Hung. 8. 63-70. 1975. ABSTRACT. On the ground of zoogeographical considerations the authors put forward the wiev that K. sinensis of the carp was introduced to Hungary from the Trans-Carpathian area by natural route through the river Tisza. Morphological studies of the carp parasites C. fimbriceps and K. sinensis by histological methods resulted in certain modifications of the original descriptions of K.sinensis. Six species of the family Caryophyllaeidae (Caryophyllaeus brachycollis Janiszewska, 1951, C. fimbriceps Annenkova-Chlopina, 1919, C.laticeps /Pallas, 1787/, Paracaryophyllaeus dubininae Kulakovskaya, 1961, Biacetabulum appendiculatum (Szidat, 1937/, Ca~- ryophyllaeides fennica /Schneider, 1902/) were formerly known to occur in Hungary (EDELENYI, 1967; ERGENS et al., 1974; MOLNÁR, 1970; MATSKÁSI et al. , 1-971). The occurrence of a seventh species, Khawia sinensis Hsü, 1935, has recently been reported by MOLNÁR and BUZA (1975). According to Russian authors (KULAKOVSKAYA and KROTAS, 1961; IVASIK et al., 1968), among the Caryophyllaeidae species found in Europe, two have been of economic importance, K. sinensis and C. fimbriceps . The latter has been erroneously regarded as synonymus with C. laticeps by several authors. KULAKOVSKAYA and KROTAS hold the view that K. sinensis , which had been introduced with amur carps imported from the Far East, is gradually superseding C. fimbriceps, which had formerly been very widely spread in Europe. The presence of K. sinensis in the European territory of the Soviet Union was reported first by KULAKOVSKAYA and KROTAS (1961) and its spread beyond the Carpathian mountains by IVASIK et al. (1970). PRIBYSLAVSKY et al. (1965) in Czechoslovakia found a Khawia specimen, which they regarded as K. sinensis but on the basis of epizootological considerations characterized it as an indigenous parasite for Europe. The anatomy of various Caryophyllaeidae species has been extensively studied. WILL (1893) dealt in great detail with C. laticeps ( C. mutabilis) , CALETINE and ULMER (1961) with K. iowensis and MACKIEWITZ (1972) elaborated a parasitological rewiew of the entire group. However, the anatomical details of the two species parasitic in carps in Hungary ( C. fimbriceps. K. sinensis ) were only known from the original descriptions (ANNENKOVA-CHLOPINA, 1919; HSÜ, 1935) and from later studies of KULAKOVSKAYA and KROTAS (1961). The present studies were carried out to obtain more information on the morphological details of these two species of economically important carp parasites and to assess the frequency of occurrence of K. sinensis in the home carp populations.
