The following 78 genera and 792 species and 18 subspecies of ants are known to occur in the United States. Ants from Hawaii (introduced) are on a separate list. 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 United States ants.

Those who have specimen records that expand this list are encouraged to submit this information in the discussion section of the United States Ants web page. Please advise if any corrections are warranted.

An overview of the fauna can be found at Ants of North America.

Uncertain species

The following species were described from the United States but their true identities are currently unknown.

Previous Records

  • Myrmelachista ramulorum Wheeler, W.M., 1908: Found in Polk City, Polk County, Florida (Smith 1979) but apparently no longer present (Deyrup, Davis & Cover, 2000).
  • Myrmica ruginodis Nylander, 1846: Several quarantine interceptions in New York and Washington, D.C. in the early 1900's, but no known recent records.
  • Plagiolepis alluaudi Emery, 1894: Single record from Catalina Island, California but no evidence it is currently present.
