Green Ratsnake
Senticolis triaspis (Cope, 1866)

Current SSAR Comments:
Roth-Monzón et al. (2021, Ichthyology & Herpetology 109: 1026–1035), using morphometric and DNA data, detected a deep, north-south split in Senticolis populations along Mexico’s transverse volcanic province. However, they did not recommend taxonomic changes. See also Dahn et al. (2018, Molecular Phylogenetics and Evolution 129: 214–225).
