Over the past dozen years, considerable effort has been devoted to unravelling the higher‐level phylogenetic relationships of viviparous aphids (Aphididae). However, to date, there is still no commonly accepted phylogenetic hypothesis. In this study, we establish a robust phylogenetic framework for the Aphididae based on mitochondrial genome sequences of 35 aphid species, 22 of which are newly reported. Phylogenetic inferences are performed using multiple data sets, alternative partitioning schemes and different model‐based methods. Our analyses result in well‐supported backbone relationships for the major lineages of aphids, suggesting the feasibility of mitogenome data for resolving phylogenetic questions in aphids. Mindarinae is strongly supported as the earliest branching lineage within Aphididae. A monophyletic clade comprising Calaphidinae, Phyllaphidinae and Saltusaphidinae is corroborated to be the sister group to the species‐richest subfamily Aphidinae. In addition, the morphologically defined subfamily Eriosomatinae is uncovered to be non‐monophyletic.
