Ants of this subgenus are most abundant in the southern portions of the United States. They 

 make their nests in hollow twigs or branches of trees and shrubs, in insect galls and nuts. The 

 soldiers and females have a peculiar cylindrical, truncated head which the soldiers use for 

 blocking the single entrance hole to the nest.
