During surveys of helminth parasites of marine fishes from the Pacific coast of the Guerrero State in Mexico, 2 undescribed species of Haliotrema Johnston and Tiegs, 1922 (sensu Young, 1968) (Dactylogyridae) were found infecting the gills of the giant hawkfish Cirrhitus rivulatus Valenciennes, 1846 (Perciformes, Cirrhitidae), i.e., Haliotrema cirrhitusi n. sp. and Haliotrema pollexinus n. sp. The new species are similar with respect to the morphology of the anchors with base-shaft junction crazed, hinged, or both; dorsal anchors with an elongate superficial root; a tubular male copulatory organ (MCO) with a cylinder-shaped base diagonally opening; and a membranous accessory piece, shaped like a vane, encircling MCO to form 2 complete spirals from the anterior margin of base to the terminal portion of the MCO. While H. cirrhitusi and H. pollexinus differ from all other species of the genus in the general morphology of the copulatory complex, only H. pollexinus notably differs from all these species in having a superficial, blade-like projection from the inner surface on the distal shaft of anchors. Haliotrema cirrhitusi and H. pollexinus are the only members of the genus recorded in the Mexican Pacific and from a cirrhitid host.
在对墨西哥格雷罗州太平洋沿岸海洋鱼类的蠕虫寄生虫进行调查期间，发现了2种未描述的哈氏吸虫属（Haliotrema Johnston和Tiegs，1922年）（根据Young，1968年的分类）（指环虫科），它们感染了1846年命名的巨鹰鱼（Cirrhitus rivulatus Valenciennes）（鲈形目，鹰鱼科）的鳃，即 cirrhitusi哈氏吸虫新种和pollexinus哈氏吸虫新种。这两个新物种在形态上相似，锚具的基部与轴的连接处有裂纹、铰接或两者皆有；背锚具具有细长的表面根部；管状雄性交配器官（MCO），基部呈圆柱形，斜向开口；还有一个膜状附属物，形状像叶片，环绕MCO，从基部前缘到MCO末端形成2个完整的螺旋。虽然cirrhitusi哈氏吸虫和pollexinus哈氏吸虫在交配复合体的总体形态上与该属的所有其他物种不同，但只有pollexinus哈氏吸虫在锚具远端轴的内表面有一个表面的、叶片状的突出物，这一点明显不同于所有这些物种。cirrhitusi哈氏吸虫和pollexinus哈氏吸虫是该属在墨西哥太平洋地区以及从鹰鱼科宿主中记录的仅有的成员。
