The slugs - Family of milacidae ( lat. Milacidae) belongs to the order of gastropods .

features

The species in the family are medium to very large with a well developed keel. The mantle shield is relatively short and usually less than a third of the total body length. It does not show a concentric pattern, just fine, irregularly distributed warts. The case is greatly reduced and only flat with an oval outline. It is enclosed by the coat .

distribution

The main focus of the distribution is in south-western Europe. However, some species also occur in Western and Central Europe. Some species have now also been transferred to other continents.

Systematics

The two genera Tandonia and Milax with a total of around 20 species belong to the Kielschnegel family . In the case of the genus Tandonia in particular, it is still unclear whether some species are not identical to one another. The genus Milax is divided by some authors into the two sub-genera Milax (Milax) and Milax (Micromilax) Hesse, 1926.
