Abstract
Survey on dactylogyrids parasitizing catfishes was carried out in White Nile and Blue Nile, Sudan, in 2014. Dactylogyrids were isolated from 12 siluriform species, belonging to six families (Bagridae, Clariidae, Claroteidae, Malapteruridae, Mochokidae and Schilbeidae). Dactylogyrid species of the following genera were found: Bagrobdella, Protoancylodiscoides, Quadriacanthus, Schilbetrema and Synodontella. The taxonomic evaluation has been made on the basis of morphology, and also the partial 28S rDNA (LSU) sequences have been analysed for a purpose of species identification and evaluation of the phylogenetic positions of representatives of dactylogyrids infecting African catfishes wihin the family Dactylogyridae. Detailed taxonomic evaluation of monogeneans belonging to Quadriacanthus revealed the presence of five species (one new) from the gills of 4 species of catfishes: Quadriacanthus bagrae Paperna, 1979 from Bagrus bajad and Bagrus docmac (Bagridae); Quadriacanthus aegypticus El-Naggar & Serag, 1986, Quadriacanthus clariadis Paperna, 1961, and Quadriacanthus numidus Kritsky & Kulo, 1988 from Clarias gariepinus (Clariidae); and Quadriacanthus mandibularis n. sp. from Heterobranchus bidorsalis (Clariidae). The new species resembles Quadriacanthus thysi N’Douba, Lambert & Euzet, 1999, but clearly differs from this species by having a male copulatory organ with spoon-like base, broad copulatory tube with subterminal flap, and basally articulated accessory piece with constricted medial part and hook-shaped terminal portion.
