R. Niemi & P. Skubala 1993: New Species of Moritzoppia and Medioppia From the Beskidy Mountains, Poland (Acarina, Oribatida, Oppiidae). - Entomologica Fennica 4: 195-200.
Moritzoppia sharipovi sp. n. and Medioppia beskidyensis sp. n. are described from Poland. M. sharipovi is distinguished from other species by the rostrum, sensilli, the crista and the large size. M. beskidyensis differs from all other species by the tubercles in the posterior margin of the prodorsum, the form of the rostrum, the number of genital hairs and the fusiform sensilli. A new combination, Medioppia ordunensis (Iturrondobeitia & Salona, 1988) comb. n. is presented.
