Trachymyrmex

is a fungus-growing ant intermediate in behavior and morphology between the smaller attines (such as Cyphomyrmex) and the leaf-cutting genera Atta and Acromyrmex. They feed on a subterranean fungus that they cultivate with bits of plant debris and other detritus. Like the other fungus-growers, Trachymyrmex is found only in the Americas.

Trachymyrmex septentrionalis. Trachymyrmex are the closest relatives of the larger leafcutting ants. While they normally use dead vegetative debris to cultivate their fungus, these ants will sometimes use living plant matter.
