World’s northenmost and rarely observed Nudibranchs: three new Onchidoridid species (Gastropoda: Doridida) from Russian seas

The world’s most northern species of the nudibranch genus Adalaria rossica sp. nov. from Franz Josef Land and a new species of Onchidoris expectata sp. nov. from the north-west Pacific Matua Island (Kurile Islands) are described. Prior to this study the nudibranch fauna from Franz Josef Land was rep...

Description
Summary:The world’s most northern species of the nudibranch genus Adalaria rossica sp. nov. from Franz Josef Land and a new species of Onchidoris expectata sp. nov. from the north-west Pacific Matua Island (Kurile Islands) are described. Prior to this study the nudibranch fauna from Franz Josef Land was represented only by two common North Atlantic species. Molecular taxonomic data were not applied for the Franz Josef Land nudibranchs previously. Nudibranchs of Matua Island have never been investigated. Furthermore, a new North Pacific taxon, Adalaria ultima sp. nov., is described here. The taxonomy of the onchidoridid genera Adalaria and Onchidoris is discussed.
