The syntypes of Biuterina passerina Fuhrmann, 1908 from Alauda arvensis and Galerida cristata (Passeriformes, Alaudidae) from an unknown locality are redescribed. B. fuhrmanni Schmelz, 1941 is redescribed on the basis of its syntypes from Emberiza aureola from China; its type-material contains, in addition to a scolex and pre-gravid and gravid fragments of Biuterina, fragments of mature proglottides from a dilepidid cestode, which were erroneously used in the original description. Specimens, which correspond morphologically to B. clerci Spasskii, 1946, from Miliaria calandra, E. citrinella and E. cirlus from Bulgaria and from E. citrinella from the Czech Republic, are studied. The synonymy of B. clerci with B. passerina is rejected; however, it is recognised as a synonym of B. fuhrmanni. Available data suggest that B. passerina is a specific parasite of birds of the family Alaudidae, while B. fuhrmanni is specific to the Emberizidae. B. collurionis Matevosyan, 1950 is considered a species inquirenda, pending confirmation of apparent differences from B. passerina and B. fuhrmanni based on further material. Biuterina cordifera Murai & Sulgostowska, 1983 is redescribed on the basis of specimens, previously identified by Rysavý (1965) as B. triangula (Krabbe, 1869), from Acrocephalus scirpaceus (Muscicapidae, Sylviinae) in the Czech Republic (new geographical record) and from Erithacus megarhynchos (Muscicapidae, Turdinae) in Bulgaria (new host and geographical records).
