Comparative phylogenetic analysis was performed using partial mitochondrial Cytochrome Oxidase subunit I (COI) and nuclear Elongation Factor 1 alpha (EF-1α) sequences. Partial COI data indicate the possibility of the early divergence in the D. pyri ? D. reaumuri stem, which might have occurred even before the splitting of the common ancestral species of D. reaumuri ? D. plantaginea complex. Such a conclusion seems to be compatible with the available data on the host specificity, life cycles and distribution of both species. The introductory phylogenetic analysis based on partial COI and EF-1α sequences indicate the need for reconsideration of the subgeneric structure in the genus Dysaphis.} }
