Aphaenogaster sp.

Thank you, that gives me a great start. If anyone else scan help with further define this species i would appreciate it!

[Californian Anter]

Maybe Aphaenogaster Rudis? Don't trust me on this one; it's just a guess.

[Nathant2131]

Definitely Aphaenogaster sp.

Thanks, your guess is better than mine I'll do some more research on what the differences are and see if I can look for specific traits

Look on ant wiki for a key. This genus often needs a fairly extensive ID.

I second A. rudis. Looks more like it than either fulva or picea anyway.

[Canadian anter]

It's either Aphaenogaster rudis or Aphaenogaster fulva. I can guarantee it's not picea 

[Salmon]

Fulva usually has a more orangey colored gaster. Also, the ends of fulva's antennae are paler. I can't quite make it out in the picture but there doesn't seem to be a significant color difference in the antennae.

[Nathant2131]

Yes not picea. Theire last 4 antennal segments would be differently colored than the rest.

[MikeMc]

Here is another, blocky, but better color shot.

 

[Salmon]

Gaster definitely doesn't look like fulva, antennae don't seem to.
