Its logispinosus group, but there are some discrepancies with the ID of Temnothorax for it to be rugulatus. 1) rugulatus is described as slow moving, this species was fairly fast; 2) rugulatus is described as only inhabiting areas near pinon trees, this colony was found under a pine tree [put into an acorn later]; 3) rugulatus is not polygynous with macrogynes, only microgynes who are often related, these two macro gynes are not micro gynes for sure; 4) the queens of rugulatus are usually red or orange, these queens are definately black. For all of these reasons I believe this is either a new species or subspecies related to rugulatus, or a locally distinct population.
