Heterocotyle whittingtoni n. sp. (Monogenea: Monocotylidae) is described from the gills of the black-spotted whipray Maculabatis toshi (Whitley) (Dasyatidae) collected from Moreton Bay near Dunwich and Peel Island, and from the eastern Gulf of Carpentaria off Weipa, Queensland, Australia. Heterocotyle whittingtoni n. sp. has a single sinuous ridge surmounting the haptoral septa and the male copulatory organ lacks an accessory piece. The new species can be distinguished from the two other Heterocotyle species that have this combination of characters by the distal portion of the male copulatory organ which is slightly flared with uniquely thickened walls and by the morphology of the testis. The identity of the host of H. whittingtoni n. sp. is discussed. We confirm that the host of the monocotylids Dendromonocotyle lasti Chisholm & Whittington, 2005 and Monocotyle caseyae Chisholm & Whittington, 2005 originally identified as "Himantura sp." was M. toshi.
异盘盘虫 Whittingtoni n. sp. (单殖吸虫目：单盘科) 从采集自澳大利亚昆士兰州杜恩威奇和皮尔岛附近的莫尔顿湾以及卡彭塔利亚湾东部威帕的黑斑点长尾魟 Maculabatis toshi (Whitley) (魟科) 的鳃中描述。异盘盘虫 Whittingtoni n. sp. 具有单一的蜿蜒脊，位于固着器隔膜上方，雄性交接器官没有附件。新种可以通过雄性交接器官的远端部分略微向外张开，并且具有独特的增厚壁以及睾丸的形态与具有这一特征的另外两种 Heterocotyle 物种区分开来。讨论了异盘盘虫 Whittingtoni n. sp. 的宿主身份。我们确认了原本被鉴定为“Himantura sp.”的单殖吸虫目Dendromonocotyle lasti Chisholm & Whittington, 2005 和 Monocotyle caseyae Chisholm & Whittington, 2005 的宿主是 M. toshi。
