- Аннотация: One new species of the genus Dendronotus (Nudibranchia: Dendronotidae) is described from Norway and Northern Ireland, as well as from the adjacent North Sea, and one new subspecies of Dendronotus arcticus is described from Norway by applying a combination of fine-scale morphological and molecular phylogenetic data. The present case demonstrates multilevel morphological and molecular similarities and differences considering on the one hand a grouping of three similar looking sympatric taxa (D. yrjargul, D. arcticus gartensis n. subsp. and D. keatleyae n. sp.), and on the other hand two different looking apparently allopatric subspecies (D. arcticus arcticus and D. arcticus gartensis n. subsp.). The type species of the genus, D. frondosus, which is the commonest dendronotid in Norway and the United Kingdom, consistently demonstrates substantial molecular and fine-scale morphological differences from D. keatleyae n. sp. Thus, the present example of Dendronotus demonstrates a genuinely multilevel complex of both morphological and molecular similarities and differences. Therefore, the naming of ‘morphodiversity’, contrary to the guidelines of the “integrative taxonomy”, is among the most crucial of aims of taxonomy, from which we will approach a true understanding of “units of life’s diversity”. Any proposals for putative absence of “morphological differences” in reality implies insufficient fine-scale comparison. The present study, apart from providing purely taxonomic information, also provides new data for a broad discussion of global biodiversity patterns.
