Etymology: Notothenia: Greek, 'notos', ou; νοτος, ου), from the south + Greek, 'e 'eutheneia',as or 'euthenia', as (ευθενεια, ας; ευθενια, ας), 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).

簡単な記述
検索表 | 形態学 | 形態計測学
背面の脊椎 (合計) : 3 - 7; 背鰭 (合計) : 37 - 40; 肛門の骨: 0; 臀鰭: 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.
Body shape (shape guide): fusiform / normal.
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).
