Myzopsetta proboscidea (Gilbert, 1896) .

Longhead Dab. To 41 cm (16.1 in) TL (Andriashev 1954). Hokkaido, Japan (Nakabo in Nakabo 2002), and Sea of Okhotsk (Sakamoto in Masuda et al. 1984), to western Chukchi Sea (Mecklenburg et al. 2007), to Bathurst Inlet, south of Dease Inlet (68°20’N, 107°41’W), Nunavut (Mecklenburg et al. 2011), to eastern Bering Sea north of Unimak Island (Mecklenburg et al. 2002). A possible Queen Maud Gulf, Canadian Arctic record (Coad and Reist 2004) appears to be in error (Alfonso in Coad and Reist 2018). Benthic; marine and brackish waters (Dyldin and Orlov 2017); depth: 0–125 m (410 ft) (min.: Federov et al. 2003; max.: Allen and Smith 1988) or perhaps to 160 m (525 ft), but without documentation (Mecklenburg et al. 2016). Previously Limanda proboscidea Gilbert, 1896 (and so considered in Dyldin and Orlov 2017, Alfonso in Coad and Reist 2018, and Forster et al. 2020), we follow Mecklenburg and Steinke (2015), and Vinnikov et al. (2018), and place this species in the genus Myzopsetta .
