Vancouver/Washington/USA - 9/28/16

Found a small colony while walking today, the shape of the chamber made it easy to collect all of the workers, larva, and pupae present. There were 12 workers, a very small batch of eggs, a few larvae, and a single pupae. Colony was under an artificial log. A spider had made it's home right next to them and had clearly been enjoying itself based on the handful of ants in it's web. Any help with identification appreciated.

Remember measurements. ;)

Looks like Tetramorium sp. E, but I wouldn't mind more pictures of the workers.

Figures I forgot the measurements. The queen is ~7-8mm. Might be a moment on more pictures, trying to get them to calm down.

Alrighty, here are some more photos. None came out amazing due to the enclosure. Use the imgur link if you want to be able to zoom a bit.

Thanks! Tetramorium. I wanted to make sure they were not somehow Aphaenogaster.

Are you sure they aren't different species?
While I agree that the workers are tetramorium, queen looks like aphaenogaster

...If they are that would explain why the workers killed her, but not why I found them all in the same chamber... Is it possible she was a parasite queen?

There are no parasitic aphaenogaster or tetramorium in northwest America and southwest Canada
