Austrodiplostomum Szidat & Nani, 1951 is a genus of parasitic digenetic trematodes widely distributed in the Neotropical region. Infects a wide variety of species, families and requests for freshwater fish. We identify samples of Austrodiplostomum sp, based on metacercariae isolates from eyes of tambaqui (Colossoma macropomum), a fish of high commercial importance in Brazil, and widely consumed by the population of the northern region. The sequences obtained clustered with A. compactum. This is the first report of the occurrence of diplostomids in farmed tambaqui in Amazonia.
奥氏双穴吸虫属（Austrodiplostomum Szidat & Nani，1951）是一类寄生性复殖吸虫，广泛分布于新热带地区。它能感染多种淡水鱼，涉及多个种类、科属。我们基于从坦巴基鱼（Colossoma macropomum）眼睛中分离出的囊蚴样本鉴定出奥氏双穴吸虫属的样本，坦巴基鱼在巴西具有很高的商业价值，并且被该国北部地区的人们广泛食用。所获得的序列与紧凑奥氏双穴吸虫（A. compactum）聚类。这是亚马逊地区养殖坦巴基鱼体内出现双穴吸虫的首次报道。
