Eumicrotremus gyrinops (Garman, 1892) .

Alaskan Lumpsucker. To at least 9.2 cm (3.6 in) SL ( Stevenson et al. 2017). Paramushir Island, Russia ( Voskoboinikova 2019b) and at least west-central, central, and eastern Bering Sea (in vicinity of Saint Paul Island) and throughout Aleutian Islands to off Kodiak Island ( Stevenson et al. 2017). Depth: 59–329 m (193–1,079 ft) (min.: Stevenson et al. 2017; max: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California as Lethotremus muticus ). We follow Stevenson et al. (2017) and consider Eumicrotremus muticus ( Lethotremus muticus ) (Garman, 1892) and Eumicrotremus phrynoides Gilbert & Burke, 1912 to be junior synonyms. However, we note that Voskoboinikova (2019a) retains the species status of both of these taxa. In addition to species now recognized as its junior synonyms, Eumicrotremus gyrinops has often been misidentified as Eumicrotremus asperrimus (Tanaka, 1912) or E. birulai Popov, 1928 . However, these two species, if they are both valid, are part of the Western Pacific clade of the E. asperrimus complex ( Kai et al., 2015), and their distributions appear to be restricted to the western Pacific, Sea of Okhotsk, and Sea of Japan.
