The paper by Pavlova et al presents a study on the relationships within the flava and citreola groups of wagtails, based on mtDNA, obtained from specimens from many areas of the groups' geographic distributions.

The findings show that neither flava nor citreola are monophyletic, and that in all likelihood flava must be split up in (at least) three groups, namely:

• tschutschensis (with at least plexa),
• taivana (with at least macronyx), and
• flava (with at least feldegg, beema, thunbergi, lutea and leucocephala)

But the issue remains unresolved for other taxa within flava, and limits are unclear at present. So, I am postponing their inclusion here. The split between werae and citreola is a much clearer one.
