Classification provided by the World Register of Marine Species (WoRMS). [1760259<\/a>]<\/p><\/div>Taxonomic note<\/strong>: The taxonomic history of Doris berghi<\/em> is complex and represents a recent example of pseudocrypticism within Mediterranean Dorididae. The species was originally described by Vayssi\u00e8re in 1901 as Aldisa berghi<\/em>, based on specimens collected from the Gulf of Marseille. Subsequently, it was regarded as a synonym of Doris ocelligera<\/em> (Bergh, 1881), mainly due to external similarities and in the absence of molecular data. For decades, the yellowish and bluish specimens attributed to Doris ocelligera<\/em> were interpreted as simple intraspecific colour variations. However, the molecular and morphoanatomical study conducted by Renau, Salvador and Moles (2024) demonstrated that both morphotypes actually correspond to distinct species. Through the combined analysis of the COI, 16S and H3 markers, the authors recovered two clearly differentiated lineages, with genetic divergences consistent with species-level separation. Consequently, Aldisa berghi<\/em> was taxonomically resurrected and transferred again to the genus Doris<\/em>, establishing the valid combination Doris berghi<\/em> comb. rest. The study also concluded that D. berghi<\/em> and D. ocelligera<\/em> are sympatric species inhabiting the north-eastern Atlantic and western Mediterranean, distinguishable both molecularly and by external and anatomical characters.<\/p>\n
