Microcotylids have rarely been reported along the South African coast, even though the Microcotylidae is one of the dominant polyopisthocotylan families. The present study focused on elucidating the parasite diversity of the Cape white seabream, Diplodus capensis (Smith), from various localities along the South African coast. By combining molecular and morphological techniques, two previously undescribed species of the Microcotylidae were identified. Atriaster ibamba n. sp. primarily differs from its congeners by the number and size of the hooks surrounding the genital atrium. Polylabris dassie n. sp. has a single vagina and is unique to most others of this genus by having a smaller male copulatory organ, and by the shape of this organ. This is the first report of species of Atriaster from South Africa, as well as the first report of any polyopisthocotylan from D. capensis. The present study also contributes the first genetic sequences of marine microcotylids from South Africa.
Résumé
Les Microcotylidae ont rarement été signalés le long des côtes sud-africaines, bien cette famille soit l’une des plus nombreuses des Polyopisthocotyla. La présente étude s’est attachée à élucider la diversité parasitaire du sar commun du Cap, Diplodus capensis (Smith) dans diverses localités de la côte sud-africaine. En combinant des techniques moléculaires et morphologiques, deux espèces de Microcotylidae jusque-là non décrites ont été identifiées. Atriaster ibamba n. sp. se distingue principalement de ses congénères par le nombre et la taille des crochets entourant l’atrium génital. Polylabris dassie n. sp. possède un seul vagin et se distingue de la plupart des autres espèces de ce genre par son organe copulateur mâle plus petit et par la forme de cet organe. Il s’agit de la première mention d’une espèce d’Atriaster en Afrique du Sud, ainsi que de la première mention d’un Polyopisthocotyla chez D. capensis. Cette étude fournit également les premières séquences génétiques de Microcotylidae marins d’Afrique du Sud.
