Acromyrmex striatus
''Acromyrmex striatus'' is a species of the leaf-cutter ants found in the Neotropics.〔Cristiano, M., Cardoso, D., & Fernandes-Salomão, T. (2013). Cytogenetic and molecular analyses reveal a divergence between ''Acromyrmex striatus'' (Roger, 1863) and other congeneric species: Taxonomic Implications. PLoS ONE 8(3), 1-9. doi:10.1371/journal.pone.0059784〕
It is a member of the subfamily Myrmicinae, and within the tribe Attini. As an attine, ''Acromyrmex striatus'' forages for vegetation that will be applied to the fungal garden, typical in all leaf-cutting species.〔Benedito C., L. (2005). Vegetable resources used by ''Acromyrmex striatus'' (Roger) (Hymenoptera, Formicidae) in sand dunes at Joaquina Beach, Florianópolis, Santa Catarina State, Brazil. Revista Brasileira De Zoologia, (2), 372.〕 The fungus feeds the mycophagous larvae〔 and queen, while workers are nourished primarily by the sap of cut plants, and very little by the mutualistic fungus making them respectively, phytophagous, and mycophagous.〔 The presence of leaf-cutter ants is so common in the Neotropics, that they are considered to be the main herbivores of these areas.,〔〔Varela, R., & Teresa C., P. (2003). Dispersal of ''Schinus fasciculatus'' seeds by the leaf-cutting ant ''Acromyrmex striatus'' in a shrubland of the dry chaco, Argentina. Journal of Tropical Ecology, (1). 91〕
''A. striatus'' is a polymorphic species, meaning that there are several different sizes of workers, with the largest being 6.5 mm long.〔 This is done to compartmentalize a variety of tasks so they can be done efficiently.

''A. striatus'' is most commonly found in the southern states of Santa Catarina and Rio Grande do Sul in Brazil, and also the countries of Argentina, Uruguay, and Paraguay. At least in Argentina, it prefers nest sites in arid and semi-arid areas, where the sun can shine on it all year.〔Ana, A., & Estela, Q. (2007).

Gayana (Concepción), (2), 203.〕
