Deroceras juranum is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Agriolimacidae.

Later the same coloration was found in Austrian populations by Jordaens et al. (1998)[2] and in other species of Deroceras by Reise & Hutchinson (2001).

Hutchinson & Reise (2009)[6] later realised that what had been considered Deroceras rodnae was actually two species with radically different mating behaviours and consistent, although subtle, differences in morphology.

[4] Identifications to species level require dissection: illustrations of the genitalia are depicted in work by Hutchinson & Reise (2009).

[6] Hutchinson & Reise (2009)[6] confirmed that, besides the type locality in Jura Mountains of Switzerland, other populations in the Swiss Jura Mountains, Germany, Austria and the Czech Republic were Deroceras juranum.
