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.

译文

:Diechodactylus joaberi n。 g。 sp。从巴西东南部的带状刀鱼Gymnotus carapo L.(Gymnotiformes:Gymnotidae)的体表描述。提出了新的属,以容纳具有五对钩的物种,在前臂的双侧前集群中有五对钩,在后臂的后缘的单个集群中有三对钩,与浅表杆相关的巩膜R1,和汇合的肠盲肠。在触角前部的两个双侧簇中,五对钩的存在允许区分狄氏龙虾属和所有已知的丁香龙属。该属很可能是包括具有相似钩分布的属的丁香科的进化枝的成员。
