Genus of gastropods
Radix is a genus of air-breathing freshwater snails, aquatic pulmonate gastropods in the family Lymnaeidae, the pond snails.
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 conspecific.
