Abstract. Marine leeches are sanguivorous parasites either on sea turtles (family Ozobranchidae) or on elasmobranch and teleost fishes (family Piscicolidae), with the exception of Mysidobdella, which may feed on mysid shrimp. The marine leeches of Australia and New Zealand are poorly known, especially those on teleost fishes. Collections of marine leeches from all major museums in Australia and New Zealand were examined, as well as many specimens sent to the author. Ozobranchus branchiatus and O. margoi were found on sea turtles in Australia. Seven genera and 14 species of fish leeches were found in Australia; 6 genera and 10 species of fish leeches were found in New Zealand. Two genera (Pontobdella and Branchellion) and four species (P. leucothela, P. moorei, B. australis and B. plicobranchus) occur in both Australia and New Zealand. No genus is endemic to Australia, but four species are endemic based on current records (Austrobdella bilobata, Austrobdella translucens, Trachelobdella leptocephali and Pterobdella platycephalus). Two genera (Bdellamaris and Leporinabdella) and three species (B. manteri, B. eptatreti, and L. digglesi) are endemic to New Zealand based on current records. The marine leeches of Australia and New Zealand are a mix of endemic species, those of tropical or subtropical origin, and those of subantarctic origin.

澳大利亚和新西兰的海洋和河口水蛭（水蛭科：Ozobranchidae 和 Piscicolidae），是该物种的关键

摘要。海洋水蛭是海龟（Ozobranchidae 科）或硬骨鱼类（Piscicolidae 科）上的食血寄生虫，但Mysidobdella 除外，它们可能以糠虾为食。澳大利亚和新西兰的海洋水蛭鲜为人知，尤其是硬骨鱼类的水蛭。检查了澳大利亚和新西兰所有主要博物馆的海洋水蛭收藏品，以及寄给作者的许多标本。在澳大利亚的海龟身上发现了 Ozobranchus branchiatus 和 O. margoi。在澳大利亚发现了 7 属 14 种水蛭；在新西兰发现了 6 属 10 种水蛭。澳大利亚和新西兰有两个属（Pontobdella 和 Branchellion）和四个种（P. leucothela、P. moorei、B. australis 和 B. plicobranchus）。没有一个属是澳大利亚特有的，但根据目前的记录，有四个物种是地方性的（Austrobdella bilobata、Austrobdella translucens、Trachelobdella leptocephali 和 Pterobdella platycephalus）。根据目前的记录，新西兰特有两个属（Bdellamaris 和 Leporinabdella）和三个物种（B. manteri、B. eptatreti 和 L. digglesi）。澳大利亚和新西兰的海洋水蛭是地方性物种、热带或亚热带来源的物种以及亚南极来源的物种的混合体。
