United States: Arizona Nevada New Mexico Utah

Taxonomic Etymology:
Named for its distinctive banding.
Lampropeltis — Derived from the Greek lamprós (λαμπρός, “shiny”) and péltē (πέλτη, “shield”). The name likely refers to the genus’ smooth, glossy scales, which resemble a polished shield.
pyromelana — A color-based morphology descriptor. It is a compound Latinized adjective derived from the Greek roots pyr (πῦρ, “fire”) and melas (μέλας, “black”), literally meaning “fire-black.” The name refers to the species’ bold coloration, in which narrow white bands are bordered by black and red intervals, with red and black dominating the overall pattern. The original description emphasizes this striking pattern: “Fifty to fifty-eight black annuli on an ochraceous white ground, on the body; each anteriorly completely, posteriorly more or less incompletely split by a Vermillion annulus; all extending with irregularities on the belly.”
