The monotypic genus Diploheteocotyla Yamaguti, 1965, parasitic on the gills of a dasyatidid ray collected off Hawaii, is synonymized with Heterocotyle Scott, 1904. Its type species, D. dasyatis Yamaguti, 1965, is redescribed, illustrated, and transferred to Heterocotyle as H. dasyatis (Yamaguti, 1965) n. comb. Heterocotyle dasyatis is distinguished from the 9 known species of the genus by the morphology of the male copulatory organ, by the accessory piece, which is composed of 10 sclerotized strands, and by the presence of a complex sclerite in the proximal portion of the vagina. The apparent presence of spermatophores is recorded for the first time in this genus.
单型属双盘异杯吸虫属（Diploheteocotyla），由Yamaguti于1965年建立，寄生于从夏威夷海域采集的一种鲼形目鳐鱼的鳃上，现被认定为与1904年的异杯吸虫属（Heterocotyle）同义。对其模式种双盘异杯吸虫（D. dasyatis）Yamaguti，1965进行了重新描述、绘图，并作为异杯吸虫属的新组合种达斯亚蒂异杯吸虫（H. dasyatis (Yamaguti, 1965)）进行了转移。达斯亚蒂异杯吸虫与该属已知的9个物种的区别在于雄性交配器官的形态、由10条硬化丝组成的附属片以及阴道近端存在一个复杂的硬化体。首次记录到该属明显存在精荚。
