Italian admixture!
This map has a distribution that seems to include mostly the non-Celtic/Germanic ancestry in Italy. Despite the heavy ancient Greek colonisation of southern Italy, this admixture is quite distinct from the Greek one, except in the Aegean Islands, Anatolia and Cyprus, where 23andMe doesn't seem to distinguish between Italian and Greek ancestry. This is because insular Greeks are very close genetically from South Italians. This admixture seems to be found exclusively within the boundaries of the Roman Empire, and consequently might well have been spread outside Italy/Greece by the ancient Romans. The hotspots in Galicia and central/southern Portugal can be explained by the high percentage of Roman colonies in those regions, but also perhaps by the displacement of the substantial Roman population from western Andalusia to Portugal over the centuries.
