Source-derived summary

Masticophis flagellum is a species of nonvenomous colubrid snake, commonly referred to as the coachwhip, whip snake or the red racer. It is endemic to the United States and Mexico. Three subspecies are recognized. It is listed as a species of Least Concern by the ICUN.

Editorial summary

The public source identifies “Masticophis flagellum” as species of snake. This brief keeps that definition visible, then builds a research path around Masticophis, flagellum and Species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 46-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Masticophis, flagellum and Species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Masticophis flagellum”, the useful work is to connect “species of snake” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 21, 2026.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
