Guyana

The following 341 valid species and subspecies of ants are known to occur in Guyana. 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 Guyana ants.
