Four polyopisthocotyleans were collected from the gill filaments of carangids from off the Algerian coast, southern Mediterranean. Specimens of van Beneden & Hesse, 1863 (Gastrocotylidae) and cf. Dillon & Hargis, 1965 (Heteraxinidae) from the Mediterranean horse mackerel (Steindachner), (Meserve, 1938) (Heteraxinidae) from the greater amberjack (Risso) and Euzet & Ktari, 1970 (Pyragraphoridae) from the pompano (Linnaeus) are redescribed based on newly collected specimens. Their taxonomically important morphological features (male copulatory organ and clamp sclerites) are described and illustrated, and the morphometric variation between Mediterranean and oceanic specimens is highlighted. Careful examination of the specimens of Sproston, 1946 from the Mediterranean revealed that they exhibited unusual features compared with Dillon & Hargis, 1965 from the Pacific, mainly the absence of the terminal lappet, thus questioning previous records of this species in the Mediterranean. New geographical locality records are provided for and . The presence of cf. and in the Mediterranean is noteworthy as these monogeneans were initially described in the Pacific Ocean. This study extends the geographical range of to the southern Mediterranean.
从地中海南部阿尔及利亚海岸的鲹科鱼类鳃丝上采集到了四种多后盘吸虫。基于新采集的标本，对来自地中海竹荚鱼（施泰因达赫纳）的1863年范·贝内登和黑塞的标本（腹杯科）、来自大西洋竹荚鱼（里索）的疑似1965年狄龙和哈吉斯的标本（异斧科）、来自军曹鱼（梅泽夫，1938）的（异斧科）以及来自卵形鲳鲹（林奈）的1970年厄泽和克塔里的标本（焰盘科）进行了重新描述。描述并展示了它们在分类学上重要的形态特征（雄性交配器官和夹片），并突出了地中海标本和海洋标本之间的形态测量差异。对来自地中海的1946年斯普罗斯顿的标本进行仔细检查后发现，与来自太平洋的1965年狄龙和哈吉斯的标本相比，它们呈现出不同寻常的特征，主要是没有末端叶，因此对该物种在地中海的先前记录提出了质疑。提供了新的地理分布记录。地中海中疑似和的存在值得注意，因为这些单殖吸虫最初是在太平洋被描述的。这项研究将的地理分布范围扩展到了地中海南部。
