and hooks. Suckers 85-120 p in diameter. Number of hooks 18-21, length 18-20 u, of a characteristic shape (Fig. 1A). In young segments testes form a triangle, but in mature segments one situated poral, two aporal in line. Cirrus pouch 200-330x60 p.. Cirrus 100 p long, 30 u broad, covered with fine deciduous spines. Ovary 200-400 p in diameter, receptaculum seminis 350x100 p. Eggs spherical, 45-67 p. Oncosphere 20-30 p, embryonal hooklets 8-5-9 p (Pig. 2), This species has been investigated in detail by TENORA and MURAI (1972). In Czechoslovakia it parasitizes also Apodemus species (ERHARDOVÁ, I960; TENORA, 1965), in Hungary, however, it has been found only in voles until now.
