From Sarno et al.
It is too bad that Syracuse was not studied, since Trapani and Syracuse were two of the last places in Sicily to lose the Greek language.

First, it places mainland Greeks and Albanians, overall, in a cluster that is more related to northern Italians rather than southern Italians. Then, it divides Greek islands into two clusters, one of which is shared with east-central Sicily and Calabria, and then the other with Trapani and Apulia/Basilicata.
"On the other hand, individuals from SSI, Crete and the Aegean/Dodecanese Greek Islands are mostly assigned to two other groups. The first one (CE-Sicily, limegreen in Fig. 3) is observed mainly in Central-Eastern Sicily and Calabria (excluding Calabrian Greeks), jointly with various Cretan and Anatolian/Dodecanese Greeks. The second one (AW-Sicily, purple in Fig. 3) encompasses individuals from the geographically opposed areas of Basilicata/Apulia (including Salentino Greeks) and Western Sicily (most notably Sicilian Arbereshe), as well as the remaining individuals from both continental and insular Greece. Importantly, these clusters appear tightly related with each other, showing some degree of admixture within a genetically continuous area (Supplementary Fig. S5, Supplementary Table S4). However, they provide the framework for a finer exploration of subtle differentiation patterns, showing differences in their representativeness within different SSI populations. In fact, the AW-Sicily cluster is more properly related to all the Greek-speaking populations (not only Crete and Aegean/Dodecanese Greeks, but also Continental Greece), while the CE-Sicily one is essentially observed in the Mediterranean ‘continuum’ populations (i.e. Southern Italy and Greek-speaking islands). Finally, Cypriots and Calabrian Greeks exhibit private population-specific genetic clusters (white and aquamarine in Fig. 3, respectively)."
They do not find any Balkan IBD sharing in Calabria or east-central Sicily, but they do find it in Trapani and Apulia/Basilicata:
"Interestingly, despite showing much lower values of sharing, some Balkan IBD-relatedness also emerges in Greek-speaking islands as well as in Apulia and Western Sicily, presumptively reproducing some forms of interaction with Greece and the Balkans in the very recent ancestry of these areas, as consistently signalled by a common sharing of individuals in the FineSTRUCTURE AW-Sicily cluster (see also Supplementary Information)."
They also find additional Steppe input compared to Calabria and east-central Sicily:
"In most cases, these events depict populations from the ‘continuum’, and particularly the two SSI-clusters (CE-Sicily and AW-Sicily), as a mixture of Sardinian and Caucasus or Near Eastern related groups (Fig. 5, Supplementary Table S7). In addition, populations from the Apulia/West-Sicily seem to have experienced further mixtures involving Sardinia and Eastern-Europe. "
