Source-derived summary

Callimedusa duellmani is a species of frog in the subfamily Phyllomedusinae. It is endemic to Peru and is only known from its type locality near Balzapata, upper Chiriaco River, in the Department of Amazonas. The specific name duellmani honors William E. Duellman, an American herpetologist. Common name purple and orange leaf frog (also spelled purple-and-orange leaf frog) has been proposed for it.

Description

The type series consists of two adult males measuring 52 and 54 mm (2.0 and 2.1 in) in snout–vent length. The snout is short and acutely rounded in dorsal view, sloping when viewed laterally. The tympanum is distinct. The fingers have discs of moderate size but no webbing. The toes have discs that are slightly longer than the finger ones; webbing is absent. Dorsal coloration is green.

Editorial summary

Begin with the source’s own compact description: “Callimedusa duellmani” is species of amphibian. The dossier treats that line as a proposition to test through Callimedusa, duellmani 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 130-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, Callimedusa, duellmani and species is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of amphibian” 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 Aug 10, 2026. The linked authority identifier is Q2700270. 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.
