Argentina



Gary D. Alpert: Museum of Comparative Zoology, Harvard University

The following 762 valid species and subspecies of ants are known to occur in Argentina. Unidentified and undescribed species will be added to this list as identifications are verified and taxonomic revisions are published. This species list is based upon the effort of many ant collectors as well as myrmecologists who have published on the taxonomy of Argentinian ants. Those who have specimen records that expand this list are encouraged to submit this information in the discussion section of the Argentinian Ants web page. Please advise if any corrections are warranted.
