Hapalotrema mistroides (Monticelli, 1896) Stiles and Hassall, 1908 and Hapalotrema synorchis Luhman, 1935 are redescribed using specimens from the loggerhead turtle. Caretta caretta (L.). The redescription of H. mistroides is based on specimens collected by Looss and described as Hapalotrema constrictum Leared, 1862 and renamed Hapalotrema loossi Price, 1934, which is now considered a junior synonym of H. mistroides. Hapalotrema orientalis Takeuti, 1942 is considered a junior synonym of Hapalotrema synorchis. The redescriptions are consistent with the originals but provide an unreported range of variation while adding new information about the reproductive systems. Reexamination of Hapalotrema dorsopora Dailey, Fast, and Balazs, 1993 confirms the presence of a reproductive system typical for the genus and the absence of a dorsal genital pore; therefore, H. dorsopora is reduced to a junior synonym of Hapalotrema mehrai Rao, 1976. Four valid species of Hapalotrema are recognized: H. mistroides. H. synorchis, H. postorchis, and H. mehrai, and a key to the species is provided.
利用蠵龟（Caretta caretta (L.)）的标本对米氏哈氏吸虫（Hapalotrema mistroides (Monticelli, 1896) Stiles and Hassall, 1908）和联睾哈氏吸虫（Hapalotrema synorchis Luhman, 1935）进行了重新描述。米氏哈氏吸虫的重新描述基于由洛斯收集的标本，这些标本最初被描述为缩窄哈氏吸虫（Hapalotrema constrictum Leared, 1862），后被重新命名为洛斯哈氏吸虫（Hapalotrema loossi Price, 1934），现在被认为是米氏哈氏吸虫的次异名。东方哈氏吸虫（Hapalotrema orientalis Takeuti, 1942）被认为是联睾哈氏吸虫的次异名。这些重新描述与原始描述一致，但提供了未报道的变异范围，同时增加了有关生殖系统的新信息。对背孔哈氏吸虫（Hapalotrema dorsopora Dailey, Fast, and Balazs, 1993）的重新检查证实了该属典型生殖系统的存在以及背侧生殖孔的缺失；因此，背孔哈氏吸虫被降为梅氏哈氏吸虫（Hapalotrema mehrai Rao, 1976）的次异名。确认了哈氏吸虫属的四个有效物种：米氏哈氏吸虫、联睾哈氏吸虫（H. synorchis）、睾后哈氏吸虫（H. postorchis）和梅氏哈氏吸虫，并提供了物种检索表。
