Eutaeniophorus festivus (Bertelsen & Marshall, 1956) .

Festive Ribbontail. To 5.7 cm (2.2 in) TL (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California). Circumglobal; western Pacific Ocean north to Japan (Aizawa in Nakabo 2002); Oregon to Ecuador (Charter and Moser in Moser 1996). Depth: perhaps 0–200 m (656 ft) (Mundy 2005). A record of 2,887 m (9,468 ft) (Personal communication: Scripps Institution of Oceanography Fish Collection, La Jolla, California) was based on the maximum depth fished by a midwater trawl and may represent a catch shallower than the maximum depth. We note that Fricke et al. (2020) state that this species is not found in the eastern Pacific.
