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.

Taxonomy

Harpegnathos Harpegnathos

The genus was established by Thomas C. 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.

Colony structure

Harpegnathos has a complex and different colony structure compared to other genera. In the beginning, young winged queens fly out from their natal colony, mate with foreign males and start new colonies independently. What differs from other ants is that, once the short-lived founding queen dies, several daughter workers replace her as reproductives in the colony. It is characteristic of several ponerine species that workers can mate (almost always with foreign males) and store sperm in the spermatheca.

In Harpegnathos saltator, many young workers inbreed with males from the same colony (their brothers). They fight to establish a dominance hierarchy, and a few high-rankers will become reproductives and lay eggs, so-called gamergates. Every year, new winged queens will be reared, and they will disperse and start the process again. The combination of queen and gamergate reproduction results in an increased lifespan of colonies, in theory making them immortal.
