Faustulid trematodes (Digenea) from marine fishes of Australia

Twelve species of faustulid trematode are described or redescribed from Aus tralian marine fishes. Bacciger lesteri Bray, 1982 and B. sprenti Bray, 198 2 are redescribed from Selenotoca multifasciata from Moreton Bay. It is sug gested that the original host record for these species, Mugil sp., was inco rrect. The genera Discogastroides, Odontocotyle and Pseudodiscogasteroides are synonymised with Paradiscogaster. The new combinations Paradiscogaster arabi (Hafeezullah & Siddiqi, 1970), P. hainanensis (Shen, 1970), P. indicu s (Srivastava, 1939), P. macrostomus (Shimazu & Kamegai, 1990), P. ostracii (Yamaguti, 1934) and P. pritchardae (Gupta & Ahmad, 1978) are proposed. Di scogasteroides hawaiensis Hanson, 1955 is synonymised with P. ostracii. P. macrostomus and P. ostracii are redescribed from Ostracion meleagris and O. cubicus from the Great Barrier Reef. P. farooqii Hafeezullah & Siddiqi, 19 70 is redescribed from Monodactylus argenteus from Moreton Bay. The followi ng new species are described: P. machidai n. sp. from Pomacanthus semicircu latus and P. sexstriatus from the Great Barrier Reef, P. dweorg n. sp. from Meuschenia galii, P. lobomyzon n. sp. from Tilodon sexfasciatus and P. hab ilis n. sp. from Pelates octolineatus, all from Western Australia. Antorchi s pomacanthi (Hafeezullah & Siddiqi, 1970) Machida, 1975 is redescribed fro m Pomacanthus semicirculatus and P. sexstriatus from the Great Barrier Reef . The new combination Antorchis intermedius (Madhavi, 1975) is proposed for Parantorchis intermedius. Parayamagutia ostracionis is redescribed from O. cubicus from the Great Barrier Reef. Trigonocryptus conus is redescribed f rom Arothron hispidus from South-east Queensland and from A. nigropunctatus from the Great Barrier Reef. The new combination Trigonocryptus australien sis (Kurochkin, 1970) is proposed for Pseudodiscogasteroides australiensis. The Echinobrevicecinae is reduced to synonymy with the Faustulidae.
