A new species of Synthesium from the bottlenose dolphin Tursiops truncatus in South Brazilian waters is described. Morphological and molecular identification was performed, and phylogenetic analyses were carried out using the ribosomal small subunit and internal transcribed spacer 1 and the mitochondrial NDH dehydrogenase subunit 3 and cytochrome c oxidase subunit 1 genes. The main characteristics of the new species are the subterminal round-shaped oral sucker, the anterior distribution of vitellaria reaching the level of the ovary and the oval-shaped testes. The results obtained with the molecular markers supported the inclusion of the specimens into the genus Synthesium. The nucleotide divergence detected for the mitochondrial genes among the new species and others of the same genus supported the erection of a new species. This is the ninth species assigned to the genus and the third Synthesium species recorded in the South Atlantic Ocean.
描述了一种来自巴西南部海域宽吻海豚（Tursiops truncatus）的新合盘吸虫物种。进行了形态学和分子鉴定，并使用核糖体小亚基、内部转录间隔区1以及线粒体NDH脱氢酶亚基3和细胞色素c氧化酶亚基1基因进行了系统发育分析。新物种的主要特征是亚末端圆形口吸盘、卵黄腺前部分布到达卵巢水平以及椭圆形睾丸。分子标记获得的结果支持将这些标本归入合盘吸虫属。新物种与同属其他物种之间线粒体基因检测到的核苷酸差异支持建立一个新物种。这是该属的第九个物种，也是在南大西洋记录的第三个合盘吸虫物种。
