Heliocotyle ewingi sp. n. (Monogenea: Monocotylidae) is described from the gills of Myliobatis australis Macleay, 1881 (Myliobatididae) collected from Norfolk Bay near Hobart, Tasmania, Australia. Heliocotyle ewingi can be distinguished readily from the only other species in the genus, Heliocotyle kartasi Neifar, Euzet et Ben Hassine, 1999, by the presence of a single pseudoseptum on each of the peripheral loculi except the posteriormost, eyespots and by the morphology of the male copulatory organ which is a short, straight sclerotised tube which lacks a sclerotised accessory piece. The generic diagnosis is revised to accommodate the new species and the anterior glands are discussed.
新种尤氏太阳吸虫（Heliocotyle ewingi sp. n.，单殖吸虫纲：单杯科）采自澳大利亚塔斯马尼亚州霍巴特附近诺福克湾的澳大利亚鲼（Myliobatis australis Macleay，1881，鲼科）鳃部。尤氏太阳吸虫可轻易与该属的另一个物种——卡尔塔斯太阳吸虫（Heliocotyle kartasi Neifar、Euzet和Ben Hassine，1999）区分开来，其除最后端的外周小室各有一个假隔膜、具眼点，且雄性交配器官形态为短而直的硬化管，无硬化附属片。修订了属的诊断以容纳新物种，并对前腺进行了讨论。
