The first record of monogenean parasites of the genus Macrogyrodactylus Malmberg, 1957 on freshwater fish in Senegal is presented. Macrogyrodactylus congolensis Prudhoe, 1957 from the skin and Macrogyrodactylus heterobranchii N’Douba et Lambert, 1999 from the gills of Clarias anguillaris L. were found, representing new host records for these parasites. On Polypterus senegalus Cuvier, three Macrogyrodactylus species were identified, Macrogyrodactylus polypteri Malmberg, 1957, Macrogyrodactylus simentiensis sp. nov. and Macrogyrodactylus sp. M. simentiensis sp. nov. can be readily distinguished from the other Macrogyrodactylus species by the size of its hamuli and the shape of its marginal hook sickles. The marginal hooks on the anterolateral lobes of M. simentiensis differ in size and shape from those on the posterior margin of the haptor. Measurements and drawings of the haptoral sclerites of all five identified species are provided.

Gyrodactylus malalai sp. nov. is described from the fin surface of cichlid fishes Oreochromis niloticus (L.) and Tilapia zillii (Gervais) caught in Lake Turkana (Kenya). The new species morphologically resembles Gyrodactylus nyanzae Paperna, 1973, but can be readily distinguished by the shape of the marginal hook sickles and the size of its hamuli. The sequence data of rDNA spanning partial 18S, internal transcribe spacer 1 and 2 and the 5.8S gene is unique within GenBank. Genetically, as most similar Gyrodactylus ergensi Přikrylová, Matějusová, Musilová et Gelnar, 2009 was found (97.5%). Moreover, a specimen of G. cichlidarum from O. niloticus, and a specimen G. ergensi from Sarotherodon galilaeus (L.) were collected during sampling in Kenya. Likewise, additional sampling of O. niloticus from the Blue Nile in Sudan revealed the presence of the newly described species. These findings represent the first records of gyrodactylids in both African countries.

Nanotrema niokoloensis sp. nov. and a redescription of N. citharini Paperna, 1969 (Monogenea, Dactylogyridae) from the gills of Citharinus citharus citharus (Characiformes, Citharinidae) from Senegal

One previously described and 1 new species of Nanotrema Paperna, 1969 are reported from the gills of Citharinus citharus citharus (Citharinidae) collected from the Niokolo Koba River, Senegal. Nanotrema citharini Paperna, 1969 is redescribed, based on the re-examination of the type specimens and new information obtained from material taken in Senegal (new locality record). Nanotrema niokoloensis sp. nov. is distinguished primarily by possessing a copulatory organ composed of a long thin tube with median portion usually coiled into about 2.5 rings and an accessory piece resembling a braid lying within the rings. Based on the presence of the dorsal anchors modified into paired haptoral spikes, which lack an associated bar, species of Nanotrema phenotypically appear to be related to those of Neotropical Rhinoxenus Kritsky, Boeger et Thatcher, 1988 and Indian Spicocleidus Agrawal, Tripathi et Shukla, 2005.

The infection of metacercariae of Posthodiplostomum cuticola (v. Nordmann, 1832), the agent of black-spot disease, was investigated in 0+juvenile fish from 19 localities in south-east Moravia, Czech Republic. Of the 30 fish species examined, only cyprinids of 12 species were found to be infected. Five species of Leuciscinae, Rutilus rutilus, Leuciscus idus, Scardinius erythrophthalmus, Abramis bjoerkna and Abramis brama, fish with similar behaviour and habitat preference in juvenile period, were the most susceptible fish hosts for P. cuticola metacercariae. Especially high infection parameters were found in intergeneric hybrids of the studied leuciscine species. Environmental conditions were an important factor for parasite infection. The fish from flooded borrow pits, inhabiting lentic water bodies with dense vegetation in the littoral zone, showed high prevalence and abundance of P. cuticola infection contrary to their conspecifics in water reservoirs with steep banks and fish from rivers.
