1 Abstract: A long-term examination aimed at the recovery of amphistomes from Hungarian vertebrates has revealed eight species belonging to the families Diplodiscidae: Diplodiscus subclavatus (Goeze, 1782), Cladorchiidae: Opisthodiscus diplodiscoides Cohn, 1904 and Paramphistomidae: Paramphistomum cervi (Zeder, 1790); P. ichikawai Fukui, 1922; P. leydeni Näsmark, 1937; P. hibemiae Willmott, 1950; Calicophoron microbothrioides (Price et Mcintosh, 1944) and C. daubneyi (Dinnik, 1962). Key words: Amphistomes, Diplodiscidae, Cladorchiidae, Paramphistomidae, Hungarian vertebrates Amphistomes are widely distributed parasites of various vertabrates all over the world. From data of the European literature it was expected in advance that amphistomes would be found in two major group of vertebrates, amphibians and mammals (ruminants) also in Hungary. From different species of frogs two amphistomes, Diplodiscus subclavatus (Goeze, 1782) and Opisthodiscus diplodiscoides Cohn, 1904 were repeatedly described by various authors from the end of the last century and a new subspecies, O. diplodiscoides nigrivasis Méhely, 1929 was added to these species. Studies on the amphistomes of wild ruminants continued from the 1970s and these examinations revealed four species, Paramphistomum cervi (Zeder, 1790), P. ichikawai Fukui, 1922, P. leydeni Näsmark, 1937 and P. hibemiae Willmott, 1950 in red deer, roe deer and fallow deer. Since the beginning of this century some papers have been published on the amphistome species of domesticated ruminants. Moreover, for some decades ectensive research work has been done to reveal the species of amphistomes parasitic in these ruminants and their ecology: Paramphistomum {^Calicophoron) microbothrium Fischoeder, 1901; P. microbothrioides Price and Mc Intosh, 1944 (in the sense of Kotlán 1958); C. daubneyi (Dinnik, 1962), Paramphistomum cervi, P. ichikawai, P. leydeni and P. hibemiae Willmott, 1950 have been recovered from cattle, sheep and buffaloes. More recently, Calicophoron microbothrioides, found in cattle imported from North America, has been added to this list. 1 Department of Zoology, Pannon University of Agricultural Sciences, Keszthely, Hungary
