We conducted molecular phylogenetic and Phylogeographic analyses of genus Potomida.
Analyses recovered three species: P. littoralis, P. acarnanica, and P. semirugata.
P. littoralis is divided in two mtDNA lineages with shared nuclear haplotypes.
Potomida started radiating during the upper Miocene.
All three species are highly threatened and need an IUCN status update.
