DIPLOPROCTODAEINAE (DIGENEA, LEPOCREADIIDAE) FROM THE COASTAL FISHES OF QUEENSLAND, AUSTRALIA, WITH A REVIEW OF THE SUBFAMILY

The subfamily Diploproctodaeinae is reviewed and a key to the five rec ognized genera is given. Diploproctodaeum is redefined and a key to sp ecies given and Caecobiporum is considered a synonym. Diploproctodaeum yosogi n. sp. from Paramonacanthus japonicus, Moreton Bay, is disting uished by its small cirrus-sac and short oesophagus. Diploproctodaeum momoaafata n. sp. from Ostracion cubicus and O. meleagris, Heron Is., is characterized by the number of ovarian follicles. Diploproctodaeum macracetabulum is redescribed from Abalistes stellaris, Heron Is. Dipl oproctodaeum sp. is described from Cantheschenia grandisquamis, Heron Is. New combinations are made for D. bombayensis (originally Bianium), D. rameshwarensis (originally Bianium) and D. rutellum (originally Ca ecobiporum). The genus Diplocreadium is redefined and a key to species given. D. tsontso n. sp. from Balistoides conspicillum, Heron Is., is distinguished by its dorso-ventrally placed testes and by its vitelli ne distribution. Diplocreadium tangaloomaensis n. sp. from Paramonacan thus japonicus, Moreton Bay, is distinguished by its tandem testes and its vitelline distribution. The genus Diploproctodaeoides is redefine d and D. longipygum is redescribed from Abalistes stellaris, Heron Is. The genus Bianium is redefined and a key to species is given; Diplopo rus, Diploporetta, Amarocotyle and Anterovitellosum are considered syn onyms of Bianium. Bianium rewa n. sp. from Cantherhines pardalis, Hero n Is. and Ryukyu Is., Japan, is distinguished by its trilobed ovary. A new combination is made for B. indicum (originally Anterovitellosum), The genus Diploproctia is redefined. The character evolution, host-sp ecificity and zoogeography of the subfamily are discussed.
