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.

Jumping Ants belongs to the Ponerinae subfamily, which is notable for being different from other subfamilies of ants because they are considered to be more primitive, meaning they have more common characteristics with their wasp ancestors. They are also known for combining simple social organization with a high diversity of morphological and behavioral trait

Spiny ants belong to the Formicinae sub-family and the Polyrhachis genus. They are the far away cousins of our worldwide beloved Carpenter Ants.

Polyrhachis is a genus of formicine ants found in the Old World with over 600 species. The genus is yet to be fully understood and described because it is one of the most ecologically diverse ant genera in the world. It contains so many varied species which span so many different types of habitats including mangrove, soil and tree-dwellers.

They can be easily be identified due to the big spikes most workers showcase as a defensive mechanism against predators.
