Etymology: Benthalbella: A possible interpretation is related to Greek, benthos = the deep sea + Latin, albus = white; but it is need more information.

Short description
Identification keys | Morphology | Morphometrics
Oceanic, mesopelagic or bathypelagic species (Ref. 6601, 58302). Most adults have been taken in hauls to depths considerably in excess of 500 m (Ref. 10755). Adults prey on other midwater fishes (Ref. 6691).
