A phylogeny of the tribe Aphidini (Hemiptera: Aphididae) was reconstructed from three gene fragments: two mitochondrial regions, partial tRNA-leucine + cytochrome oxidase II (tRNA/COII), partial 12S rRNA + tRNA-valine + 16S rRNA (12S/16S) and one nuclear gene, the elongation factor-1 alpha (EF1 alpha). Bayesian phylogenetic (BP) analyses were performed oil each individual dataset of tRNA/COII, 12S/16S and EF1 alpha, and maximum parsimony (MP), Bremer Support test, maximum likelihood (ML) and BP analysis were performed oil the combined dataset. After comparing Our molecular phylogenetic results with the classic classification based on morphological and ecological data, we analysed three main issues: the monophyletic relationships among tribes and subtribes, the validities of the latest taxonomic positions of genera and species and the status of certain Aphis species groups. Our results indicate that 36 of the species analysed, with the exception of Cryptosiphum artemisiae, are clustered within the clade of Aphidini. Also, the 28 species representative of the subtribe Aphidina were separated from the eight species representative of Rhopalosiphina; each monophyletic subtribe was supported by significant P-values in the combined analysis. According to our results, Cryptosiphum should be moved to Macrosiphini because it is more closely related to the genera Lipaphis and Brevicoryne. The genus Toxopfera was recovered as non-monophyletic. In Rhopalosiphina, three genera, Hyalopterus, Rhopalosiphum and Schizaphis, were relatively closer to each other than to the genus Melanaphis. In the relationships between species-groups among Aphis, most species were separated into two main lineages; the fabae group seemed to be more closely related to the spiraecola and craccivora group rather than to the gossypii group.
