Etymology: Neobythites: Greek, neos = new + Greek, bythitis, -idos = it is at the bottom, sunken (Ref. 45335); unicolor: From the lack of color markings (Ref. 40522).

Morphology | Morphometrics
soft rays: 82 - 86. Ocelli and vertical and horizontal stripes on fins and body absent. Hind margin of preoperculum with 1 spine. Pseudobranchial filaments 2-3. Teeth granular. Ventral fin rays almost reaching anus, 17-22% SL (Ref. 40522).
Common species (Ref. 34024) found to feed on crustaceans (Ref. 32505). A specimen was caught in a glass sponge Margaritella coeloptyloides at 361 m depth off Cuba (Ref. 32505). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
