Molecular phylogenetic analyses of the genus Chlorospingus (Aves: Emberizidae) indicate that the genus is not mono-phyletic because Chlorospingus flavovirens is actually a member of the tanager family (Thraupidae), in which its closest relatives are members of the genus Bangsia. We thus propose that C. flavovirens be transferred to Thraupidae and to the genus Bangsia.
