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. A few species of ''Procambarus'' have been introduced to regions outside their native range, both in North America and other continents. They are frequently categorized as invasive species, representing a threat to natives, including rarer crayfish species.

Hobbs, Jr., who later erected most of the subgenera fornerly recognised within the genus, in his 1972 monograph ''The subgenera of the crayfish genus ''Procambarus'' (Decapoda: Astacidae)''. However, more recently the subgenera have been eliminated, and while it is recognized that ''Procambarus'' in not monophyletic, later literature does not make further taxonomic changes suggesting that more species sampling is required.
