Veronicellid slugs are considered the most important intermediate hosts of Angiostrongylus costaricensis, an intra-arterial nematode of rodents. Studies undertaken in three localities in southern Brazil led to identification of molluscs other than veronicellid slugs as hosts of A. costaricensis: Limax maximus, Limax flavus and Bradybaena similaris. These data indicate a low host specificity of larval stages of A. costaricensis, as it has been reported to other congeneric species.

Key words: Angiostrongylus costaricensis; Limax maximus; Limax flavus; Bradybaena similaris; Megalobulimus abbreviatus; abdominal angiostrongyliasis; veronicellid slugs
