“…Sporocysts and metacercariae interpreted as unidentified species of Proctoeces have been reported from oysters (Saccostrea Dollfus & Dautzenberg spp.) from Queensland and New South Wales [9,23]. Here we combine morphological and molecular analyses to identify the richness of species of Proctoeces infecting teleosts from Queensland waters and explore host-specificity.…”

“…As sexually mature adults, species of the genus have been reported from many families of teleost fishes globally; however, the genus is strongly concentrated in two families, the Sparidae and Labridae [1][2][3]. Unusually for the Fellodistomidae, species of Proctoeces may also develop into sexually mature adults in the second [4][5][6][7] and even the first intermediate host [2,[8][9][10]; in some instances, the definitive host has been apparently completely excluded from the life-cycle [11] and several species have been described solely on the basis of infections from invertebrates [5,7,12,13].…”

Species of Proctoeces Odhner, 1911 (Trematoda: Fellodistomidae) have been reported from a wide range of marine animals globally. Members of the genus tend to lack strongly distinguishing morphological features for diagnosis, making identification difficult and the true number of species in the genus contentious. Combined morphological and molecular analyses were used to characterise three species of Proctoeces from Moreton Bay and the southern Great Barrier Reef. Data for two ribosomal regions and one mitochondrial region were generated for specimens collected from Australia. Three unique 18S-genotypes were identified which corresponded to subtle, but reliable, morphological differences. Two species of Proctoeces were identified from fishes of Moreton Bay, Proctoeces insolitus (Nicoll, 1915) Yamaguti, 1953 and P. major Yamaguti, 1934, and a third, P. choerodoni n. sp. from off Heron Island on the southern Great Barrier Reef. Phylogenetic analyses of partial 18S and partial 28S rDNA indicated that these three species differ from the four species reported outside of Australia for which sequence data are available. Phylogenetically, Proctoeces proved to be a reliable concept, with all species of Proctoeces that have been characterised genetically forming a well-supported clade in all analyses. Dramatically different patterns of host-specificity were identified for each of the three Australian species; P. insolitus apparently infects a single species of fish, P. choerodoni n. sp. infects multiple species of a single genus of fish, and P. major infects multiple species of two teleost orders.

“…Although numerous species of this family parasitize many marine pelecypods as primary hosts and secondary hosts worldwide (Lauckner, 1983;Wolf et al, 1987), Proctoeces maculatus, which infects blue mussels as well as other mollusca, has the greatest economic impact. Thus, this section presents information only on P. maculatus.…”
