Romero, pers.comm. 01/16); neglecta: Named after Dr. Nybelin's feeling that this divergent form of coriiceps has been overlooked (Ref. 11892).

背棘 (总数) : 3 - 7; 背的软条 (总数) : 37 - 40; 臀棘: 0; 臀鳍软条: 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.
尾鳍子截形或略圆的, 边缘微凹的当幼鱼时。 颜色更壮观的相较于其他的 nototheniids。 在胸鳍的末梢部末端上稚鱼有一个黑色的斑块。
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).
稚鱼发现于 1-10 公尺深了而且可能地有一个大洋性的习惯，成鱼在较深的水域.(参考文献 11892) 吃甲壳动物和鱼类。 (参考文献 11892) 一些信息需要在从 N. coriiceps 到这种 (RF) 被转移。
