A new species of cestode, Biuterina cordifera sp. n. is described from warblers (Acrocephalus schoenobaenus, A. scirpaceus and Lusciniola melanopogon) inhabiting reeds of sodic lakes in the Great Hungarian Plain. KEY WORDS: Cestoda, Biuterina cordifera sp.n. , morphology, Passeriformes: Sylviinae, Hungary. The staff of the Hungarian Natural History Museum carried out a systematical research programme between 1977 and 1981 on the fauna of protected regions of the lowland between the rivers Danube and Tisza, which comprise the Kiskunság National Park. A large number of birds were dissected for parasitological examination during the course of this study (MURAI SULGOSTOWSKA - MATSKÁSI - MÉSZÁROS, in press). Among the cestodes a species new to science, Biuterina cordifera was found, which is described below. MATERIAL AND METHOD Birds are strictly protected in Hungary so they are not readily obtainable for parasitological examination. Therefore our collecting work was coordinated with the organized bird migration studies carried out in the Kiskunság National Park. The birds are netted for banding, and though meticulous care is taken, there is always a loss of a few percent of the birds. The dead specimens were dissected either fresh or after a few weeks of storage in deep-freezer. The worms were fixed in 5% hot formaldehyde solution. The in toto préparâtes were stained with Erlich' s haematoxylin, for a few proglottis we used alun-carmin. The hooks and eggs were examined in Berlese medium. The host species of the new paruterinid species are various warblers (Sylviinae - typical warblers). All the specimens were found to parasitise Lusciniola melonopogon (moustached warbler), Acrocephalus schoenobaenus (sedge warbler) and Acrocephalus scirpaceus (reed warbler) from the large reedbeds surrounding the sodic lakes (Szivós-szék) around Fülöpháza. Specimens of Acrocephalus arundinaceus from the same locality were also dissected but no B. cordifera was found parasitising that species. Warblers from other regions of the Kiskunság National Park (Apajpuszta, Szabadszállás), did not harbour any parasites. For comparative material we used the Biuterina passerina Fuhrmann, 1908 material from Emberiza citrinella (Passeridae) from the Bakony Mountains (Szentgál, 2-16 July, 1952 col-
