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.
Distribution
[edit]The distribution of the family Limacidae is the western Palearctic.[4] There are 28 species of Limacidae in Russia and adjacent countries.[5]
Cytology
[edit]In this family, the number of haploid chromosomes lies between 21 and 25 and also lies between 31 and 35 (according to the values in this table).[6]
Taxonomy
[edit]2002 taxonomy
[edit]Zhiltsov & Schileyko (2002)[7] elevated the subfamily Bielziinae to family level, Bielziidae, based on the morphology of the reproductive system of Bielzia coerulans.[7]
2005 taxonomy
[edit]The following two subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005):
- subfamily Limacinae Lamarck, 1801 - synonyms: Limacopsidae Gerhardt, 1935;[8] Bielziinae I. M. Likharev & Wiktor, 1980
- subfamily Eumilacinae I. M. Likharev & Wiktor, 1980[9]
Genera
[edit]Genera in the family Limacidae include:
subfamily Limacinae
- Limax Linnaeus, 1758[5] - type genus of the family Limacidae
- Limacus Lehmann, 1864; sometimes considered a subgenus of Limax
- Bielzia Clessin, 1887 - with the only species Bielzia coerulans M. Bielz, 1851. Some authors, for example Russian malacologists,[5] classify genus Bielzia within separate family Limacopsidae.[5]
- Caspilimax P. Hesse, 1926[5]
- Caucasolimax Likharev et Wiktor, 1980[5]
- Gigantomilax O. Boettger, 1883[5]
- Gigantomilax csikii Soós, 1924
- Gigantomilax lederi (Boettger, 1883)
- Gigantomilax majoricensis (Heynemann, 1863)[10]
- Lehmannia Heynemann, 1862[5]
- Ambigolimax Pollonera, 1887,;[11] sometimes considered a subgenus of Lehmannia
- Limacopsis Simroth, 1888
- Malacolimax Malm, 1868[5]
- Turcomilax Simroth, 1901[5]
subfamily Eumilacinae
- Eumilax O. Boettger, 1881 - type genus of the subfamily Eumilacinae
- Eumilax brandti (Martens, 1880)
- Metalimax Simroth, 1896
