Need help w/ Identification 1

[JonahH]

Caught this ant in Greenbrier County, WV in an old wooden building on August 8, 2015 at about 1PM on an overcast day. Fairly large, maybe 5/8cm? Found a large amount of them together, all winged. Couldn't tell any difference in the gaster of different ants so I figured they were all queens since it is a fairly large gaster.

Any ideas about species? Am I right that it's a nuptial queen ant?

Yes they were swarming, I captured a dozen or so and a few have broken off their wings but most have not.

I caught queens with and without wings. 1 of my queens has not removed her wings yet, but she has a few eggs.

Other queens I caught had already shed there wings and 1 shed her wings after a few days in her test tube.

I'm almost positive this is Crematogaster. It is hard to tell because her wings cover up most of her body. This is definitely a nuptial flight queen. Whether she is fertile or not idk.

Crematogaster sp.
Can you make a photo from the side?
