This subfamily is the predominant group of ants in North America, most common in the north and in the mountains with their numbers decreasing rapidly toward the southern part of the United States. They are recognized by the single segmented pedicel, lack of a constriction between the first and second gastric segments, and the round acidopore, usually with a circle of hairs.
