Here she is:

12 mm, found in northern Nevada, super dark color, and her gaster is engorged with eggs. Found 4/14/18 under a rock. She hadn't really dug down at all.
I've posted elsewhere a couple of times now, and it seems that people kind of agree that she's probably crematogaster sp. (Some people thought formica as well though.)
I would have thought she was C. Cerasi, but those live over a state away from me.
When those eggs finally make it to being full grown ants, I'll probably try again if this forum doesn't work.
Anyway, thank you for checking this out.
