Harpegnathos

Harpegnathos is a small ponerine genus of ants found in South and Southeast Asia. They are notable for their jumping ability, complex colony structure, and large to very large workers easily identifiable by their long mandibles and large eyes.

Jerdon in 1851 to house the single species Harpegnathos saltator, found in India. Believing that the name was unavailable due to homonymy, Smith (1858) incorrectly erected the unnecessary replacement name Drepanognathus (now a synonym of Harpegnathos). For some time, both names were used in publications by other authors until the original name was restored. The most recent species was described in 1963, making the total number of Harpegnathos species seven, with an additional four described subspecies. The genus is closely related to the other genera in its tribe, Ponerini, and is probably a sister to all Ponerini.
