I agree with Myrmica.

The key provided if followed through as 12 antennal segments will easily follow to Myrmica.

I think it looks a bit like an ant

19, 20, 21, 22, 23, 24, 26, 27, 28, 29 is the key I followed. Some of the options I just ignored and didn't consider, like Cardiocondyla or Monomorium, so the key was pretty quick and not very thorough. Arrived at Myrmica, which confirmed my gut feeling at the start.

My first thought was Myrmica, sculpturing on head body, and more importantly shape of petiole and post petiole are what caught my eye.

I was thinking either Myrmica or Stenamma.

Eye size and the very rugose sculpturing rule out Stenamma. Stenamma have rather small eyes and the sculpturing is usually very fine and punctate, and also covered in short hairs.

Good job, Myrmica is one of the trickier genera.

I thought the opposite tbh.

Stenamma also tend to have shorter propodeal spines and a prominent petiolar "stem" where it connects to the propodeum. I do agree with Myrmica on this one though, especially due to the highly prominent sculpturing and long propodeal spines. I could recommend some keys to get this one down to species if needed. I know Myrmica are real tricky, but it's worth a shot.
