Members of the genus Dorymyrmex, similar to many other dolichoderine ants, have thin and somewhat flexible integument. They can be differentiated from other dolichoderine ants by the propodeum being pyrimid or cone shaped (on dorsum); the presence of a small psammophore; and the third maxillary palp being as long as the fourth and fifth segments combined. They typically make colonies in the soil in open areas, and often have distinctive crater-like mounds (see the photo above). They are predaceous and often litter their mounds with the bodies of other species of slain ants. Similar to other dolichoderines, they emit an unpleasant odor.
