CommentSubspecies: Elaphe guttata emoryi (Baird & Girard 1853) has been elvated to full species status.

Type species: Coluber guttatus LINNAEUS 1766 is the type species of the genus Pantherophis FITZINGER 1843: 25.

Hybrids: BRÖER (1977) reports a hybrid between E. guttata guttata and E. obsoleta quadrivittata. KREUTZ (2005) reports hybrids between E. guttata and Lampropeltis getulus californiae, between E. guttata and L. pyromelana, and between E. guttata and L. triangulum sinaloae. Bechtel & Mountain (1960) report hybrids between Elaphe guttata and E. obsoleta rossaleni.

Genome: a draft genome of this species has been published by Ullate-Agote et al. 2015.

Synonymy partly after BURBRINK 2002.

Illustration: SCHMDIT (2004) illustrates a striped mutation.

Phylogenetics: see Dahn et al. 2018 for a phylogeny of Lampropeltini, but also see Burbrink et al. 2020, Hillis & Wüster (2021), and Burbrink et al. 2021 for the relationships among obsoletus, alleghaniensis, quadrivittatus, and bairdi.

Habitat: partly arboreal (Harrington et al. 2018). 
EtymologyNamed after Latin guttatus, a, um, ‘spotted, speckled’, in reference to the spotted coloration of this taxon.

The genus name was derived from the Greek words panther, meaning "panther" and ophis, meaning "snake," probably in reference to the spotted and colorful pattern of the type species.
