Phylogeography of the Lessonia variegata species complex

I have added the Lessonia variegata species complex and the three new described species. The four taxa are mapped and Lessonia variegata s.l. will be split into Lessonia media, Lessonia meridionalis, Lessonia septentrionalis and Lessonia variegata s.str. according to the maps. There are only small areas that overlap on the map, so very few observations will be set back to the Lessonia variegata species complex.
