Radix is a genus of air-breathing freshwater snails, aquatic pulmonate gastropods in the family Lymnaeidae, the pond snails. [2]
The genus Radix has a Palaearctic distribution.[3]
Phylogeny
Correa et al. (2010) confirmed that the placement of these species within the genus Radix reflected their phylogenetic relationship.[4] A cladogram showing phylogenic relations of species in the genus Radix:[4]

The haploid number of chromosomes of all species in the genus Radix is 17 (n=17).[4]
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.[5] Furthermore, the shell morphology and alloenzyme data indicated that Radix peregra and Radix ovata are distinct.[6][7]
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.[8]
