Lehmannia islandica

Lehmannia islandica is a species of air-breathing land slug, a shell-less pulmonate gastropod mollusk in the family Limacidae. It is endemic to Iceland and listed as "Data Deficient" in the IUCN red list due to a lack of detailed distribution data and overlap with the similar species Lehmannia marginata.

Description
The species is occasionally considered a synonym of Lehmannia marginata but is smaller and exhibits a different penis structure being "thickened in its distal section, with a long and pointed flagellum". Like other limacids, these slugs are slim with a pointed tail, and the pneumostome lies is the posterior half of the mantle. The length is reportedly 20 mm.
