* Eumicrotremus lindbergi (Soldatov, 1930) .

Lindberg’s Lumpsucker. To 7.4 cm (2.9 in) TL. Sea of Japan off Korean Peninsula to Sea of Okhotsk and western Bering Sea (Mecklenburg et al. 2002); one possible record from the Aleutian Islands south of the Islands of Four Mountains, Alaska (Catherine W. Mecklenburg, unpubl. data). Depth: 37–143 m (121–469 ft) (Panchenko et al. 2016). Panchenko et al. (2016) list a minimum depth of 20 m (66 ft) but without attribution. Perhaps a synonym of Eumicrotremus asperrimus (Hatano et al. 2015, Kai et al. 2015); this form is known only from males (Voskoboinikova et al. 2020). Also known as Cyclopteropsis lindbergi Soldatov, 1930 . We follow Oku et al. (2017) in recognizing Cyclopteropsis as a junior synonym of Eumicrotremus .
