({A}ncyrocephalidae) and {A}llobenedenia sp. ({C}apsalidae), both undescribed, were also found on large fish. {P}seudorhabdosynochus duitoe {J}ustine, 2007 and {P}. huitoe {J}ustine, 2007, were collected in very small numbers, mainly in young (345-500 mm) fish; the type-host of these two species is the highfin grouper, {E}. maculatus, and their occurrence on {E}. cyanopodus was considered accidental and due to habitat overlap between the young speckled blue groupers and adult highfin groupers. {I}t is hypothesized that the speckled blue groupers are infested by their own, strictly specific monogeneans, only when they encounter older members of their species during spawning aggregations. {S}pawning aggregations thus play a key role in infestation of coral reef fish by their monoxenic parasites such as monogeneans. {L}ists are given for other parasites of the speckled blue grouper, including digeneans, cestodes, nematodes, isopods and copepods, with new records from {N}ew {C}aledonia: 41 species of parasites are recorded.}, keywords = {}, booktitle = {}, journal = {{Z}ootaxa}, volume = {(1695)}, numero = {}, pages = {1--44}, ISSN = {1175-5326}, year = {2008}, URL = {https://www.documentation.ird.fr/hor/{PAR}00002153}, }
