Source-derived summary

Incilius tacanensis, also known as the Volcan Tacana toad, is a species of toad in the family Bufonidae. It is found in western Guatemala and eastern Chiapas (Mexico). Its name refers to Volcán Tacaná, its type locality. Its natural habitat is premontane tropical forest. It is assumed to be a stream breeder. It is a rare species threatened by habitat loss, and potentially, chytridiomycosis.

Taxonomy

Incilius tacanensis was formally described as Bufo tacanensis by P. W. Smith in 1952 based on a specimen collected from Volcán Tacaná in Chiapas, Mexico. It was subsequently moved to the genus Cranopsis (later renamed Ollotis) in 2006, before being transferred to the current genus Incilius in 2009. It has the common name Volcan Tacana toad.

Description

Preserved individuals have dull brown dorsal coloration with dark brown lateral stripes following the lateral tubercles.

Editorial summary

This brief starts where responsible research should: with the source description of “Incilius tacanensis” as species of amphibian. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1952, 2006, 2009—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Incilius, tacanensis and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of amphibian. Its deeper value depends on whether names, dates, institutions and citations support that framing.

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 31, 2026. The linked authority identifier is Q21965824. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1952, 2006 and 2009.

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

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