Recent studies on the digenean fauna at the White and Barents Seas have shown that there are more species than previously thought. These data are emerging in a series of publications, and we suggest to summarize them in a form that is convenient for practical use. Here we provide a guide that covers the 11 species from the family Notocotylidae that we have recorded in the intertidal gastropods Ecrobia ventrosa , Peringia ulvae , Littorina spp. and Onoba aculeus . We recap brief descriptions of rediae and cercariae, documented host and geographic range, though for several species the information is incomplete. We also refer to the DNA barcodes from GenBank, including the new ones. For the better usability, we include hints on the mollusc identification and explain how to deal with the parasites (field and lab procedures).
