Etymology: Krusensterniella: Named after the Russian navigator explorer, Admiral I.F. Krusenstern, who led the first Russian circumnavigation (1803– 1806) and visited that part of the Sea of Okhotsk where the type species was found. Of the two Russian-language names 'krusensterniella' (Taranets, 1937) and 'kruzenshternia' (Sheiko and Fedorov, 2000)—the first one has come into scientific use (Ref. 130195); pseudomaculata: Name from Latin 'maculata' and the prefix 'pseudo', meaning 'false' or 'fake'.

Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 101 - 104; Radios blandos anales: 84 - 86; Vértebra: 104 - 107. This species is distinguished by the following characters: pungent spines of D2 VI-XI, starts in the middle of the length of the caudal part of the body, associated with the caudal vertebrae
22-37; all spiny rays (D1 + D2) 50-55; rays in D1 and in D3 is similar: 40-48 and 45-54; vertebrae 104-107; D 101-104 (40-48 VI-XI 45-54), A 84-86; well developed scales only on the caudal part, only single scales on the sides in front of the beginning of anal fin (Ref. 130195).
Cross section: compressed.
Collected from two captures, where the water temperature was 1.3 and 2.0°C; bottom sediments were silt, sand, pebbles, and stones (Ref. 130195).
