Two new species of oribatid mites of the family Oppiidae collected from leaf litter in Madagascar are described. Ramuselloppia indistinctasp. nov. differs from Ramuselloppia anomala by larger body size, the presence of epimeral tubercles and comparatively long lamellar, interlamellar and notogastral setae and the absence of costulae and heads of bothridial setae. An identification key to known species of Ramuselloppia is provided. Lanceoppia (Baioppia) rugosasp. nov. differs from all species of the subgenus by heavily rugose posterior part of the notogaster. The genus Ramuselloppia and subgenus Lanceoppia (Baioppia) are recorded in the Ethiopian region for the first time; the species Multioppia (Hammeroppia) wilsoni is recorded in Madagascar for the first time.
