A new haplosphlanchnid cercaria, Cercaria kuwaitae VI sp. n., was found in the prosobranch snail Cerithidea cingulata in the Kuwait Bay. Details are presented on the morphology and behavior of the cercaria and the encystment process. The new cercaria is a biocellate, distome, with a prominent single sac-like intestinal cecum extending well posterior to the ventral sucker and develops in simple sporocysts. It differ from known haplosplanchnid cercariae in the absence of finger-like processes on the tail, and the presence of V-shaped excretory vesicle extending beyond ventral sucker and the presence of cervical glands. The surface topography of the cercaria and its sporocyst is examined by scanning electron microscopy. This is the first haplosplanchnid cercaria to be described from a Cerithidea species.
在科威特湾的沟纹蟹守螺（Cerithidea cingulata）中发现了一种新的单睾吸虫尾蚴——科威特单睾吸虫尾蚴六新种（Cercaria kuwaitae VI sp. n.）。本文详细介绍了该尾蚴的形态、行为及包囊形成过程。这种新尾蚴为双细胞、双口型，有一个突出的单个囊状肠盲囊，向后延伸至腹吸盘后方很远，在简单的子胞蚴中发育。它与已知的单睾吸虫尾蚴不同之处在于尾部没有指状突起，有一个V形排泄囊延伸至腹吸盘之外，且有颈腺。通过扫描电子显微镜检查了尾蚴及其子胞蚴的表面形貌。这是首次从蟹守螺属物种中描述的单睾吸虫尾蚴。
