ABSTRACT: Gravid females of Philometroides were found under the scales of stock carp Cyprinus carpio L. imported from Lithuania to the Czech Republic in the spring of 1997 and kept in a quarantine pond. These specimens and those obtained from pond-cultured carp in Russia (Moscow district) were used for detailed morphological studies, including scanning electron microscopy. The results confirm that the valid name of this parasite is Philometroides cyprini (Ishii, 1931), whereas Philometra lusii Vismanis, 1962, Philometra schikhobalowae Belous, 1965, Philometra lusiana Vismanis, 1966 and Philometroides lusiana (Vismanis, 1966) Ivashkin et al., 1971 are its junior synonyms. P. cyprini, the agent of a serious disease of carp, seems to have been originally distributed in east Asia, from where it was introduced into Europe in the early 1960s.
