The genus Radix has a Palaearctic distribution.
Phylogeny
Correa et al. (2010) confirmed that the placement of these species within the genus Radix reflected their phylogenetic relationship. A cladogram showing phylogenic relations of species in the genus Radix:
The haploid number of chromosomes of all species in the genus Radix is 17 (n=17).
Species
The taxonomic status of certain species in the genus Radix has been disputed. Remigio (2002) 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. (2001) considered on the basis of ITS-2 sequence analysis, that R. peregra, R. ovata, and R. balthica are in fact a conspecific species.
Or instead perhaps:
Parasites
Species within the genus Radix are utilized as intermediate hosts by several different trematode species:
