We intended to describe 2 digenean trematodes found from a Chinese sea snake, Laticauda semifasciata, as the new fauna in the Republic of Korea. The snake was caught offshore of Aewol-eup, Jeju-do, in August 2017. Two species of fluke were found in the lung and intestinal tract of the snake in the process of necropsy. They were identified as Pulmovermis cyanovitellosus Coil and Kuntz, 1960 and Harmotrema laticaudae Yamaguti, 1933, respectively based on the morphological characters. Pulmovermis cyanovitellosus showed elongated body with well-developed and elongated male genital system and compact vitelline. And H. laticaudae was characterized by linguiform body with heavily armed cirrus with excretory system. This is the first time both species have been reported and described off the Korean coast. We provide morphological descriptions with some comments on their biology and geographical distribution. In addition, the taxonomic validity of the genus Hydrophitrema Sandars, 1960 was discussed, in terms of morphological descriptions and host ranges. This study provides novel insight into digenean fluke species existing off the coast of Korea.
我们旨在描述在中国海蛇半环扁尾海蛇（Laticauda semifasciata）体内发现的两种复殖吸虫，将其作为大韩民国的新动物区系。该海蛇于2017年8月在济州岛涯月邑近海捕获。在尸检过程中，在海蛇的肺部和肠道中发现了两种吸虫。根据形态特征，它们分别被鉴定为1960年Coil和Kuntz发现的蓝卵肺吸虫（Pulmovermis cyanovitellosus）以及1933年山口发现的扁尾海蛇哈氏吸虫（Harmotrema laticaudae）。蓝卵肺吸虫身体细长，雄性生殖系统发达且细长，卵黄腺紧密。而扁尾海蛇哈氏吸虫的特征是身体呈叶状，阴茎囊武装发达，具有排泄系统。这是这两个物种首次在韩国沿海被报道和描述。我们提供了形态学描述，并对它们的生物学和地理分布进行了一些评论。此外，从形态学描述和宿主范围方面讨论了1960年Sandars发现的水栖吸虫属（Hydrophitrema）的分类有效性。本研究为韩国沿海存在的复殖吸虫种类提供了新的见解。
