Neopleustes boecki (Hansen, 1887) — Stebbing 1906: 312.— Gurjanova 1951: 645, fig. 441.— Margulis 1963: 164.— Kudrjashov 1968: 94.— Barnard & Karaman, 1991: 649.— Hendrycks & Bousfield 2004: 94, 100.— Dzhurinskyi 2013: 135.
Distribution: Known from the Arctic Ocean, from the coast of Norway, Greenland and the East Siberian Sea from a depth of 9–113 m (Gurjanova 1951; Hansen 1887; Sars 1895; Stebbing 1906). Recorded from the coastal waters and shelf of Sea of Japan and Sea of Okhotsk in depth range of 9–55 m on pebbles, sand and shells (Dzhurinskyi 2013; Margulis 1963).
Remarks. Probably individuals from the lists of Margulis (1963) and Dzhurinskyi (2013) belong to the new subspecies Neopleustes boecki pacifica ssp. nov. (see below).
