Gills of carangid fishes in Australian waters are dominated by a diversity of polyopisthocotylean monogeneans. This study updates current knowledge of polyopisthocotyleans from carangid hosts in waters along the Queensland coast of Australia and also off New Caledonia. The discovery of Protomicrocotyle celebesensis Yamaguti, 1953 is the first record for the genus in Australian waters and represents a new geographic location for the species, extending its distribution from Sulawesi, Indonesia and Hawaii to Australia. Furthermore, Caranx ignobilis and Carangoides fulvoguttatus are reported as new host records for P. celebesensis. Carangoides gymnostethus is recorded as a new host for Heteromicrocotyla australiensis Rohde, 1977 from a new geographic location, namely Lizard Island, Queensland. Heteromicrocotyloides mirabilis Rohde, 1977 is reported from the gills of C. fulvoguttatus off Lizard Island, Queensland representing a new geographic record. Heteromicrocotyloides megaspinosus sp. nov. is described from the gills of C. fulvoguttatus from Lizard Island, Queensland and New Caledonia. The new species is distinguished from H. mirabilis by the larger number and size of spines in the male genital corona. Gonoplasius carangis was collected from Pseudocaranx dentex at Heron Island, Queensland. Gonoplasius longirostri is synonymised with G. carangis due to overlap in measurements and similar morphology. The number of ‘dorsal pits’ in this taxon may not be a useful character because they can be cryptic and hard to see. Most hosts from which these two Gonoplasius species have been collected previously have been synonymised as Pseudocaranx dentex except Caranx ascensionis which is now considered to be C. lugubris. Our report of G. carangis from P. dentex at Heron Island, Queensland is a new geographic record.

Les branchies des poissons Carangidae des eaux Australiennes sont dominées par une variété de monogènes Polyopisthocotylea. Cette étude met à jour notre connaissance actuelle des Polyopisthocotylea des Carangidae des eaux des côtes du Queensland (Australie) et aussi de Nouvelle-Calédonie. La découverte de Protomicrocotyle celebesensis Yamaguti, 1953 est la première mention du genre dans les eaux Australiennes et représente une nouvelle mention géographique pour l’espèce, étendant sa distribution depuis le Sulawesi, l’Indonésie et Hawaii jusqu’à l’Australie. De plus, Caranx ignobilis et Carangoides fulvoguttatus sont rapportés comme nouveaux hôtes pour P. celebesensis. Carangoides gymnostethus est rapporté comme nouvel hôte pour Heteromicrocotyla australiensis Rohde, 1977, d’une nouvelle localité géographique, Lizard Island, Queensland. Heteromicrocotyloides mirabilis Rohde, 1977 est rapporté des branchies de C. fulvoguttatus de Lizard Island, Queensland, comme nouvelle mention géographique. Heteromicrocotyloides megaspinosus sp. nov. est décrit des branchies de C. fulvoguttatus de Lizard Island, Queensland et de Nouvelle-Calédonie. La nouvelle espèce est distinguée de H. mirabilis par des épines plus nombreuses et plus longues dans la couronne génitale. Gonoplasius carangis a été collecté de Pseudocaranx dentex à Heron Island, Queensland. Gonoplasius longirostri est synonymisé avec G. carangis sur la base de recouvrements des mensurations et d’une morphologie similaire. Le nombre de “puits dorsaux” dans ce taxon n’est probablement pas un caractère utile car ces structures peuvent être cryptiques et difficiles à voir. La plupart des hôtes chez lesquels ces deux espèces de Gonoplasius ont été précédemment collectées ont été synonymisés avec Pseudocaranx dentex, à part Caranx ascensionis qui est maintenant considéré comme étant C. lugubris. Notre mention de G. carangis chez P. dentex à Heron Island, Queensland, est une nouvelle mention géographique.
