Abstract 

Examination of 64 elasmobranchs comprising 13 species from Moreton Bay yielded 13 identifiable species of cestodes of the order Trypanorhyncha Diesling, 1863. Two new species, Dollfusiella armata sp. nov. from Maculabatis toshi (Whitley, 1939) and M. cf. astra Last, Manjaji- Matsumoto and Pogonoski, 2008, and Dollfusiella pilosa sp. nov. from Aetobatus ocellatus (Kuhl, 1823) are described. Prochristianella odonoghuei Beveridge, 1990 becomes a junior synonym of Prochristianella butlerae Beveridge, 1990 based on identical strobilar and tentacular morphologies. Prochristianella omunae Beveridge and Justine, 2010 is reported from Australia for the first time, where it was recovered from the type host Neotrygon trigonoides (Castelnau, 1873). Additional new host records are included as well as extensions of known geographical distributions to now include south-eastern Queensland. Metacestodes were recovered from the digestive glands of yabbies, Trypaea australis (Dana, 1852), representing an undescribed species of Dollfusiella. Adults of this species were found in the spiral valves of N. trigonoides and Ae. ocellatus. Six species of metacestodes of trypanorhynch cestodes were recovered from the digestive glands of pistol shrimps, Alpheus spp. (A. richardsoni Yaldwyn, 1971 and A. papillosus Banner & Banner, 1982). Of these, three were identified as Parachristianella monomegacantha Kruse, 1959, Prochristianella aciculata Beveridge and Justine, 2010 and Zygorhynchus robertsoni Beveridge and Campbell, 1988, the adults of all three species being originally reported from batoids. Two undescribed species of Dollfusiella and undescribed species of Parachristianella and Zygorhynchus were also recovered from alpheid shrimps; definitive hosts were identified for each species, but the material available was insufficient to allow formal descriptions.
