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)[2] 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.
