A new cestode, Macrobothridium sinensis n. sp., is described from the spiral intestine of Platyrhina sinensis from coast of Xiamen, China. It is the first record of the order Diphyllidea in China. The new species can be distinguished from the 3 previously described species of Macrobothridium by the testes number (16-24 vs. 29-37, 27-46, and 5-6, in M. rhynchobati, M. euterpes, and M. syrtensis, respectively) and a single-row arrangement of testes; M. sinensis is most similar to M. euterpes in strobila length (1.77-6.23 vs. 2-4.5 mm) and number of segments (6-8 vs. 5-9). In addition, M. sinensis differs from M. rhynchobati and M. syrtensis in the strobila length, ovary shape, and number of apical hooks. The uterine pore is the first described in the Diphyllidea; thus, the present uterine pore can now be used to distinguish Macrobothridium from Echinobothrium and Ditrachybothridium in the Diphyllidae.
在中国厦门海岸的中华扁鲨的螺旋肠中发现了一种新的绦虫，中华巨槽绦虫（Macrobothridium sinensis n. sp.）。这是双叶目在中国的首次记录。新物种可通过睾丸数量（中华吻槽绦虫（M. rhynchobati）、尤氏巨槽绦虫（M. euterpes）和叙利亚巨槽绦虫（M. syrtensis）分别为29 - 37、27 - 46和5 - 6个，而中华巨槽绦虫为16 - 24个）以及睾丸的单列排列与之前描述的3种巨槽绦虫区分开来；中华巨槽绦虫在节片长度（1.77 - 6.23毫米对2 - 4.5毫米）和节片数量（6 - 8个对5 - 9个）方面与尤氏巨槽绦虫最为相似。此外，中华巨槽绦虫在节片长度、卵巢形状和顶钩数量方面与中华吻槽绦虫和叙利亚巨槽绦虫不同。子宫孔是双叶目中首次描述的；因此，目前的子宫孔现在可用于在双叶科中将巨槽绦虫与棘槽绦虫属（Echinobothrium）和双槽绦虫属（Ditrachybothridium）区分开来。
