Aphids are intimately associated with their host plants. E volutionary lability of host association is common within heteroecious aphid lineages, whereas our knowledge of host‐use evolution in non‐host‐alternating aphids is limited. In the present study, we construct the first detailed molecular phylogeny of the monoecious aphid tribe G reenideini based on three mitochondrial genes ( COI , COII and C ytb ) and one nuclear gene ( EF ‐ 1α ), and investigated its history of host association. Maximum likelihood and B ayesian phylogenies strongly support the monophyly of G reenideini and most constituent genera. Divergence time estimates and character reconstructions suggest that G reenideini may have originated during the L ate C retaceous to early P aleogene, which accompanies the origin of its ancestral host, members of the family F agaceae. Colonisation of novel host plants has occurred multiple times during the evolutionary history of G reenideini, thereby leading to current patterns of host association. We suggest that directly shifting to novel hosts, together with expanding host range onto pre‐existing, unused plants, has probably promoted diversification in this tribe.
