Well, I see nobody else has posted, so I'll try and help. Let me say upfront, pickings are SLIM in Augusta. And let me also say that I haven't been to any of these places, but may very well be your only choices.
There's a place called Gagliano's Italian Bistro right downtown...ranked 11 out of 52 on TripAdvisor (decent review) but not well liked on Yelp.
Cloud 9 at the Senator Inn (Western Ave) is probably the most well known and liked restaurant in Augusta and while it isn't purely Italian, it does have alot of Italian options. It's ranked 4 out of 52 on TA, and gets good reviews on Yelp.
There's also a new place called Charlamagnes which isn't necessarily an Italian place either, but has some Italian options and gets good reviews on both TA and Yelp.
Now, if you don't want Italian, i can certainly recommend the Liberal Cup or Slates in neighboring Hallowell.
But if you have your heart set on Italian, I think I would personally try one of the options at Cloud 9.
