A neotype is designated for Papilio troilus Linnaeus, 1758 from Middleton Place Plantation, Charleston County, South Carolina, United States. A neotype is designated for Papilio ilioneus J.E. Smith, 1797 from Burke County, Georgia. Abbot’s ilioneus figures in Smith are the first published representations of nominotypical Pterourus troilus troilus. Papilio troilus variation texanus Ehrmann, 1900 was described from Houston, Texas. The texanus type is in the Carnegie Museum, Pittsburgh, Pennsylvania, United States. The name texanus was restricted (by original description) to a gray male form and is not subspecifically available under International Code for Zoological Nomenclature (ICZN) article 45.5 or 45.6. This name has occasionally been misapplied subspecifically to populations of troilus from Texas eastward along the Gulf coast to the Atlantic coast of north Florida and southeast Georgia. All populations in these areas are Pterourus troilus troilus. Rothschild & Jordan (1906), Seitz (1924), and Tyler (1994) are examined. Pterourus troilus fakahatcheensis Gatrelle is described from the vicinity of the Fakahatchee Strand, Collier County, Florida. Its range is restricted to the Everglades ecosystem south of Florida Highway 80 at the southern tip of Florida. Pterourus troilus fakahatcheensis is hypothesized to be a peri-Pleistocene relict of the central Florida island or Caribbean faunas. The fakahatcheensis holotype and both neotypes are currently in the Museum of the Hemispheres (MOTH), Goose Creek, South Carolina, United States.
