Lampanyctus tenuiformis (Brauer, 1906).

To 15.6 cm (6.1 in) SL (Parin in Fischer et al. 1995). Circumglobal (Hulley and Paxton in Carpenter and De Angelis 2016); western Pacific Ocean north to Japan (Nakabo in Nakabo 2002) and Russian north-western Pacific (Orlov and Tokranov 2019); northern California (37°06’N, 122°50’W) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California) to South America (Wisner 1976). Depth: 10–3,200 m (33–10,496 ft) (min.: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California; max.: Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). The deepest record is based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth.
