| Abstract: | Two new species of hemiurine hemiurid are described from Spratelloides robustus off Woodman Point in southern Western Australia. Hemiurus lignator n. sp. differs from its congeners by a combination of similar-sized suckers, long sinus-sac, tandem testes, relatively elongate shape and unthickened seminal vesicle wall. Parahemiurus xylokopos n. sp. differs from its congeners in a combination of its squat form, its distinctly lobed vitellarium and the proximity of the gonads to the ventral sucker. P. merus (Linton, 1910) is reported from Acanthopagrus australis, Pomatomus saltatrix and Trachinotus coppingeri off northern New South Wales, Caranx sexfasciatus, Scorpis lineolata, Siganus nebulosus, Thunnus tonggol and T. coppingeri off southern Queensland, Cephalopholis boenak and Euthynnus affinis off Heron Island, southern Great Barrier Reef, P. saltatrix off southern Western Australia and Priacanthus hamrur off New Caledonia. |
