Harpegnathos

Harpegnathos, from the Greek word harpe, which refers to a curved weapon such as a sickle, and gnathos which refers to jaw. Hence the sickle jaw or curve blade jaw ant. But we normally call them Jumping Ants.

Harpegnathos though they are frequently compared to Myrmecia species from Australia. Their long upward curved mandibles, and remarkably large and prominent eyes, with their elongated thorax instantly identify them.
