    Notes: Summary The variability of monogenean gill ectoparasite species richness in 19 West African cyprinid species was analyzed using the following seven predictor variables: host size, number of drainage basins, number of sympatric cyprinid species, host diversity, association with mainland forest, host ecology, and monogenean biological labelling. The size of the host species accounted for 77% of the variation in the number of parasite species per host, and host ecology an additional 8%. Together the effects of host size and host ecology accounted for 85% of the variation in monogenean species richness. This study shows that the deciding factors for explaining monogenean species richness in West African cyprinid fishes are host species size and host ecology. These results were compared with main factors responsible for parasite species richness in fish communities. Other possible explanations of monogenean community structure in west African cyprinids are discussed.

    New species of the Monocotylidae (Monogenea) from the stingray Dasyatis tortonesi Capapé (Euselachii, Dasyatidae) off the Tunisian coast, with comments on host-specificity and the specific identities of Mediterranean stingrays (2000)

    Notes: Abstract Heterocotyle capapei n. sp. and Thaumatocotyle tunisiensis n. sp. are described from the gills and the nasal cavity, respectively, of Dasyatis tortonesicollected from the Tunisian coast. H. capapei is distinguished from other species in the genus by the morphology of the penis, which is conical and has a long narrow distal point. T. tunisiensis differs from all known species of Thaumatocotyle by the shape and size of the penis. The host Dasyatis tortonesi has long been confused with D. pastinaca. Our study shows that their monogeneans are oioxenic, suggesting that D. pastinaca and D. tortonesi are distinct species. These results suggest that the monogenean parasite fauna could be used as a diagnostic tool for species identification: these parasites may, therefore, represent good biological indicators. The host-specificity of the Heterocotylinae and Merizocotylinae is discussed.

    A new type of haptor in mesoparasitic monogeneans of the genus Enterogyrus Paperna, 1963, with a description of Enterogyrus foratus n. sp. and E. coronatus n. sp, stomach parasites of cichlids in West Africa (1991)

    Notes: Abstract Descriptions are given of Enterogyrus foratus n. sp., collected from the stomach of Sarotherodon melanotheron (Osteichtyes, Cichlidae) in Senegal and the Ivory Coast, and E. coronatus n. sp. from the stomach of Tilapia guineensis (Osteichtyes, Cichlidae) in the Ivory Coast. The two new species differ from almost all other congeneric species mainly with regard to the novel shape of the haptor. This haptor comprises two segments: an elongated posterior peduncular segment, which deeply penetrates the stomach wall, and a bulbous anterior segment. The posterior segment bears two pairs of hamuli (dorsal and ventral), a transverse V-shaped ventral bar and ventral hooklets I and II. The anterior segment has hooklets III and IV (dorsal) and V to VII (ventral) arranged in an equatorial circle. These two species possess the spiral cirrus characteristic of the genus Enterogyrus, but differ with respect to each other and to other members of the genus by the nature of the spirality of the cirrus.

    Notes: Abstract A study of gill parasites of Tilapia guineensis (Bleeker, 1862) (Cichlidae) from different locations in West Africa (Senegal, Guinea, the Ivory Coast and the Congo) revealed the presence of twelve species of Cichlidogyrus Paperna, 1960 (Monogenea). Six have been recorded previously from T. zillii (Gervais, 1848) or Tristamella simonis (Günther, 1864) and six are considered new species: C. agnesi n. sp., C. bilongi n. sp., C. gallus n. sp., C. flexicolpos n. sp., C. louipaysani n. sp. and C. vexus n. sp. In the first three species cited, we report the presence of an auxiliary plate in the male copulatory complex which is characteristic of the species C. aegypticus Ergens, 1981, a parasite of Tilapia zillii.

    Notes: Abstract We describe a new ancyrocephalid monogenean, Haliotrema cupensis n. sp., from a marine gobiid, Gobius cobitis (Pallas) from the Mediterranean Sea. This species differs from the other members of the genus by the morphology of the penis and accessory piece, the haptoral ornamentation and by possessing a larger testis. This is the first report of an ancyrocephalid on a marine gobiid and of a Haliotrema species in the Mediterranean Sea.

    Notes: Abstract Descriptions of three new species of Monogenea are presented: Cichlidogyrus berrebii n. sp., C. pouyaudi n. sp. and C. kothiasi n. sp., all gill parasites of Tylochromis jentinki (Cichlidae) in West Africa (Ivory Coast and Guinea). These new species are considered primitive because of the morphology of the dorsal transverse bar of the haptor, but this is not considered sufficient to warrant their exclusion from the genus Cichlidogyrus.
