title: Contribution to the knowledge of the oribatid mite genus Aeroppia (Acari, Oribatida, Oppiidae).
abstract: Two new species of the genus Aeroppia (Oribatida, Oppiidae) are described from upper soil and leaf litter in the primary evergreen lowland rainforest in Peru. Aeroppia friedrichi sp. nov. differs from A. nasalis Mahunka, 1984 by the absence of striate ornamentation on the notogaster and notogastral setae h1, and the presence of setiform adanal setae ad1. Aeroppia longisensilla sp. nov. differs from A. adjacens Mahunka, 1985 by the smaller body size and long bothridial setae. The supplementary descriptions of Aeroppia consimilis (Banks, 1910) and A. magnipilosa (Ewing, 1909) are presented, based on material from U.S.A. A new generic diagnosis for Aeroppia is given. The taxonomic status of the subgenus Aeroppia (Paraeroppia) Sanyal, 2009 is discussed, resulting in the following taxonomic proposal: Aeroppia Hammer, 1961 (=Aeroppia (Paraeroppia) Sanyal, 2009 syn. nov.).
