VERIFICATION OF FEATURES OF THE GENUS FIMBRIARIA (FROELICH, 1802) ANDA KEY TO THE IDENTIFICATION OF SPECIES

Knowledge to dale on the morphology of Fimbriaria tapeworms is summari sed, with features of the genus being verified and augmented by some n ot previously taken account of, like the ultrastructure of the tegumen t. The most important features in accurate identification to the level of the species are the structure of the oncospheral envelope and the manner in which eggs are released from the uterus. Other features of d iagnostic importance are the number of primordia of reproductive organ s, the number of hooks at the cirrus base and the dimensions of the ci rrus and cirrus pouches.
