Distribution
Distribution of Limacidae is Holarctic,[1] this include: Nearctic, western Palearctic and eastern Palearctic.[4]
Agriolimacidae is the largest slug family, some are introduced all over the world, synanthropes are often severe pests.[1]
This view of the right side of Deroceras praecox clearly shows the position of its pneumostome.
Anatomy
Most slugs in the family Agriolimacidae are rather small; only a few (in the genera Mesolimax and Krynickillus) are larger. Most are not more than 50 mm long.[1] The mantle is usually large, occupying approximately 1/3 of the entire body length, situated in the anterior part of the body.[1] The pneumostome is clearly postmedial.[1] The surface of the mantle in living slugs is covered in concentric, mobile wrinkles.[1] In addition sometimes there is a shallow, poorly defined groove which runs above the pneumostome on the right side, not passing to the left.[1]
The penis is short, usually bag-shaped, often with external appendages, inside with different stimulatory organs.[1] No tubular membrane encircles the penis and vas deferens.[1] The penis retractor muscle is situated beside the right tentacle.[1]
In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).[5]
