Notes

The ant genus Leptogenys is one of the most diverse and abundant ponerines throughout the tropical and subtropical regions. The genus has attracted attention due to its wide variety of social organizations and colony structures as well as its remarkably diverse range of behaviours.

Leptogenys range from large-eyed epigaeic (living or foraging primarily above ground) species to small-eyed cryptobiotic species that inhabit the soil layers or forage through the leaf litter. Such variation occurs across the geographical distribution of the genus. The maxillosa species-group includes widespread species that have expanded well beyond their native ranges. The worker caste of the genus can be distinguished largely by the distinct pectinate ventral margin of the tarsal claws.
