Source-derived summary

The southern marbled newt or pygmy marbled newt (Triturus pygmaeus) is a species of salamander in the family Salamandridae. It is found in Portugal and Spain. Its natural habitats are temperate forests, Mediterranean-type shrubby vegetation, rivers, intermittent rivers, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, rural gardens, water storage areas, ponds, open excavations, irrigated land, canals and ditches. It is threatened by habitat loss.

Previously thought to be a subspecies of the marbled newt (Triturus marmoratus), it was raised to species level after genetic studies revealed its distinctiveness from the former.

Distribution

The southern marbled newt occurs only in southern Portugal and southwestern Spain, in Mediterranean climate. The Douro–Tagus watershed forms a narrow, northern border to the range of Triturus marmoratus.

Description

The southern marbled newt is similar in appearance to the marbled newt but is smaller, with adults reaching a total length of 13 centimetres (5.1 in) as against the latter's 17 centimetres (6.7 in). The dorsal surface is yellowish-green heavily mottled with irregular patches of dark brown or black, and there is a thin orange line running along the spine from head to tip of tail, although this stripe fades somewhat in adult males. The underparts are creamy-white with dark spots which distinguishes this species from the marbled newt with its dark underparts.

Editorial summary

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

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 216-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, Southern, marbled and newt 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

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 4, 2026. The linked authority identifier is Q1934196. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
