The Veronicellidae, common name the leatherleaf slugs, are a terrestrial family of pulmonate slugs. The herbivorous molluscs occur mainly in the tropical and subtropical areas of America, Asia and Africa. They act as intermediate hosts of the rat lung worm ''Angiostrongylus costaricensis'', and act as a vector for other human diseases. They also cause significant damage to crops. == Description == The dorsal surface of these slugs is entirely covered by the mantle or hyponota. These mollusks have a posterior located anus, eyes on contractile (not retractile) tentacles, and no lung or pulmonary organ. In these aspects they are anatomically distinct from most other types of terrestrial slugs, which typically belong to the order Stylommatophora, and which have a forward located anus, and retractile tentacles. The closely related members of the family Onchidiidae differ from the Veronicellidae by having a pulmonary sac, or lung.〔http://www.palaeos.com/Invertebrates/Molluscs/Pulmonata/Systellommatophora.html Systellommatophora at Palaeos〕〔http://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=78765 Integrated Taxonomic Information System: Veronicellidae〕〔http://animaldiversity.ummz.umich.edu/site/accounts/classification/Veronicellidae.html Univ.
