摘要

伏泰电鳗，俗称poraquê，是一种广泛分布在亚马逊盆地的鱼类。本文首次报道了新谷河流域专性食血寄生虫盘状圆蚧寄生于新谷河流域伏特河鳗的记录。共检获6份寄主标本（平均全长119.5 cm），共寄生41只，其中雄19只，雌21只，流行率为100 %，平均强度为6.83 ± 2.22。寄生虫附着在寄主身体的特定部位。我们的研究结果支持了D. discoidalis对无鳞鱼类的亲和力，并有助于对poraquê，电鳗物种寄生动物群的有限认识。

First documented case of ectoparasitism in electric eel: Dolops discoidalis (Branchiura: Argulidae) infesting Electrophorus voltai (Teleostei: Gymnotidae)

Electrophorus voltai, commonly known as poraquê, is a fish species widely distributed in the Amazon Basin. This study presents the first record of parasitism by Dolops discoidalis, an obligate hematophagous ectoparasite, in E. voltai from the Xingu River Basin. Six host specimens were examined (mean total length: 119.5 cm), harboring 41 parasite individuals (19 males and 21 females), with a prevalence of 100 % and a mean intensity of 6.83 ± 2.22. Parasites were attached to specific regions of the host's body. Our findings support the affinity of D. discoidalis for scaleless fish and contribute to the still limited knowledge of the parasitic fauna of poraquê, Electrophorus species.
