A molecular phylogeny of the north‐east Atlantic species of the genus Idotea (Isopoda) with focus on the Baltic Sea
Today, the marine isopods of the genus Idotea Fabricius, 1798 consist of 26 accepted species. Most species can be found in the Northern Hemisphere. While some species have a cosmopolitan distribution, others are endemic to a few coastlines. In the Baltic Sea, Idotea species have a key role as import...

Today, the marine isopods of the genus Idotea Fabricius, 1798 consist of 26 accepted species. Most species can be found in the Northern Hemisphere. While some species have a cosmopolitan distribution, others are endemic to a few coastlines. In the Baltic Sea, Idotea species have a key role as important meso‐grazers. Only three species can be found in this brackish environment, I. balthica , I. chelipes and I. granulosa, while nine species are described from the whole European coast. The goal of the present study was to reconstruct the phylogeny of the genus Idotea and to test whether the Baltic low‐salinity tolerant species represent a single lineage within the genus.
