Syntypes of Macvicaria pennelli (Leiper et Atkinson, 1914) and Allocreadium fowleri Leiper et Atkinson, 1914 are re-examined and a new material from the Ross Sea is described. A. fowleri is considered identical with M.pennelli in the immature stage. Digeneans occurring in the Western Antarctic regarded by various authors as M. pennelli are considered as belonging to a separate species. The name M. georgiana (Kovaljova et Gaevskaya, 1974) comb. nov. is proposed for them. The species differ in sucker ratio and arrangement of vitelline follicles between the ventral sucker and gonads. M. pennelli occurs in the sub-continental zone of the Eastern Antarctic, while M. georgiana occurs in the Western Antarctic, at South Georgia, South Orkney Islands, South Shetland Islands and Antarctic Peninsula. A key to five representatives of the genus Macvicaria reported from the Antarctic fishes is included.
