Nannobrachium fernae (Wisner, 1971).

A record of 4,939 m (16,200 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. Considered Lampanyctus fernae (Wisner, 1971) in Fricke et al. (2020).
