Distribution and remarks:

Doris pseudoargus is widely distributed along the Norwegian coast from the Swedish border in the south to the Russian border in the north ( Evertsen & Bakken 2005). While reported in Russian waters for the first time as late as 2000 ( Redkin & Martynov 2001) D. pseudoargus is now considered a common species there. In Tromsø, animals were frequently observed all year round. Observations were made both in the intertidal and at fouling communities where animals were mainly found associated with the sponge Halichondria panicea Pallas, 1766 . Spawning was observed at all seasons. Together with other recent records from northern Norway ( Artskart 2024) the findings of the present study demonstrate that D. pseudoargus has a well-established presence in the Tromsø region.
