Scarlet Kingsnake
Lampropeltis elapsoides (Holbrook, 1838)
lam-proh-PEL-tis — ee-lap-SOY-des

SSAR 9th Edition Comments:
The recognition of L. elapsoides as a species was confirmed in a large multilocus study with many individuals sampled by Ruane et al. (2014, Systematic Biology 63: 231–250) and further evaluated and supported with genomic analyses in Burbrink et al. (2022, Systematic Biology 71: 839–858); see additional comments under L. triangulum.
