Agriolimacidae is a family of small and medium-sized land slugs, or shell-less snails, terrestrial pulmonate gastropod mollusks.
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]
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]
The following two subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005):
