Heterobucephalopsine and prosorhynchine trematodes (Digenea: Bucephalidae) from teleost fishes of Moreton Bay, Queensland, Australia, with the description of two new species.

Abstract：

:Eight species of the trematode family Bucephalidae Poche, 1907 are reported from teleost fishes in Moreton Bay, Queensland, Australia. Heterobucephalopsis yongi n. sp. is described from Gymnothorax eurostus (Muraenidae); the new form is distinguished from its congeners in the possession of a tiny cirrus-sac relative to body length, the length of the caecum, the position of the mouth and pharynx, and the position of the testes and ovary. Two known species of Dollfustrema Eckmann, 1934, D. durum Nolan, Curran, Miller, Cutmore, Cantacessi & Cribb, 2015 and D. gibsoni Nolan & Cribb, 2010, are reported from Gymnothorax pseudothyrsoideus (Bleeker) (Muraenidae); although both species were described from Australian waters, this represents the first reports from Moreton Bay and G. pseudothyrsoideus. Four species of Prosorhynchus Odhner, 1905 are reported, including one new, P. brayi n. sp., which is described from Epinephelus coioides (Hamilton) (Serranidae); P. brayi n. sp. is distinguished from its congeners in the possession of vitelline follicles in a confluent arc distinctly posterior to a conical rhynchus, uterine coils that do not extend anterior to the vitelline arc, contiguous testes, a cirrus-sac that reaches anteriorly to at least the level of the posterior testis and a short excretory vesicle. Three known species of Prosorhynchus are reported from Australia, for the first time: P. luzonicus Velasquez, 1959 and P. maternus Bray & Justine, 2006 from E. coioides and Prosorhynchus platycephali (Yamaguti, 1934) Srivastava, 1938 from Ambiserrula jugosa (McCulloch) and Inegocia japonica (Cuvier) (Platycephalidae). Skrjabiniella Issaitschikow, 1928 is re-recognised for new specimens of Skrjabiniella uniporus (Ozaki, 1924) n. comb. collected from Conger cinereus Rüppell (Congridae); three additional species of Prosorhynchus are considered members of this genus, two of which are synonymised with S. uniporus.
