Classification provided by the World Register of Marine Species (WoRMS). [1528383<\/a>]<\/p><\/div>Taxonomic note<\/strong>: Furfaro & Mariottini (2021) published “Integrative taxonomy is an evolving field of multidisciplinary studies often utilised to elucidate phylogenetic reconstructions that were poorly understood in the past. The systematics of many taxa have been resolved by combining data from different research approaches, i.e., molecular, ecological, behavioural, morphological and chemical. Regarding molecular analysis, there is currently a search for new genetic markers that could be diagnostic at different taxonomic levels and that can be added to the canonical ones. In marine Heterobranchia, the most widely used mitochondrial markers, COI and 16S, are usually analysed by comparing the primary sequence. The 16S rRNA molecule can be folded into a 2D secondary structure that has been poorly exploited in the past study of heterobranchs, despite 2D molecular analyses being sources of possible diagnostic characters. Comparison of the results from the phylogenetic analyses of a concatenated dataset (the nuclear H3 and the mitochondrial COI and 16S markers) and from the 2D folding structure analyses of the 16S rRNA from the type species of the genera investigated demonstrated the diagnostic power of this RNA molecule to reveal the systematics of four genera belonging to the family Myrrhinidae (Gastropoda, Heterobranchia). The \u201cmolecular morphological\u201d approach to the 16S rRNA revealed to be a powerful tool to delimit at both species and genus taxonomic levels and to be a useful way of recovering information that is usually lost in phylogenetic analyses.” While the validity of the genera Godiva<\/em>, Hermissenda<\/em>, Nanuca<\/em> and Phyllodesmium<\/em> are confirmed, a new genus was necessary and introduced for existing Dondice banyulensis<\/em>: Nemesignis<\/em>.<\/p>\n
