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):
Genera within the family Agriolimacidae include:
subfamily Agriolimacinae

Deroceras invadens is a species of air-breathing land slug, a terrestrial pulmonate gastropod mollusc in the family Agriolimacidae. Until 2011, this widely distributed species was known as Deroceras panormitanum, and earlier as Deroceras caruanae or Agriolimax caruanae, but Reise et al. (2011) showed that these names refer to a distinct species of similar external appearance known at that time only from Sicily and Malta. Consequently, although the more widespread species was already well known, it then had to be redescribed under the new name of D. invadens. Genetic evidence has indicated that D. invadens is native in southern Italy, including parts of Sicily, and possibly parts of central Italy. Elsewhere it has been introduced, predominantly within the last 100 years, but its spread has been constrained by cold winter temperatures.
