This is the first confirmed report of Pholeter gastrophilus infecting three delphinid species from Brazilian waters, Steno bredanensis, Tursiops truncatus, and Feresa attenuata. The worms were identified based on morphological and molecular data using the 28S rDNA and COI mtDNA genes. The present study increases the distribution area of this trematode species and provides new molecular data to be used in future phylogenetic studies of the group, thus contributing to scientific knowledge on marine parasites.

Pholeter gastrophilus (Trematoda: Heterophyidae)，一种来自巴西水域的海豚寄生虫

这是Pholeter gastrophilus感染来自巴西水域的三种海豚科动物Steno bredanensis、Tursiops truncatus和Feresa attenuata的首次确认报告。蠕虫是基于形态学和分子数据使用 28S rDNA 和 COI mtDNA 基因识别的。本研究增加了这种吸虫物种的分布面积，并提供了新的分子数据，可用于该群体未来的系统发育研究，从而为海洋寄生虫的科学知识做出贡献。
