Pseudoscopelus scriptus Lütken, 1892.

Luminous Swallower. To 17.2 cm (7.5 in) SL (Mecklenburg et al. 2002). Circumglobal; western Pacific Ocean north to Japan (Okamura in Okamura et al. 1985) and southern Kuril Islands (Parin et al. 1995); western Bering Sea off northeastern Kamchatka and vicinity of Commander Islands (Sheiko and Fedorov 2000); one specimen taken in “NMFS Area 670, 47°30’N to 50°30’N ” (Personal communication: University of Washington, Burke Museum of Natural History and Culture Fish Collection, Seattle, Washington, UW 153507); probably inhabits deep waters north and south of the Aleutian Islands and in the Gulf of Alaska (Mecklenburg et al. 2002). Mesopelagic and bathypelagic; depth: 200–2,100 m (656–6,890 ft) (Mecklenburg et al. 2002). A taxon with confused taxonomy. The western Pacific form Pseudoscopelus scriptus sagamianus Tanaka, 1908, has been treated as a separate species, P. sagamianus (Melo et al. 2007, Prokofiev 2009). Fricke et al. (2020) do not recognize the genus Pseudoscopelus from within our range.
