Can you get some high focus shots of her head with better lighting? There are a lot of small details there that can help narrow it down.

Probably Pheidole, but difficult to tell without better detail.

I wondered about Pheidole, but I didn't think they got that big. Largest Pheidole queen I've ever seen was 8mm.

Also welcome back.

Maybe its a species of Formica due to how glossy the exoskeleton is

Since this queen has two petiole nodes (waist segments), that would put her in the Myrmicinae subfamily (acorn ants, harvester ants, fire ants, etc.) Formica have one petiole node and belong to Formicinae (carpenter ants, rover ants, crazy ants.) Formica are also not present in South America, nor in most of the southern hemisphere.
