The present study is based on material collected during a two-month Russian- Ethiopian expedition in October and November 2011. An annotated checklist of identified oribatid mite taxa is presented. Two new oribatid mites of the family Oppiidae, Separatoppia concava sp. nov. and Ramusella (Rectoppia) ginchiensis sp. nov., are described from moss of Cholomu forest (Southern Ethiopia). An identification key to all known species of Separatoppia is given. Eighteen species, 11 genera and two families are recorded for the first time from Ethiopia. The genus Furcoribula and species Trhypochthonius tectorum and Furcoribula furcillata are recorded for the first time from the Ethiopian region.

The morphology of juvenile stages of the oribatid mites Metabelba glabriseta Mahunka, 1982 and Damaeus auritus Koch, 1835 (Damaeidae) is described and illustrated. The juveniles of Metabelba glabriseta are characterized by: cuticle smooth, with rare folds and also with slightly developed reticulate ornamentation dorso-laterally; cerotegument of body with conical or strongly oblong granules, that of some body setae cloud-like; rostral and lamellar setae of approximately identical length, with hardly developed barbs; sensilli with long flagellate tips, smooth; gastronotic region rounded posteriorly; almost all gastronotic setae with small flagellate tips, barbed, setae lp longest in larva, setae c1, c2, h1 longest in nymphs; cornicle k of nymphs long, slightly curled, distally slightly swollen and longitudinally split; all legs of juveniles shorter than body; setae d and v” on trochanter III appear in adult; famulus emergent. The juveniles of Damaeus auritus are characterized by: cuticle smooth, with rare folds; cerotegument of body with spherical granules, body setae without cerotegument; prodorsal setae barbed, setae ex and larval setae in short, strong, sensilli thickened, but with thin, bent tips; gastronotic region truncate (in larva) or rounded (in nymphs) posteriorly; some gastronotic setae vane-like; cornicle k of nymphs short, strong, conical; all legs (except II in nymphs) of juveniles longer than body. Famulus sunken. Juveniles are compared among the known species of Metabelba and Damaeus, and also among the genera Metabelba, Damaeus and Epidamaeus.

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.

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.

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.
