Dorymyrmex

is a soil-nesting dolichoderine ant abundant in the warmer climates of the New World, particularly in open and arid habitats. Nests of these active, alert insects are usually marked by a characteristic volcano-shaped nest entrance, while the ants themselves can be recognized by a characteristic upward-pointing tooth on the propodeum.
