Radix (gastropod) explained

Radix is a genus of air-breathing freshwater snails, aquatic pulmonate gastropods in the family Lymnaeidae, the pond snails.[1]

The genus Radix has a Palaearctic distribution.[2]

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:[3]

The haploid number of chromosomes of all species in the genus Radix is 17 (n=17).[3]

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.[4] Furthermore, the shell morphology and alloenzyme data indicated that Radix peregra and Radix ovata are distinct.[5] [6]

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.[7]

Or instead perhaps:

Taxa inquirenda:
Species brought into synonymy:

Parasites

Species within the genus Radix are utilized as intermediate hosts by several different trematode species:
