A checklist based on previously published records and original data is presented for the helminth parasites reported in 35 fish species from nine families from the Rio Papaloapan basin, east Mexico. The checklist contains 85 taxa from 39 helminth families. Trematodes and nematodes were the most abundant taxonomic groups. The helminth fauna in the fish of the Papaloapan River basin predominantly consists of Neotropical species that are largely autogenic. The introduced species Centrocestus formosanus was the most widely distributed helminth, infecting 16 host species. Ten of the recorded helminth species have only been found in fish from the Papaloapan. This inventory contributes 157 new host records, and reports the presence of 30 helminth species in the Papaloapan for the first time . This inventory shows the richness of helminth parasite species in the fish of the Papaloapan River basin in comparison with the other hydrological basins in Mexico. It also demonstrates that this fauna is typically Neotropical and quite similar to that from the neighboring basins of the Grijalva-Usumacinta system and the Yucatan Peninsula. The data also suggest highly effective transmission between environments within the same basin and that the regional parasite fauna is strongly influenced by fish community composition.
本文给出了一份基于先前已发表记录和原始数据的清单，该清单涵盖了墨西哥东部帕帕洛阿潘河流域9个科35种鱼类体内报告的蠕虫寄生虫。这份清单包含来自39个蠕虫科的85个分类单元。吸虫和线虫是数量最多的分类类群。帕帕洛阿潘河流域鱼类体内的蠕虫动物群主要由新热带界物种组成，这些物种大多是自生的。外来物种台湾棘带吸虫是分布最广的蠕虫，感染16种宿主。所记录的蠕虫物种中有10种仅在帕帕洛阿潘河流域的鱼类中被发现。这份清单新增了157条宿主记录，并首次报告了帕帕洛阿潘河流域存在30种蠕虫物种。与墨西哥的其他水文流域相比，这份清单显示了帕帕洛阿潘河流域鱼类体内蠕虫寄生虫物种的丰富性。它还表明，该动物群是典型的新热带界动物群，与格里哈尔瓦 - 乌苏马辛塔系统相邻流域和尤卡坦半岛的动物群非常相似。数据还表明，同一流域内不同环境之间的传播非常有效，并且区域寄生虫动物群受到鱼类群落组成的强烈影响。
