Hello! I've been observing this ants for 8 years and I'm pretty sure they're Acromyrmex Lobicornis (https://www.antwiki.org/wiki/Acromyrmex_lobicornis) or Acromyrmex Lundii (https://www.antwiki.org/wiki/Acromyrmex_lundii), but can't find any image of a queen and I've never seen one of them. If someone knows where to find more information about them or when can I catch a queen, it'll be amazing. They're 8mm. aprox.

You're in luck, I'm not sure if it's Acromyrmex Lobicornis or Acromyrmex Lundii, however, it's Acromyrmex sp. and it's a queen, feast your eyes: https://drive.google.com/open?id=1MxY0aWPC6Ahfjo7KtFQhpNYnuDxtNdu2 I'm sorry that the pics aren't that good. this one is around 10mm in lengh, I found her by chance while looking at the ground on the day 29-nov-2019, but found just one though, I guess the follow a similar schedule that from an Atta sp. so I doubt I'll be seeing more from this species.... btw, I'm from Brazil, São Paulo.
