Leptothorax is a large genus of small ants with mainly Holarctic distribution. The genus is notable for its widespread social parasitism, i.e. they are dependent on the help of workers from other ant species during a part or the whole of their life cycles.[citation needed]

Closely related genera are Cardiocondyla, Stereomyrmex and Romblonella.[2]
