Incilius pisinnus
species of Amphibia
Incilius pisinnus (common name: Michoacan toad) is a species of "true" toads in the family Bufonidae. It is endemic to Mexico and known from the Tepalcatepec Valley in Michoacán. Prior to its description in 2005, it was mixed with Incilius coccifer and Incilius cycladen. The specific name pisinnus, from the Latin word for "small", refers to the comparatively small size of this species among its close relatives.
Description
Adult males measure 39–51 mm (1.5–2.0 in) and adult females 55–62 mm (2.2–2.4 in) in snout–vent length. The body is robust. The snout is pointed in dorsal view and rounded in profile. The tympanum is distinct. The fingers are short, slender, and have no webbing nor fringes, whereas the toes have some webbing and the inner toes have also lateral fringes. The canthal, supraorbital, supratympanic, postorbital, preorbital, pretympanic, and supralabial crests are present.
Begin with the source’s own compact description: “Incilius pisinnus” is species of Amphibia. The dossier treats that line as a proposition to test through Incilius, pisinnus and species, not as a finished interpretation.
Why this record matters
The phrase “species of Amphibia” 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q28031932. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005.
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.
