Source-derived summary

Exosoma lusitanicum, the daffodil leaf beetle, is a species of skeletonizing leaf beetles belonging to the family Chrysomelidae, subfamily Galerucinae.

Etymology

The genus Exosoma is derived from the ancient Greek ἕξω, meaning outside and σῶμα, meaning body. The Latin species name lusitanicus, meaning occurring in Lusitania (Portugal), refers to the area of distribution of this species.

Distribution

This quite common species is found in France, Italy, Spain, Portugal, North Africa (Morocco, Algeria, Tunisia) and in the Near East.

Habitat

These beetles occur in warm-dry areas, both in the plains as well as at an elevation of a thousand meters.

Description

Exosoma lusitanicum can reach a length of 6–8 millimetres (0.24–0.31 in). These small beetles have an elongated, oval and glabrous body. Its pronotum is very finely punctured, convex, and wider than long. Elytra are tight and finely punctured. The basic colour of the pronotum and elytra is shiny red-orange.

Editorial summary

“Exosoma lusitanicum” enters the record as species of beetle. Crown Archives preserves that source wording while asking what Exosoma, lusitanicum and species can confirm, complicate or overturn.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 149-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Exosoma, lusitanicum and species.
Editorial analysis

Why this record matters

“Exosoma lusitanicum” is worth following because a concise public description often conceals a longer documentary argument. Here, Exosoma, lusitanicum and species provides the most credible route into that argument.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 7, 2026. The linked authority identifier is Q148293. None of the 0 selected statements returned an explicit reference.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
