniles in Plateremaeoidea and Gymnodamaeoidea are given.

Two new species of oribatid mites of the subgenus Austrocarabodes (Uluguroides), A. (U.) arboreus sp. nov. and A (U.) aethiopicus sp. nov., are described from Ethiopia. The former species was obtained in mosses on trees from Cholomu Forest (10 km to the south from Ginchi city); the second species was obtained from soil from Harenna Forest (Bale Mountains National Park). Both new species differ from all known species of the subgenus by presence of eight to nine pairs of genital setae (five-six in other species). A diagnostic key to African species of Austrocarabodes (Uluguroides) is presented.

We described Machadobelba shtanchaevae sp. nov. and Microtegeus khaustovi sp. nov., collected in Bale Mountains National Park (Africa, Ethiopia). The first new species is similar to Machadobelba symmetrica Balogh, 1958 (Distribution: Africa, Congo) and to Machadobelba ceylonica Balogh, 1970 (Asia, Sri Lanka), but differs from the former species by body size, length of costulae and length of notogastral setae, and from the latter species by body size, morphology of cristae and position of adanal setae ad3. Microtegeus khaustovi sp. nov. is similar to Microtegeus variabilis Mahunka, 1988 (Africa, Tanzania) and Microtegeus rugosus Mahunka, 1982 (Africa, Ethiopia), but differs from the former species by body size, number of prodorsal tubercles, length of notogastral setae c, and morphology of the notogaster; from the latter species it differs by morphology of lamellar setae, the number of prodorsal tubercles, and morphology of the notogaster.
