Worker about 7 - 48 th of an inch long, head oblong, nearly smooth, emarginate behind; eyes small; jaws triangular, toothed; thorax but slightly grooved and with two longish spines posteriorly; first abdominal pedicle broadly conic, second rounded; head thorax and legs dark marroon, abdomen blackish.

Warrior nearly 1 / 2 inch long, head very large, nearly smoothed, slightly striated; jaws lancet, shaped, entire; eyes small, somewhat advanced, antennas short, otherwise as in the Worker.

I procured this Ant in the Wynaad where it is not uncommon. The difference between the Worker and the Warrior is greater than in any other Indian species.
