Thank you keravnos.

Italiotai Apeirotai perhaps, the Epirote Italic Greeks?

P.S.: The Year in History states that the Antigonid Makedones counted their calendar from 317BC, start of the reign of Alexanders last rightful heir Alexander IV. So I conclude the year 272BC was the year 46 for the Makedones, is that right? Or did they also counted in Olympiads, or in years after the first Olympics. I guess they didn't call the year after the Eponymous Archon of Athens, right?
