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. [2]
These are narrow-bodied slugs up to 8 centimeters long. The mantle covers less than a third of the body length. They are cream-colored to brown or black, usually with at least two longitudinal stripes along the mantle. The sole of the foot is lightest in the middle. The penis is short compared to those of Limax , and in shape it may be "tubular, baggy, or claviform" (club-shaped). [2] The mucus is watery. [2]
Many species live in mountain habitat, where they can be found on trees and rocks and feed on lichens. [2] Other species (in particular those placed by some authorities in the genus Ambigolimax) are synanthropic and invasive.
There are about 18 species in the genus. Currently (2022) authorities disagree whether to split off some species into the genus Ambigolimax , as some phylogenies based on DNA sequences suggest is appropriate. [3] The following list defines Lehmannia in the broad sense (sensu lato), but indicates which species have been placed in Ambigolimax: [4] [3]
Note that the name Lehmannia nyctelia (= Ambigolimax nyctelius ) is no longer valid. The species originally given the species name is in the genus Letourneuxia , but the name has been mistakenly applied to three of the species listed above (L. carpatica, A. parvipenis and A. waterstoni). [3]
Limax is a genus of air-breathing land slugs in the terrestrial pulmonate gastropod mollusk family Limacidae.
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.
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.
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.
Deroceras invadens is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Agriolimacidae. Until 2011, this widely distributed species was known as Deroceras panormitanum, and earlier as Deroceras caruanae or Agriolimax caruanae, but Reise et al. (2011) showed that these names refer to a distinct species of similar external appearance known at that time only from Sicily and Malta. Consequently, although the more widespread species was already well known, it then had to be redescribed under the new name of D. invadens. Genetic evidence has indicated that D. invadens is native in southern Italy, including parts of Sicily, and possibly parts of central Italy. Elsewhere it has been introduced, predominantly within the last 100 years, but its spread has been constrained by cold winter temperatures.
Limax doriae, common name Doria's slug, is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusk in the family Limacidae, the keelback slugs.
Ariunculus is a genus of air-breathing land slugs in the family Arionidae, the roundback slugs. Sometimes it has been considered as a subgenus of Arion, and sometimes the subgenus Ichnusarion has been raised to generic rank.
Mario Lessona was an Italian zoologist and malacologist. He was the son of the prominent natural scientist and senator Michele Lessona and his wife Adele Masi Lessona, who was very much involved in her husband's work, particularly in making translations. A son of Adele Lessona by an earlier marriage was the painter and malacologist Carlo Pollonera, with whom Mario published a monograph on Italian slugs. Mario also coauthored various scientific works with his brother-in-law, the zoologist and senator Lorenzo Camerano.
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.
Letourneuxia nyctelia is a species of terrestrial slug, a gastropod mollusc, belonging to the family Arionidae.
Ariunculus isselii is a species of terrestrial slug belonging to the family Arionidae. Previously it has been placed in the genus Arion or in its own genus Ichnusarion; the latter is more often treated as a subgenus.
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.
