Diechodactylus joaberi n. g., n. sp. is described from the body surface of the banded knifefish Gymnotus carapo L. (Gymnotiformes: Gymnotidae) from southeastern Brazil. The new genus is proposed to accommodate species with five pairs of hooks in anterior bilateral clusters on the haptor, three pairs of hooks in a single cluster on the posterior margin of the haptor, sclerites R1 associated with the superficial bar, and confluent intestinal caeca. The presence of five pairs of hooks in two bilateral clusters anterior in the haptor permits the differentiation of species of Diechodactylus from species of all known genera of the Gyrodactylidae. The genus is likely a member of a clade of the Gyrodactylidae comprising genera with a similar hook distribution.
乔阿贝氏双指虫属（Diechodactylus），新物种，是从巴西东南部的带状刀鱼（Gymnotus carapo L.，裸背电鳗目：裸背电鳗科）体表描述而来。提出这个新属是为了容纳以下特征的物种：在吸盘前部双侧簇中有五对钩，在吸盘后缘单个簇中有三对钩，与浅杆相关的骨片R1，以及融合的肠盲囊。吸盘前部两个双侧簇中存在五对钩，这使得双指虫属的物种能够与三代虫科所有已知属的物种区分开来。该属可能是三代虫科一个分支的成员，该分支包括具有相似钩分布的属。
