Abstract
Three new species of oribatid mites of the genus Plonaphacarus, Plonaphacarus sidorchukae sp. nov., Plonaphacams ry-balovi sp. nov. and Plonaphacarus hamulus sp. nov., are described from Bale Mountains National Park (Afrotropical region, Ethiopia). Morphological and taxonomical remarks about Steganacarus (Steganacams) sol and Steganacarus (Steganacarus) vestitus are presented. Ethiopia is the African country yet little explored as regards ptyctimous mites. Only three species are described to date (Niedbala 2001, 2008). In the course of faunistic studies of oribatid mites of Bale Mountains National Park (located in Ethiopia) we have found new species in the geneus Plonaphacarus Niedbala, 1986.
