Helminthological examination of rodents revealed the occurrence of two Psilotrema species, P. simillimum (Mühling, 1898) and P. spiculigerum (Mühl

ing,1898) in Hungary. The hosts of P. simillimum were Arvicola terrestris and Pitymys subterraneus

, while P.spiculigerum parasitized Ondatra zibethica. The results of the author's investigations corroborate MERKUSHEVA

'

s statement, namely that P

. pharyngeatum Grabda, 1954, is the junior synonym of P

. simillimum

. On the basis of the author's examination, P.marki Skwortzow, 1934. is the junior synonym of P. spiculige rum (Mühling. 1898). In the course of the helminthological examination of rodents in Hungary, two Psilotrema species, P. simillimum (Mühling, 1898), and P. spiculigerum (Mühling, 1898) were found. Although both species were already known since the end of the last century, and though they have been found by many authors in Europe

, their systematical position is still not definitely clarified. The fluke species belonging to the genus Psilotrema Odhner, 1913, are parasites of birds and mammals. P. oligoon was described by LINSTOW (1887) from the small intestine of Gallinula chloropus

. Two further Psilotrema species were described by MÜHLING (1898) under the names P. spiculigerum and P. g-imill^ 3 2
