Queen ID El Paso TX Aug. 2019

[SouthWesternAnts]

Hi, I just caught this queen ant and was wondering what species it is. I caught this queen near the El Paso TX area today and I think this is a type of pheidole species but am unsure of which one specifically or if it's a different ant species all together. She has a black to very dark brown/reddish color to her and has some spines coming out of her end of her thorax. She has a very rigid/sharp figure to her. I included a picture I found online(https://www.ants-kalytta.com/Formiche-Asia.html?f=P#) of an ant queen that resembles the one I have caught but the description said it was a Pheidole sp. and that it was from Asia but not specifically which species.

Thanks.

They look like Atta texana leafcutter ants.

No, it's an Acromyrmex sp leafcutter ant queen

I thought Atta had three spikes and Acromyrmex had four.
