Knight-Jones et al. (2017) investigate specimens of Pseudopotamilla reniformis from various locations in Europe, restrict the distribution of Pseudopotamilla reniformis to cold northern waters and re-instate Pseudopotamilla saxicava (Quatrefages 1866) for specimens from temperate and tropical waters, including the Mediterranean, noting that the description of Pseudopotamilla reniformis by Fauvel (1927) contains figures of both Pseudopotamilla reniformis and Pseudopotamilla saxicava . Greek records of Pseudopotamilla reniformis probably belong to Pseudopotamilla saxicava .
