Type material: holotype specimen of Berryteuthis magister shevtsovi is designated as neotype for Berryteuthis septemdentatus : mature male, 162 mm dorsal mantle length ( Fig. 1); Research Vessel “ Professor Kaganovsky ”, Sea of Japan, 42 ° 30´N, 133 ° 42´E, bottom trawl at a approx. 600 m deep, May 23, 1996. Coll. by P. V. Kalchugin , deposited in the Museum of A. V. Zhirmunsky National Scientific Center of Marine Biology (Vladivostok), Far Eastern Branch of the Russian Academy of Sciences, No MIMB 32372 View Materials GoogleMaps .

Paratype: immature female, 172 mm dorsal mantle length, the same locality and date; deposited in the same collection with the holotype, No MIMB 32373 View Materials .

The transfer of Berryteuthis anonychus (Pearcy and Voss, 1963) to new genus Okutania [ Katugin, 2004] rendered Berryteuthis a monotypic genus, but we suggest that there are, indeed, two species, which are now recognized as Berryteuthis septemdentatus and B. magister . The latter one as presently understood is likely be composed of several geographical populations for which there is preliminary evidence [ Katugin, 1998, 1999, 2000; Katugin et al., 2013; Alekseev, 2020].
