【摘要】Phylogenetic analyses based on mitochondrial genes were conducted to reconstruct species relationships within the aphid genus Mollitrichosiphum (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 river catchments and the isolation of Hainan Island were probably important factors contributing to the diversification of species in this genus [Current Zoology 57 (6):806-815,2011].
