Fellow Naturalists, I found an interestig plant about last week. I potted it because it's getting quite cold outside and i didn't want it to die. I've never seen this species in my area. The A.I has no ideea what it is nor do my neighbours. Would you mind helping me identify it?

I've never seen this species in my house before. The workers are about 5 mm with female alates reaching about 1cm in length. The workers look a lot like Lasius Niger workers, they could belong to the same genus.
