Subgenus "Ortmannicus" is the most widespread, with the range of "Procambarus acutus" extending as far north as the Great Lakes and New England, as well as south into northeastern Mexico; the subgenus "Girardella" also extends from the Great Lakes to Mexico, but is distributed further west than "Ortmannicus". "Scapulicambarus" and "Pennides" are widespread in the southeastern United States, where "Remoticambarus" also lives, further west (Texas and Louisiana) than "Leconticambarus" which is centered on Florida and neighboring states. The subgenus "Austrocambarus" has the most southerly distribution, being found in Cuba and parts of Central America from Mexico to Belize, Guatemala and Honduras. The other subgenera are more restricted in their distributions, including three endemic to central Mexico, and six endemic to small areas in the United States.
