簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 25; 臀鰭軟條: 40; 脊椎骨: 68. A single terminal bulb, its length more than twice its width, with a very short or no terminal projection. Bulb and projection combined 0.4-1.6% SL. Barbel 35-57% SL. Axis of stem moderately pigmented proximally, usually becoming lighter distally. External chevron-shaped or roundish striated areas unpigmented, becoming closely spaced distally. Spherical to ovoid inclusions present in distal half of stem, small and widely spaced proximally, becoming fairly crowded distally, difficult to discern in specimens smaller than about 9 cm SL. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 or 9 (Ref. 11333).
一個末端的球莖, 它的長度超過兩次它的寬度,具有一個非常短或沒有末端的突出。 球莖與突出聯合了 0.4-1.6% SL 。 觸鬚 35-57% SL。 莖的軸一般近端地有顏色, 通常末梢部地變成顏色淡。 外部的鋸齒形或圓的有條紋的區域沒有顏色, 變成末梢部地間隔很密的。 圓球狀的對卵形的包含出現在末梢部一半的莖, 小而空隙大的近端地, 末梢部地變成非常擁擠, 很難看的出來在比大約 9 公分 SL 小的標本中。 在後腦部與背鰭起點 8 之間的背面中央的成對斑點, 有時 7 或 9.(參考文獻 11333)
Mesopelagic (Ref. 58302).
