macro pics!

Definitely not Myrmica americana. Could be Myrmicina americana.

what?

[Jonathan21700]

This is Myrmica.

[Nathant2131]

In a walnut?

 

Myrmecina americana (what Salmon probably meant) should be taken into strong consideration, then. I've never heard of a Myrmica that nests in nuts.

 

Edit: I believe I see two pairs of propodeal spines and a barrel-shaped petiole.. If so, definitely Myrmecina americana.

No, I'm pretty sure these are Myrmica sp. Can we get a measurement, though, please? I mean, really? A battery??

If they are Myrmica, we will not be able to identify them to the species through photographs.

Yeah the legs look like they might be too long to be Myrmecina. But if they are Myrmica they certainly aren't M. americana.

The proportions of the head and the size/position of the eyes tell me this is not Myrmecina. You might have trouble finding their second set of propodeal spines as well. Myrmecina are smaller than Myrmica, although we don't have a measurement.

the gaster is spot on and they do have the spines. ill upload some macros i took

[MichiganAnts]

[Batspiderfish]

Myrmecina have two sets of propodeal spines (4 spines total). Myrmica, and many other myrmicine ants have one set of propodeal spines (2 total).

The gaster is not a diagnostic for either of these ants.

[LC3]

These pictures are pretty poor in quality but in the first and second picture of the second post you can see a queen and its mesosoma is clearly covered in lots rugae, as well as being quite slender.

To my knowledge Myrmecina have a smooth back with a wide plate, whereas Myrmica have a slender oval plate covered in rugae. 

 

I say it is Myrmica.

Did we ever successfully ID these ants?

[Nathant2131]

Did we ever successfully ID these ants?

Nope. We need measurements, and better pictures would be ideal.

[MichiganAnts]

they are myrmecina americana and i've already sold them. The buyer agreed that they are myrmecina americana aswell.

[Civz]

If you are so sure, and un willing to hear out the members from whom you requested help, then why post for the ID to begin with? xD Grats on the find though!
