Ant ID Help

[Mattisius]

I’m new to ant keeping and I was working outside and saw what I originally thought might be a queen. Now I’m not so sure. The ant looks like Solenopsis molesta or Monomorium pharaonis. The ant seems too large to be a regular worker ant, but it doesn’t have the enlarged thorax like Solenopsis invicta which is the only ant I’m slightly familiar with. Even though I don’t think it’s a queen at this point, I’d still like help IDing for future reference.
