Etymology: Gigantactis: Greek, 'gigas' or 'gigantos' = gigantic + Greek, 'aktis' = ray (referring to the unusually long first dorsal-fin spine that functions as a lure in this genus) (Ref. 86949); longicauda: From the Latin longus, for long, and cauda for tail, in reference to the deeply cleft caudal fin and elongate caudal fin rays (Ref. 41361).

背棘 (总数) : 0; 背的软条 (总数) : 5; 臀棘: 0; 臀鳍软条: 5. Metamorphosed females differ from all other Gigantactis congeners in having length of illicium 330% SL; escal bulb nearly spherical, with a short, truncated distal prolongation, pigmented distally, and bearing two pairs of short, spatulate appendages; stem of illicium without filaments (Ref. 41361); short dentary teeth (longest tooth 1.7% SL), arranged posteriorly in two longitudinal series; longest caudal fin rays 50% SL (Ref. 86949).
Body shape (shape guide): short and / or deep.
变态的雌性不同于所有的其他 Gigantactis 同类有诱饵 330% SL 的长度; 饵球几乎圆球状, 具有一个短,截形的末梢部的延伸,末梢部地有颜色, 而且生长着两对的短,竹片状的附肢; 没有丝状突起的诱饵的茎; 齿骨齿短 (长的牙齿 1.7% SL),在后部地在二纵向的系列中安排; 长的尾部鳍条 50% SL.(参考文献 41361)
Known only from the holotype collected in an open midwater trawl (Ref. 41361). Maximum length based on an immature female (Ref. 41361).
