Bayesian and maximum likelihood phylograms were inferred based on the mitochondrial genes cytochrome <em>c</em> oxidase subunit I (COI) and 16S ribosomal RNA, and the nuclear gene histone H3. We used the automatic barcode gap discovery method to aid in species delimitation. COI genetic uncorrected p-distances were estimated between and within species. Animals were dissected and the reproductive system, radulae and labial cuticles were examined; scanning electron microscopy was employed to study ultrastructural elements of anatomical characters. The results revealed the presence of a new species (<em>Jorunna artsdatabankia</em> n. sp.) and a possible case of incipient speciation in <em>J. tomentosa</em> with our COI data indicating the presence of two morphoanatomically indistinct lineages that are separated from each other by distances of 3.2–5.0%. The genetic distance between <em>J. artsdatabankia</em> n. sp. and its sister species <em>J. tomentosa</em> was 9.0–12.3%; the former species is characterized by a plain white to yellow background colour with irregularly placed small brown spots, smooth radular teeth and a longer vas deferens, wider vagina and a longer copulatory spine (up to 600 μm longer) than the latter. A diagnostic comparison of all species of European <em>Jorunna</em> is included, as well as a discussion of the assignment of <em>J. lemchei</em> to the genus <em>Gargamella</em>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The genus <i>Jorunna</i> (Nudibranchia: Discodorididae) in Europe: a new species and a possible case of incipient speciation","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-01 01:32:15.020233","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-12-20","DateCreate":"2021-12-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000709559900001","VABBcode":null,"OpenAcc":0,"DOI":"10.1093/mollus/eyab028"},"refs":null,"anarec":{"AnaID":348355,"PubliDate":2021,"Pagination":"eyab028","XtraPublOfAnaID":null,"ISBN":null,"Volume":"87","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43084,"SerRR":"Journal of Molluscan Studies.
