摘要
Heterosentis hirsutus n. sp. is described from Cnidoglanis macrocephalo (Siluriformes: Plotosidae) from the Swan Estuary, Western Australia. It is distinguished by having 14 longitudinal rows of 6-7 hooks per row on the proboscis, a trunk armed anteriorly and posteriorly (=genital spines) with minute spines and lemnisci that may extend to the poster;or margin of the proboscis receptacle The new species also has prominent fragmented nuclei in its trunk well. New information is given for Heterosentis plotosi Yamoguti, 1935 from Plotosus lineatus (Siluriformes: Plotosidae) and H. poraplagusiarum (Nickol, 1972) Amin, 1985 from Paraplogusia guttata (Pleuronectiformes: Cynoglossidoe), both from Queensland. A key to the species of Heterosentis Van Cleave, 1931 is provided. The Arhythmacanthidae subfamilies are reviewed: there is little utility in the recognition of these taxa because of the small number of genera involved and the validity/ of the characters on which they ore based is in doubt, particularly whether trunk spines are present or absent. Only Acanthocephaloides Meyer, 1932, Breizocanthus Golvon, 1969, Euzetocanthus Golvan & Houin, 1964, Heterosentis, Hypoechinorhynchus Yamaguti, 1939 and Paracanthocepholoides Golvan, 1969 of the Arhythmacanthidae are considered valid. A key to these genera is provided. The monotypic genus Neocanthocepholoides Cable & Quick, 1954 is considered a new synonym of Acanthocephaloides thus creating Acanthocephaloides spinicaudatus (Cable & Quick, 1954) n. comb. Arhythmocanthus Yamaguti, 1935 is maintained as a synonym of Heterosentis because the distinction between two and three hook types is made equivocal when the transition between the opical and subapical hooks is gradual.
