Abstract

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.
