Explanation of Names
At the moment this is not a valid subgeneric name, but is still widely used informally to distinguish thief ants from fire ants. Some part of the "Diplo" group as commonly construed may deserve resurrection of the name to incorporate it, with new names to be coined for other lineages within the genus. Most of the diversity is Neotropical, and at present, completely intractable.
Most are subterranean, and are bait-trapped or sifted out of litter or soil. In warmer regions, some are arboreal, living in hollow twigs, galls, bases of epiphytes, or litter accumulated in branch junctions and tree holes.
