Pseudorhabdosynochus bacchus sp nov (Monogenea, Diplectanidae) fromEpinephelus coeruleopunctatus (Perciformes, Serranidae) off New Caledonia
Pseudorhabdosynochus bacchus sp. nov. (Diplectanidae) is described from thegills of the whitespotted grouper Epinephelus coeruleopunctatus collected off New Caledonia, SouthPacific, and is the first monogenean reported from this fish. It has a characteristic quadriloculatemale organ, with both cone and tube of similar short length (10-12 mu m). The morphology of itssclerotised vagina, with two chambers of equal size, differentiates it from all other species of thegenus. Other rare Pseudorhabdosynochus species and specimens of an undescribed species ofHaliotrema (Ancyrocephalidae) were also found, but in insufficient number to allow description.
