Some species in the Arctic and Baltic Astarte–complexes have been described or redescribed. From the Arctic A. borealis–complex: A. borealis (Schumacher, 1817), A. jenseni n. sp., A. nuuki n. sp., A. moerchi n. sp., A. sericea Posselt 1895. From the Arctic A. elliptica–complex: A. elliptica (Brown, 1827), A. neocrassa n. sp., A. longa n. sp., A. vaigati n. sp. In the Baltic Sea the former “A. borealis”–complex has been substituted by 6 species: A. bornholmi n. sp., A. silki n. sp., A. belti n. sp., A. fjordi n. sp., A. falsteri n. sp., A. nordi n. sp. Part of the Baltic A. elliptica / A. sulcata–complex is studied: A. elliptica (Brown, 1827), A. anholti n. sp., A. klinti n. sp. and A. sulcata (da Costa 1778). A few notes on the A. mon-tagui–complex and the A. crenata–complex have been added.
