Non-front-fanged colubroid snakes: A current evidence-based analysis of medical significance

► Non-front-fanged colubroid snakes (NFFC) include taxa known to inflict fatal envenoming. ► There are relatively few well documented cases; those describing bites by ≈ 120 species were analysed. ► NFFC species were classified as Hazard Levels 1 (lethal potential) to 4 (minor local effects only). ► Deficiencies in reported cases and management of medically significant bites by NFFC are discussed.
