Abstract

ORIG EN

V originále

Parasitic nematodes referable to Procamallanus (Procamallanus) laeviconchus (Wedl, 1861) were obtained from stomachs of various African freshwater fishes from the Mare Simenti in the Niokolo Koba National Park, East Senegal and from the Lake Turkana, North Kenya. Specimens of P. laeviconchus were found mainly in catfishes from families Mochokidae, Clariidae and partially also in Bagridae (Siluriformes) and in fish from family Citharinidae (Characiformes). For morphological study of important differentiation features of nematodes, scanning electron microscopy (SEM) and light microscopy (Nomarski differential contrast) were used. P. laeviconchus is characterized mainly by the presence of almost rounded mouth openning, provided with peribuccal flange forming 6 bifid lobes. Deirids are very small and simple. Important morphological differences between specimens from different hosts were found in our material. This suggest that P. laeviconchus is a species complex, including at least three species.
