[2][3] Leptogenys is the most diverse ponerine ant genus in the world; it is widespread throughout tropical and subtropical regions and there are over 260[1] extant species described.

The genus has attracted attention due to its wide variety of social organizations and colony structures as well as its remarkably diverse range of behaviors.

The worker caste of the genus can be distinguished largely by the distinct pectinate ventral margin of the tarsal claws.

[4] The taxonomic history of the genus Leptogenys includes several junior synonyms as a result of the remarkable morphological diversity in the group.

Leptogenys now includes the following junior synonyms: Prionogenys, Lobopelta, Odontopelta, Machaerogenys, Dorylozelus, and Microbolbos.
