Resumen:
Leaf-Cutting Ants (LCA) belonging to the genera Atta and Acromyrmex only inhabit the American continent. They are characterized by cutting fragments of leaves and flowers and using them as substrate for the cultivation of a basidiomycete fungus on which they feed. The aim of this work was reconstruct a phylogeny of LCA using molecular data in order to better understand how the leaf cutting habits have evolved in this ants. Reconstruction of the types of cutting habit revealed that dicotyledonous cutting would be the ancestral habit of all LCA, while grass cutting appeared at least five times independently. The habit of cutting both dicotyledons and grasses would be a derived habit.
