Six new species of Cichlidogyrus Paperna, 1960 (Platyhelminthes: Monogenea) from the gills of cichlids (Teleostei: Cichliformes) from the Lomami River Basin (DRC: Middle Congo).

摘要: Monogenea van Beneden, 1858 is a group of parasitic flatworms, commonly found infecting bony fish. Several genera, such as Cichlidogyrus Paperna, 1960, are reported to include potential pathogenic species that can negatively impact aquaculture fish stocks. They switch from introduced native and vice versa. In Africa (and all over the world), belonging Cichlidae often kept in represent major source food. Thus, research on biodiversity occurrence monogenean these importance for conservation. The present study survey diversity south Democratic Republic Congo (DRC) three cichlid species: Orthochromis sp. ‘Lomami’, Serranochromis cf. macrocephalus, Tilapia sparrmanii Smith, 1840. Specimens were isolated gills mounted glass slides with Hoyer’s medium. genital haptoral hard parts measured drawn using interference contrast. total, six found, new science: C. bulbophallus n. pseudozambezensis S. flagellum lobus T. sparrmanii, ranula macrocephalus maeander ‘Lomami’ sparrmanii. first four considered be strict specialists, an intermediate generalist generalist. These parasite show morphological similarities Lower Guinea Zambezi ichthyofaunal provinces, which might explained by past river capture events between systems Province both regions. harbour respectively two Cichlidogyrus, described this study. seven species, results highlight genus Basin.
