Taxonomy
The taxonomic status of certain species in the genus Radix has been disputed. Remigio reported sequence divergence within the 16S mitochondrial gene of Radix peregra and Radix ovata. Furthermore, the shell morphology and alloenzyme data indicated that Radix peregra and Radix ovata are distinct.
In contrast, Bargues et al. considered on the basis of ITS-2 sequence analysis, that R. peregra, R. ovata, and R. balthica are in fact a conspecific species.
