Phylogeny and species differentiation of Mollitrichosiphum spp. （Aphididae, Greenideinae） based on mitochondrial CO1 and Cyt b genes

Phylogenetic analyses based on mitochondrial genes were conducted to reconstruct species relationships within the aphid genus MoUitrichosiphum （Aphididae, Greenideinae）. MP and Bayesian analysis results using COI and Cyt b datasets, and combined MP, ML and Bayesian analysis of both were consistent with a morphologically supported monophyly. Subdivision of the genus into two subgenera was strongly supported. Samples of each included species form monophyletic clade, respectively; and the result implied the valid status of related species in this genus. These results suggest some surprising hypotheses regarding the phylogeography of the genus： the uplift of the Tibetan Plateau, reorganization of major fiver catchments and the isolation of Hainan Island were probably important factors contributing to the diversification of species in this genus .
