Fig. 16 in Phyllidiidae (Nudibranchia, Heterobranchia, Gastropoda): an integrative taxonomic approach including chemical analyses

Fig. 16 Phylogeny of Phyllidiidae and chemical analysis of 70 preserved specimens from three genera (Phyllidia, Phyllidiopsis, and Phyllidiella) and 19 species. a Coloured clusters were obtained with classical or feature-based molecular networking and depict families of secondary metabolites characteristic for certain clades, e.g., brominated alkaloids for the genus Phyllidia, amphilectene-type diterpenes for P. coelestis and P. elegans, kalihinol-type diterpenes for P. rudmani, as well less specific secondary metabolites (sesquiterpene isonitriles and derivatives) that were detected throughout the Phyllidiidae. The chemical structures were established either with NMR after compound isolation, or were assigned based on HR-LCMS/MS
