Abstract
Pseudorhabdosynochus bacchus sp. nov. (Diplectanidae) is described from the gills of the whitespotted grouper Epinephelus coeruleopunctatus collected off New Caledonia, South Pacific, and is the first monogenean reported from this fish. It has a characteristic quadriloculate male organ, with both cone and tube of similar short length (10–12 μm). The morphology of its sclerotised vagina, with two chambers of equal size, differentiates it from all other species of the genus. Other rare Pseudorhabdosynochus species and specimens of an undescribed species of Haliotrema (Ancyrocephalidae) were also found, but in insufficient number to allow description.
Abstract
Pseudorhabdosynochus bacchus sp. nov. (Diplectanidae) est décrit des branchies de la loche à taches blanches Epinephelus coeruleopunctatus pêchée en Nouvelle-Calédonie, Pacifique Sud, et est le premier monogène mentionné de ce poisson. L’espèce a un organe tétraloculé caractéristique, avec un cône et un tube tous deux courts (10–12 μm). La morphologie du vagin sclérifié, avec deux chambres de taille égale, différencie l’espèce de toutes les espèces du genre. D’autres espèces de Pseudorhabdosynochus et des spécimens d’une espèce non décrite d’Haliotrema (Ancyrocephalidae) ont aussi été trouvés, mais en nombre insuffisant pour permettre une description.
