Uroleucon Mordvilko is the largest genus in the Macrosiphini (Hemiptera, Aphididae) and most of its species live on species of Asteraceae. Uroleucon nahuelhuapense Nieto Nafría von Dohlen sp. n. is described from apterous viviparous females collected on Adesmia boronioides (Fabaceae) in a locality of Neuquén province (Argentina). The morphological characters and the sequence of the tRNAleu-COII mitochondrial locus support the inclusion of the new species in the genus Uroleucon. Apterous viviparous females of Uroleucon adesmiae Mier Durante Ortego collected in two Argentinean localities have also been studied and ranges of several quantitative features have been modified. The identification key for the Uroleucon species known in South America by Nieto Nafría et al. (2007) has been modified to include the new species.
尤蚜属（Uroleucon）是大蚜族（半翅目，蚜科）中最大的属，其大多数物种寄生于菊科植物上。纳韦尔瓦皮尤蚜（Uroleucon nahuelhuapense）是 Nieto Nafría 与 von Dohlen 描述的新物种，其无翅胎生雌蚜采自内乌肯省（阿根廷）一处地方的博洛尼状阿德木（豆科）上。形态特征以及线粒体 tRNAleu - COII 基因座序列支持将该新物种归入尤蚜属。对采自阿根廷两个地方的阿德木尤蚜（Uroleucon adesmiae）的无翅胎生雌蚜也进行了研究，并对几个数量特征的范围进行了修正。Nieto Nafría 等人（2007 年）给出的南美洲已知尤蚜属物种检索表已作修改，以纳入该新物种。
