Trypanorhynch metacestodes were examined from teleosts from coral reefs in eastern Australia and from New Caledonia. From over 12,000 fishes examined, 33 named species of trypanorhynchs were recovered as well as three species of tentacularioids which are described but not named. Host-parasite and parasite-host lists are provided, including more than 100 new host records. Lacistorhynchoid and tentacularioid taxa predominated with fewer otobothrioid and gymnorhynchoids. Five species, Callitetrarhynchus gracilis, Floriceps minacanthus, Pseudotobothrium dipsacum, Pseudolacistorhynchus heroniensis and Ps. shipleyi, were particularly common and exhibited low host specificity. Limited data suggested a higher diversity of larval trypanorhynchs in larger piscivorous fish families. Several fish families surveyed extensively (Blenniidae, Chaetodontidae, Gobiidae, Kyphosidae and Scaridae) yielded no trypanorhynch larvae. The overall similarity between the fauna of the Great Barrier Reef and New Caledonia was 45%. Where available, information on the adult stages in elasmobranchs has been included.
Résumé
Les métacestodes de Trypanorhynques de téléostéens des récifs coralliens de l’est de l’Australie et de Nouvelle-Calédonie ont été examinés. À partir de plus de 12000 poissons examinés, 33 espèces nommées de Trypanorhynques ont été collectées ainsi que trois espèces de Tentacularioidea qui sont décrites mais non nommées. Des listes hôtes-parasites et parasites-hôtes sont fournies, et incluent plus de 100 nouvelles mentions d’hôtes. Les taxa appartenant aux Lacistorhynchoidea et Tentacularioidea prédominaient et les Otobothrioidea et Gymnorhynchoidea étaient moins nombreux. Cinq espèces, Callitetrarhynchus gracilis, Floriceps minacanthus, Pseudotobothrium dipsacum, Pseudolacistorhynchus heroniensis et Ps. shipleyi étaient particulièrement fréquentes et montraient une faible spécificité d’hôte. Des données limitées suggèrent une plus grande diversité de Trypanorhynques larvaires dans les familles de poissons piscivores de grande taille. Plusieurs familles de poissons étudiées intensivement (Blenniidae, Chaetodontidae, Gobiidae, Kyphosidae et Scaridae) n’avaient pas de larves de Trypanorhynques. La similitude globale entre les faunes de la Grande Barrière de Corail et de la Nouvelle-Calédonie était de 45 %. Des informations sur les stades adultes chez des élasmobranches ont été incluses quand disponibles.
