Seven micromorphic brachiopod species belonging to six genera are identified in Middle and Upper Eocene deposits from north-western Hungary. One species is new, namely Argyrotheca tokodensis sp. nov. The species Novocrania bayaniana (Davidson, 1870), Orthothyris pectinoides (von Koenen, 1894), Argyrotheca michelottina (Davidson, 1870) and Lacazella mediterranea (Risso, 1826) are reported for the first time from the Hungarian Eocene localities, while Terebratulina tenuistriata (Leymerie, 1846) and Megathiris detruncata (Gmelin, 1791) were already noted from the Eocene deposits of Hungary.
