In the whole of Argentina and Chile, southern South America in this paper, 20 species of the genus Aphis hosted in species of Asteraceae were known; eleven of them are native South American, and those introduced are mostly polyphagous and widespread. The Chilean regions and the Argentine provinces in which each one of them is known, as well as the host plants on which it has been recorded, are listed. New data of 15 of them are presented, with several first records in different Argentine provinces or hosted on diverse plants: The knowledge of A. conspicua and A. fuentesi, which were recently described living on species of Baccharis, is improved from specimens respectively collected on Senecio and Gutierrezia. A. rogerblackmani Nieto Nafra, Ortego Mier Durante sp. n. is described from apterous and alate viviparous females, oviparous females and males collected on Baccharis in Argentina. Other four species are described from apterous and alate viviparae: A. gutierreziae Ortego, Mier Durante Nieto Nafra sp. n., collected on species of Gutierrezia in Argentina, A. hyalis Mier Durante, Nieto Nafra Ortego sp. n., collected on Hyalis argentea in Argentina, A. pulverea Nieto Nafra, Moreno-Gonzlez Ortego sp. n., collected on species of Senecio in Chile and Argentina, and A. sanrafaelina Ortego, Mier Durante Nieto Nafra sp. n., collected on Tagetes mendocina, Thymophylla pentachaeta and Pectis odorata in Argentina. The intraspecific diversity of Aphis pulverea has been analysed by a principal component analysis followed by hierarchical clustering of principal components. An identification key to viviparous females of the species of Aphis hosted in Asteraceae and known in southern South America is presented.
在整个阿根廷和智利，即本文中的南美洲南部，已知有 20 种蚜属物种寄生于菊科植物；其中 11 种为南美本地种，而那些引入的物种大多为多食性且分布广泛。本文列出了每种物种已知的智利地区和阿根廷省份，以及记录到它们栖息的寄主植物。本文还介绍了其中 15 种的新数据，包括在不同的阿根廷省份的首次记录或在不同植物上的记录：最近描述的生活在 Baccharis 属植物上的 A. conspicua 和 A. fuentesi 的知识，是根据分别在 Senecio 和 Gutierrezia 上采集的标本得到的。A. rogerblackmani Nieto Nafra, Ortego Mier Durante sp. n. 是从阿根廷 Baccharis 上采集的无翅和有翅胎生雌性、产卵雌性和雄性描述的。另外 4 种是从无翅和有翅胎生雌性描述的：A. gutierreziae Ortego, Mier Durante Nieto Nafra sp. n.，采集于阿根廷的 Gutierrezia 属植物，A. hyalis Mier Durante, Nieto Nafra Ortego sp. n.，采集于阿根廷的 Hyalis argentea，A. pulverea Nieto Nafra, Moreno-Gonzlez Ortego sp. n.，采集于智利和阿根廷的 Senecio 属植物，和 A. sanrafaelina Ortego, Mier Durante Nieto Nafra sp. n.，采集于阿根廷的 Tagetes mendocina、Thymophylla pentachaeta 和 Pectis odorata。通过主成分分析和主成分聚类分析对 Aphis pulverea 的种内多样性进行了分析。本文还提供了菊科植物寄生蚜属物种有翅胎生雌性的鉴别特征。
