Source-derived summary

Xenodon merremii, also known commonly as Wagler's snake, is a species of snake in the subfamily Dipsadinae of the family Colubridae. The species is endemic to South America and is widespread in the eastern half of the continent.

Geographic range

Xenodon merremii occurs in Venezuela, Guyana, Suriname, French Guiana, Brazil, Bolivia, Paraguay, Uruguay, and northern Argentina.

Habitat

The preferred natural habitat of Xenodon merremii is open areas of savanna and shrubland, at elevations from sea level to 2,000 m (6,600 ft), but it is also common in disturbed habitats.

Etymology

The specific name, merremii, is in honor of German herpetologist Blasius Merrem.

Description

Adults of Xenodon merremii are usually 1 m (39 in) or less in total length (tail included). Its color pattern is very variable. Some "red phase" specimens are a uniform reddish tan. Other specimens are pale brown dorsally, with broad dark-brown crossbands, which are edged with black, and are narrower or interrupted in the middle. The latter color pattern resembles that of the venomous snake Bothrops alternatus.

Editorial summary

Begin with the source’s own compact description: “Xenodon merremii” is species of reptile. The dossier treats that line as a proposition to test through Xenodon, merremii and species, not as a finished interpretation.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current 170-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Xenodon, merremii and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of reptile” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 17, 2026. The linked authority identifier is Q58206874. None of the 0 selected statements returned an explicit reference.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
