In this work, the authors revise 10 pairs of northeastern Atlantic sister cryptic species of the genus Raphitoma Bellardi, 1847 as currently conceived. The species within each pair differ only or mostly in their protoconch morphology, which reflects their larval developmental type (multispiral vs. paucispiral, corresponding to planktotrophic vs. non-planktotrophic development, respectively). Of the ten studied pairs, one (P. histrix/R. pseudohystrix) includes species with almost allochronic ranges; one pair includes species with allopatric ranges (R. oblonga NE Atlantic, R. alleryana Central Mediterranean Sea); the remaining 8 studied pairs include exclusively Mediterranean species. Four species are described as new. New taxa: Raphitoma skylla n. sp., Raphitoma kharybdis n. sp., Raphitoma bartolinorum n. sp., Raphitoma ebreorum n. sp. 77 pp., 65 figs, 3 tabs, br. 4.
