description: Key to species of Puto based on adult males (modified from Miller & Miller 1993)
Notes: We were not able to find characters to distinguish the adult males of Puto yuccae from the winged Puto echinatus from the California Channel Islands or the inland areas of the western US and Mexico. Puto echinatus from coastal California, as described, is associated only with a wingless male but populations on the California Channel Islands and in inland areas of the western USA and Mexico have only been found with associated winged males; see “Discussion” for more information on the taxonomic issues surrounding Puto echinatus.
