A new renicolid cercaria, Cercaria kuwaitae X sp. n., from the prosobranch gastropod Cerithium scabridum from Kuwait Bay is described. The new cercaria is nonstyleted gymnocephalous with voluminous Y-shaped excretory vesicle, flame cell formula 2[(3 + 3 + 3) + (3 + 3 + 3)] = 36, and without caudal fins. Surface topography of the new cercaria is studied by scanning electron microscopy. Domed papillae are abundant on the anterior and lateral aspects of the body, ciliated papillae are sparse dorsally. The ventral sucker bears nine domed papillae. Domed papillae form two circles around the oral sucker with three circles of spines in between. This is the first renicolid cercaria to be recorded in a gastropod from the Arabian Gulf region.
描述了一种来自科威特湾粗糙蟹守螺（Cerithium scabridum）（前鳃亚纲腹足纲）的新肾居科尾蚴——科威特尾蚴X新种（Cercaria kuwaitae X sp. n.）。这种新尾蚴无口针，裸头型，具有巨大的Y形排泄囊，焰细胞公式为2[(3 + 3 + 3) + (3 + 3 + 3)] = 36，且无尾鳍。通过扫描电子显微镜研究了新尾蚴体表形态。穹顶状乳突在虫体前部和侧面丰富，背侧的纤毛乳突稀疏。腹吸盘有9个穹顶状乳突。穹顶状乳突围绕口吸盘形成两个圆圈，其间有三圈刺。这是首次在阿拉伯湾地区腹足纲动物中记录到的肾居科尾蚴。
