01Narrative

Arion vejdorskyi or Arion vejdowskyi is a taxon with unclear taxonomic position and probably a synonym for other species.Wiktor, A. 1996. The slugs of the former Yugoslavia (Gastropoda terrestria nuda - Arionidae, Milacidae, Limacidae, Agriolimacidae). - Annales Zoologici 46 (1-2): 1-110. Warszawa, page 16. It was described as a species of air-breathing land slug, a shell-less terrestrial gastropod mollusk in the family Arionidae, the roundback slugs.

05DNA & barcoding77 specimens

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Arion distinctus has left across the world's sequence archives.

Variant network

Each circle is a barcode variant; bigger = more specimens, colour = region. Lines join the most similar variants and the tick marks count the mutations between them — a tight cluster is one “dialect”, a long line a more divergent lineage. Click a circle to list its actual specimens.

Where the DNA of Arion distinctus was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
