本文根据日本南部沿海沃茨采集的蹄盖类顶壳（Vestigastropoda）的雌雄标本，描述了桡足类的4种。在腹足类的咽部和食道中发现了三种Panaietis（桡足类：剑水蚤目：Anthessiidae），其中包括两种未描述的和一种已知的。Panaietis incamerata斯泰宾，1900，P. doraconis n. sp.，和温州蜜柑P. satsuma n. sp.与其同类的区别在于第一谱系体节的背板、生殖体节、腿上刺的形状、腿1和2上刚毛的数量以及腿5的位置和形状。假刺尾鱼sp.（Cyclopoida：Pseudanthessiidae）在宿主的外套腔中发现。这桡足类的尾支的比例，电枢和比例的天线，电枢的外足类和一般形状的内足类的腿4，并存在一个post-rostral过程中不同于它的同类。
Four species of copepods are described based on specimens of both sexes from tegulid top shells (Vestigastropoda) caught from coastal waters of southern Japan. Three species, including two undescribed and one known of the genus Panaietis (Copepoda: Cyclopoida: Anthessiidae) were found in the pharynx and esophagus of gastropods. Panaietis incamerata Stebbing, 1900, P. doraconis n. sp., and P. satsuma n. sp. are distinguished from its congeners by the dorsal plates on the first pedigerous somite, the genital somite, the shape of the spines on legs, the number of setae on legs 1 and 2, and the position and shape of leg 5. Pseudanthessius imo n. sp.(Cyclopoida: Pseudanthessiidae) was found in the mantle cavity of the host. This copepod differs from its congeners in the proportions of the caudal ramus, the armature and proportion of the antenna, the armature of the exopod and general shape of the endopod of leg 4, and the presence of a post-rostral process.
