This applies for the three queens:

 

Location of collection in a park with lots of trees (Yucatan, Mexico)

Date of collection June 29, 2018 (it was raining the day before)
Habitat of collection a lot of trees nearby

Nuptial flight time and date June 29, 2018 in the morning (around 11am)

 

First queen (possibly Acromyrmex?)

Length around 6mm
Coloration, hue, pattern and texture brown/dark red color, gaster a little orangeish 
Distinguishing characteristics spines in the thorax, gaster not very large (maybe semi claustral queen?)
Anything else distinctive slow moving, very similar to Acromyrmex of bigger size

Number two is a Brachymyrmex queen. 

Number three looks way more like a Formica queen to me.


I accidentally froze all my ants

I guess you're right on the 3 and 4, and probably in the 2 too. But I'm not sure about the Acromyrmex, reading in the internet and looking at pictures, it seems the species you are saying is much larger than the queen I found. My queen it's only 5mm.

Is it maybe Trachymyrmex then?

I guess you're right, Trachymyrmex seems more similar in size. Thanks!

In that case it should either be T. intermedius or T. saussuri and probably the first recorded sighting of Trachymyrmex in the region.
