Limacidae, also known by their common name the keelback slugs, are a taxonomic family of medium-sized to very large, air-breathing land slugs, terrestrial pulmonate gastropod molluscs in the superfamily Limacoidea.
Lehmannia is a genus of air-breathing land slugs in the family Limacidae, the keelback slugs. The genus is distributed in Europe and North Africa.
Ambigolimax valentianus is a species of terrestrial slug, a pulmonate gastropod mollusc in the family Limacidae. It has spread very widely around the world, especially in greenhouses, where it can be a pest; in warmer climates it has often then spread outdoors. Comparatively much has been learnt about its life cycle and temperature relations. Dissection is necessary to reliably distinguish it from congeners in regions where these co-occur.
Limacus is a genus of air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Limacidae, the short-keeled slugs.
Letourneuxia is a genus of large air-breathing land slugs, terrestrial pulmonate gastropod mollusks in the family Arionidae, the roundback slugs.
Lehmannia melitensis is a species of air-breathing land slug, a shell-less pulmonate gastropod mollusk in the family Limacidae.
Limax dacampi is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Limacidae, the keelback slugs.
Ambigolimax is a genus of air-breathing land slugs in the family Limacidae, the keelback slugs. There is still ongoing disagreement whether it is more appropriate to consider Ambigolimax as merely a subgenus of Lehmannia; the evidence for splitting them is phylogenetic trees constructed on the basis of DNA sequences.
The name Ambigolimax nyctelius has been used to refer to several species of air-breathing land slugs in the family Limacidae. An article published in 2022 revealed this confusion and furthermore showed that the original description applied to a slug species in a different family. The above names are therefore no longer appropriate and care is need to interpret the meaning of earlier usages.
Ambigolimax parvipenis is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the Limacidae.
Ambigolimax waterstoni is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Limacidae.
Lehmannia carpatica is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Limacidae.
