Rheotanytarsus is a speciose genus, currently composed by more than 100 nominal species distributed worldwide, 19 are known from the Neotropical region, four from South America and only one is registered for Peru. In the present study, a new species is described and illustrated based on males collected in the Peruvian Andes. In addition, the key to the South American species is updated and a distribution map of them is provided. Rheotanytarsus amaru sp. n. is easily distinguished from the congeneric species by the dark general coloration and the hypopygial morphology.
流水跗摇蚊属是一个物种丰富的属，目前由分布于全球的100多个命名物种组成，新热带地区已知有19种，南美洲有4种，而秘鲁仅记录有1种。在本研究中，基于在秘鲁安第斯山脉采集的雄性标本描述并图示了一个新物种。此外，更新了南美洲物种检索表并提供了其分布图。阿玛鲁流水跗摇蚊新种（Rheotanytarsus amaru sp. n.）通过整体深色以及尾下叶形态很容易与同属其他物种区分开来。
