The present study is based on oribatid mite material (Acari, Oribatida) collected from soil of Kaaimansgat estuary, Wilderness, Western Cape, South Africa in 2018. A list of identified taxa, including 41 species from 34 genera and 23 families, is presented; of these, nine species, three genera and one family are recorded in South Africa for the first time. Two new species belonging to the family Oppiidae are described: Kokoppia kaaimansensis sp. nov. differs from Kokoppia dudichi (Balogh, 1982) by the larger body size, the medium sized lamellar and interlamellar setae, the presence of muscle sigillae in the interlamellar region and the distinctly semi-oval epimeral borders IV and the absence of notogastral setae c; Paroppia neethlingisp. nov. differs from other species of the genus by the localization of adanal lyrifissures in a direct apoanal position and the absence of epimeral borders IV. Revised generic diagnoses and identification keys to the known species of Kokoppiaand Paroppia are presented.
