Update 1:
This is a Crematogaster sp. I've had for a couple months now. I hibernated her, then took her out at the same time as the Myrmica queen I also have a journal on. I thought she was infertile, as she didn't lay eggs for two whole months, but about 15 days ago she randomly decided to lay a massive clutch of eggs. She's doing really well now, and workers can't be that far off.
