Hypoponera inexorata is an orangish colored ponerine ant approximately 2 mm in total length. It can be separated from our other species of Hypoponera found in this region by the shape of the mandibles, which are sinuate along the outer border (concave laterally) and the color of mature individuals, which is much yellower or lighter, rather than dark brown to blackish-brown.

This species has recently been collected in Black Belt Prairie remnants in MS. Colonies have been found underneath the soil by random digging. At least one colony has been found underneath an imported fire ant colony (Pers. Comm. JoVonn G. Hill).
