The army ant genus Dorylus, also known as driver ants, safari ants or siafu, are found primarily in central and east Africa,though the range extends to tropical Asia. There are some 70 species presently recognized, though another 60 names are applied at the rank of subspecies.
Unlike the members of the Ecitoninae, they do form anthills, although these are temporary (a few days up to three months). Each colony can contain over 20 million individuals. As in their New World counterparts, there is a soldier class among the workers, which is larger, with a very large head and pincer-like mandibles. They are capable of stinging, but very rarely do so, relying instead on their powerful shearing jaws.
