Owing to its predominantly Arctic distribution with cold water, its species are difficult to find and to collect, and thus to describe. In this study we revise the genus by presenting molecular and morphological data for a majority of the species, including the type, <jats:italic>C. abyssicola<\/jats:italic> Bergh, 1884. The material is based on a broad geographic sampling throughout the Northern Hemisphere. Particular emphasis is placed on the Kuril Islands, a diversity hotspot for the genus. Seven new species and two subspecies of <jats:italic>Cuthonella<\/jats:italic> are described from the Arctic and North Pacific regions. The number of species of <jats:italic>Cuthonella<\/jats:italic> is thus increased over threefold and now comprises 15 species plus two subspecies instead of five species. This work is the most substantial update of the genus <jats:italic>Cuthonella<\/jats:italic> since its description in 1884. To delineate taxonomic and phylogenetic limits of <jats:italic>Cuthonella<\/jats:italic>-like aeolidaceans, the molecular phylogeny of the wider traditional \u201ctergipedids\u201d is presented and shows that <jats:italic>Cuthonella<\/jats:italic>-like aeolidaceans form a distinct molecular clade as the family Cuthonellidae Miller, 1977, corroborated by reliable morphological apomorphies.<\/jats:p>","DOI":"10.1163\/18759866-bja10017","type":"journal-article","created":{"date-parts":[[2020,12,30]],"date-time":"2020-12-30T22:00:27Z","timestamp":1609365627000},"page":"216-283","source":"Crossref","is-referenced-by-count":21,"title":["Biodiversity hotspot in cold waters: a review of the genus Cuthonella with descriptions of seven new species (Mollusca, Nudibranchia)"],"prefix":"10.1163","volume":"90","author":[{"given":"Tatiana A.","family":"Korshunova","sequence":"first","affiliation":[{"name":"Koltzov Institute of Developmental Biology RAS, 26 Vavilova Str., 119334, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadezhda P.","family":"Sanamyan","sequence":"additional","affiliation":[{"name":"Kamchatka Branch of Pacific Geographical Institute FEB RAS, Partizanskaya Str. 6, 683000 Petropavlovsk-Kamchatsky, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karen E.","family":"Sanamyan","sequence":"additional","affiliation":[{"name":"Kamchatka Branch of Pacific Geographical Institute FEB RAS, Partizanskaya Str. 6, 683000 Petropavlovsk-Kamchatsky, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Torkild","family":"Bakken","sequence":"additional","affiliation":[{"name":"NTNU University Museum, Norwegian University of Science and Technology, NO-7491 Trondheim, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kennet","family":"Lundin","sequence":"additional","affiliation":[{"name":"Gothenburg Natural History Museum, P.O.
