SSAR 9th Edition Comments:
Following the mtDNA-based phylogeny in Daza et al. (2009, Molecular Phylogenetics and Evolution 53: 653–657), including the unique color pattern of the taxon, Wallach et al. (2014, Snakes of the World: A Catalogue of Living and Extinct Species. CRC Press, Boca Raton, Florida) and Barrio-Amorós (2019, Reptiles & Amphibians 26: 1–15) consider L. septentrionalis to be restricted to its former subspecific concept in northeastern Mexico and southern Texas.
