Socially parasitic ants are usually discernable by their relatively small queens, as ants that start new colonies by infiltrating existing nests do not need large body reserves.  The queen of Aphaenogaster tennesseensis- a temporary nest-founding parasite of several other woodland Aphaenogaster- is scarcely larger than her own workers.
