Wow, you should record the species in Florida so they can show up on antmaps. Also Otter, he is in Florida, and Acromyrmex aren't that far east so its probably not that. I wish I had your luck finding cool queens. All I've found this year are 2 Camponotus queens, tetra, molesta (which subsequently died), and vividula.

Man I wish I could have tetramorium but all I have here is RIFA and N. fulva which are now wiping them out. They're gonna be the next big invasive since they're immune to RIFA venom.

Ok so it is trachymyrmex. They looked exactly like acromyrmex. I don't know anything about anything as far as attines go, my area of expertise is odontomachus.
 
My trap-jaws are odontomachus bauri, I'm 100% sure. Found in the keys.

Odontomachus bauri has no collection records in the US. You’re likely dealing with O. ruginodis; a smaller species that’s very common from Central Florida southward, (very dominant on the keys) especially near disturbed habitat. O. brunneus is a slightly larger species that’s also possible, but they’re less common in the southern tip of Florida with only a couple collections from the keys.

Yeah, Acromyrmex and Atta both delineated from Trachymyrmex, though they are much more similar to Acromyrmex.

Hm. Miiight be brunneus, it's not ruginodis. I've seen ruginodis and mine are quite a bit bigger.

If they’re larger in size (8-10mm) then they’re O. brunneus. It’s very safe to assume they’re not O. bauri given they’re a species yet to be discovered in the state of Florida. (versus the former, which is found all over the state) They’re also fairly identical to the naked eye, though brunneus can be reliably separated due to their dense abdominal pubescence, particularly on the first tergite.

Tetramorium are destructive in almost all ecosystems they invade. They’re like limited RIFAs of the north.

I believe you may have misidentified a few of the species you have

There are no collection records of Odontomachus bauri in the state of Florida. Of the species we have here, brunneus, haematodus, relictus, and ruginodis, yours is most likely ruginodis. It cannot be haematodus or relictus as they are not present within the keys, and brunneus tends to be less common the further south you go.

[rcbuggy88]

Super Frank, that topic has already been gone over. I believe the consensus is its Odontomachus bruneus. Man, I wish we had trapjaws here is Cali.

[NickAnter]

We probably do somewhere in the desert. Just probably super rare. There are records of them in AZ that are fairly close to Cali.
