I know this is a Crematogaster sp, but Antmaps.org list 2 possibilities and I don't know the differences. She is either C.lineolata or C.cerasi. Unless that website doesn't have a full list. I caught the queen about a year and a half ago, and figure I would finally post an ID request with some photographs of a dead worker.
