In a study of a pair of mounted specimens in 2005, Kristofer M. Helgen and Don E. Wilson came to the conclusion that there are morphological differences between the Tres Marias raccoon and the subspecies Procyon lotor hernandezii of the common raccoon found on the Mexican mainland, but that they are not large enough to justify the classification as distinct species.
