Redescription is given of heteraxinid monogeneans Zeuxapta seriolae (Meserve, 1938), type species of the genus, and Zeuxapta australica Lebedev, 1968 (formerly Z. seriolae australica). Type specimens of Z. seriolae from Seriola dorsalis from Galápagos Islands were differentiated from Z. australica specimens collected by Lebedev from Seriola glandis (now Seriola lalandi) from Tasman Sea, the type locality, by the shape of the vagina, which consisted of the transversely oval central body and horizontally extended paired tubes in the former, and the transversely oval central body and short, obliquely posteriad paired extensions in the latter. Zeuxapta japonica (Yamaguti, 1940) and Zeuxapta kahala (Yamaguti, 1968) were synonymized with Z. seriolae. Hitherto undescribed Zeuxapta specimens were also examined; those from Seriola aureovittata from Japan and China, and specimens from Seriola dumerili from Japan and Spain were identified as Z. seriolae, while those from Seriola lalandi from Chile and New Zealand were identified as Z. australica. Specimens from S. lalandi (as Seriola glandis) from Heron Island, Australia described by Rohde in 1978 as Z. seriolae consisted of Z. seriolae and Z. australica.
重新描述了异胎盘单殖吸虫属的 Zeuxapta seriolae（Meserve，1938），即该属的模式种，以及 Zeuxapta australica Lebedev，1968（以前称为 Z. seriolae australica）。来自加拉帕戈斯群岛的 Dorsalis 鲷的 Z. seriolae 的模式标本与 Lebedev 从塔斯曼海（即模式产地）的大菱鲆（现在的 Seriola lalandi）中采集的 Z. australica 标本不同，前者的阴道形状为横向椭圆形中央体和水平延伸的成对管，而后者的阴道形状为横向椭圆形中央体和短的、斜向后的成对延伸。Zeuxapta japonica（Yamaguti，1940）和 Zeuxapta kahala（Yamaguti，1968）被归为 Z. seriolae 的同义词。还检查了以前未描述的 Zeuxapta 标本；来自日本和中国的 Aureovittata 鲷和来自日本和西班牙的 Dumerili 鲷的标本被鉴定为 Z. seriolae，而来自智利和新西兰的 Lalandi 鲷的标本被鉴定为 Z. australica。1978 年 Rohde 描述的来自澳大利亚赫伦岛的作为 Seriola glandis 的 S. lalandi 的标本包含 Z. seriolae 和 Z. australica。
