Looks a bit too shiny and small to be C. modoc. (Unless there's a small version of C. modoc)

C. herculeanus possibly.

 

Might be the same as this one:

Well I have about 20 of these queens. I will measure all of them later this week and post the length. Just to make sure this one isn't an anomaly.

I thought herculeanus had more red on its thorax. I'm not very sure, I've never seen modoc or herculeanus in person.

Is there any other distinguishing characteristics that will separate these two?

Here are the sizes of the ones caught this season.

13 mm x3
14 mm x6
15 mm x8
16 mm x2

Not sure if this helps.

Is there some other part of the ant I could take a pic of that would help ID it further?

Interesting that’s a lot of size variation. Can we get a shot of the gaster from above and afar? More specifically is there any hair on the gaster and is it arranged in a banded structure? Also does the gaster alternate between matte and shiny? From the pic the gaster looks pretty shiny and hairless.

Also pics of the workers would be good, I wonder if they share the same characteristics of the queens.

Yup! I can get decent pics. Gaster means abdomen right?

Correct.

These might be the undescribed C. modoc nurbs has been goin after, could you post pics of the workers too?

Yeah it would seem so. All of these share the exact same features as the first queen pictured right? Because the original queen of the ID threat still seems abnormally shiny and hairless to me.

 

These new pics are undeniably C. modoc.

The newer pics seem to show them as matte black, and the queen seems to have a hairy or banded gaster. Could you get pictures of the colony with workers with the same quality as the queen? It would really help to compare the two.
