Agriolimacidae is a family of small and medium-sized land slugs, or shell-less snails, terrestrial pulmonate gastropod mollusks.

Distribution

Distribution of Limacidae is Holarctic,^[1] this include: Nearctic, western Palearctic and eastern Palearctic.^[5]

Agriolimacidae is the largest slug family, some are introduced all over the world, synanthropes are often severe pests.^[1]

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).^[6]
