SSAR 9th Edition Comments:
Schrey et al. (2015, Journal of Herpetology 49: 415–419), using mtDNA data, found a genetic, north-South split in mid-peninsular populations. (Boundy, Jeff, Frank T. Burbrink, and Sara Ruane. 2025. Squamata (excluding lizards) – Snakes. Pages 38-54 in Kirsten E. Nicholson (Editor), Scientific and Standard English Names of Amphibians and Reptiles of North America North of Mexico, with Comments Regarding Confidence in Our Understanding, 9th Edition. Society for the Study of Amphibians and Reptiles, Lawrence, Kansas. 87 pp.)
Errata/Changes: Page 52: "north-South" should be "north-south". — (4/10/2025)

Taxonomic Etymology:
A relict species believed to be isolated from other populations.
Tantilla — A diminutive form of Tantillus, itself likely derived from Latin tantus, meaning “so small” or “so little.” The name refers to the small size of these snakes.
relicta — From Latin relictus, meaning “left behind” or “abandoned.” Refers to its relictual distribution—geographically isolated in peninsular Florida, possibly a remnant of a once wider range.
