Biodiversity hotspot in cold waters: a review of the genus Cuthonella with descriptions of seven new species (Mollusca, Nudibranchia)
Korshunova, Tatiana; Sanamyan, Nadezhda P.; Sanamyan, Karen E.; Bakken, Torkild; Lundin, Kennet; Fletcher, Karin; Martynov, Alexander (Peer reviewed; Journal article, 2020)Cuthonella Bergh, 1884 is of one of the most neglected nudibranch groups, with a long history of taxonomic confusion with other aeolidacean genera. Owing to its predominantly Arctic distribution with cold water, its species ... -
Biogeographic patterns of distribution of the mollusc Zelentia ninel (Nudibranchia, Trinchesiidae)
Broms, Fredrik Björn; Bakken, Torkild; Martynov, Alexander; Korshunova, Tatiana (Peer reviewed; Journal article, 2023)In the present contribution we report, for the first time, records of the nudibranch Zelentia ninel from Norway. The species is previously known only from the Barents Sea coast in northern Russia where it was described for ... -
The first consolidation of morphological, molecular, and phylogeographic data for the finely differentiated genus Diaphoreolis (Nudibranchia: Trinchesiidae)
Korshunova, Tatiana; Fletcher, Karin; Bakken, Torkild; Martynov, Alexander (Peer reviewed; Journal article, 2023)We demonstrate the application of the multilevel organismal diversity approach using the example of the nudibranch trinchesiid genus Diaphoreolis. For the first time, fine-scale morphological, genetic, and phylogeographic ... -
Polyphyly of the traditional family Flabellinidae affects a major group of Nudibranchia: aeolidacean taxonomic reassessment with descriptions of several new families, genera, and species (Mollusca, Gastropoda)
Korshunova, Tatiana; Martynov, Alexander; Bakken, Torkild; Evertsen, Jussi; Fletcher, Karin; Mudianta, I Wayan; Saito, Hiroshi; Lundin, Kennet; Schrödl, Michael; Picton, Bernard (Journal article; Peer reviewed, 2017)The Flabellinidae, a heterogeneous assembly of supposedly plesiomorphic to very derived sea slug groups, have not yet been addressed by integrative studies. Here novel material of rarely seen Arctic taxa as well as North ... -
Similar Ones Are Not Related and Vice Versa—New Dendronotus Taxa (Nudibranchia: Dendronotidae) from the North Atlantic Ocean Provide a Platform for Discussion of Global Marine Biodiversity Patterns
Korshunova, Tatiana; Grøtan, Viktor Vasskog; Johnson, Kjetil Breivik; Bakken, Torkild; Picton, Bernard; Martynov, Alexander (Peer reviewed; Journal article, 2023)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 ... -
Species delimitation and phylogeny of Doto (Nudibranchia: Dotidae) from the Northeast Atlantic, with a discussion on food specialization
Martinsson, Svante; Malmberg, Klas; Bakken, Torkild; Korshunova, Tatiana; Martynov, Alexander; Lundin, Kennet (Peer reviewed; Journal article, 2021)The nudibranch genus Doto is taxonomically problematic in particular, and some species are described on the notion of strict monophagy. Here we perform species delimitation on NE Atlantic species, as well as placing them ... -
A synoptic review of the family Dendronotidae (Mollusca: Nudibranchia): a multilevel organismal diversity approach
Korshunova, Tatiana; Bakken, Torkild; Grøtan, Viktor Vasskog; Johnson, Kjetil Breivik; Lundin, Kennet; Martynov, Alexander (Peer reviewed; Journal article, 2020)A synoptic review of the family Dendronotidae is presented based on morphological and molecular data. Three genera are recognized: Dendronotus, Pseudobornella, and Cabangus gen. nov. Two new Dendronotus species are described, ...
