Etymology: Notothenia: Greek, 'notos', ou; ?????, ??), from the south + Greek, 'e 'eutheneia',as or 'euthenia', as (????????, ??; ???????, ??), abundance (P. Romero, pers.comm. 01/16); neglecta: Named after Dr. Nybelin's feeling that this divergent form of coriiceps has been overlooked (Ref. 11892).

Dorsal
spines
(total): 3 - 7;
Dorsal
soft rays
(total): 37-40;
Anal
spines: 0;
Anal
soft rays: 27 - 32. Caudal fin subtruncate or slightly rounded, emarginate in young. Coloration more spectacular compared to other nototheniids. Juveniles with a black blotch on distal end of pectoral fin.
Juveniles found in 1-10 m depth and possibly having a pelagic habit, adults in deeper water (Ref. 11892). Adults feed on crustaceans and fishes (Ref. 11892). Spawn once a year (Ref. 57661). Some information needs to be transferred from N. coriiceps to this species (RF).
Mature females may spawn for the first time from around 6-8 years of age (Ref. 71843).
