This study aimed to report the first record of the occurrence of the parasite Livoneca guianensis in Leporinus fasciatus in Brazil. In September 2019, during surveys of the parasites in 12 specimens of L. fasciatus from the lower Jari River basin, in Amapá State, Brazil, one specimen of L. guianensis was found in the tongue of one host. The prevalence of L. guianensis was 8.3%, and it was observed that this parasite has a geographic distribution restricted to South America, parasitizing fish species from Guyana and Brazil. This study contributed to the first report on the occurrence of L. guianensis for L. fasciatus in Brazil. In addition, increased the knowledge on the geographic distribution of this parasite with morphometric data, which are scarce for this Cymothoidae.
本研究旨在报告寄生虫 Livoneca guianensis 在巴西 Leporinus fasciatus 中首次出现的记录。2019 年 9 月,在对巴西阿马帕州下雅里河流域的 12 条 Leporinus fasciatus 寄生虫进行调查期间,在一条宿主的舌头上发现了一条 Livoneca guianensis。L. guianensis 的流行率为 8.3%,观察到这种寄生虫的地理分布仅限于南美洲,寄生在圭亚那和巴西的鱼类物种上。本研究为巴西 Leporinus fasciatus 中 Livoneca guianensis 的首次出现做出了贡献。此外,通过形态测量数据增加了对这种寄生虫地理分布的了解,而这些数据对于 Cymothoidae 来说是稀缺的。
