title: [Aythya fuligula--new host for Retinometra pittalugai Lopez-Neyra, 1932 (Cestoda, Hymenolepididae) recorded in Poland for the first time].
abstract: During standard parasitological studies of the tufted duck Aythya fuligula (Linnaeus, 1758), obtained from fishermen from West Pomerania, three cestode specimens were found in the jejunum of hosts. They were determined as Retinometra pittalugai (Lopez-Neyra, 1932) on the basis of the cirrus's size, shape of stylet and rostellar hooks. This is the first record of this species in Poland, since this parasite was earlier recorded only in Anas platyrhynchos f. dom., Aythya marila, A. ferina and Bucephala clangula in Spain, in Kamchatka and in Novosibirsk.
