簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 25; 臀鰭軟條: 38; 脊椎骨: 67. Two terminal bulbs separated by a long interspace, 1.3-2.5 times the length of distal bulb. Barbel length 43-50% SL. Four long filaments, arising together from distal end of distal bulb or from a short stem; all with numerous conspicuous bulblets of variable size. Distal bulb 0.9-1.6 times length of proximal-bulb. Axis of stem lightly, often sporadically pigmented; axis between bulbs and in filament lightly or unpigmented. Suggestion of spot at base of distal bulb in one specimen. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 (Ref. 11333).
被一個長間隙分開的二個末端的球莖,1.3-2.5 倍於末稍球莖的長度。 觸鬚長度 43-50% SL。 四個長的絲狀突起, 一起從末稍球莖的末梢部末端出現或從矮莖; 全部有很多的可變大小的顯著球莖。 末稍球莖 0.9-1.6 的長度近端的-球莖。 莖的軸輕輕的, 時常偶而有顏色; 軸在球莖之間與在絲狀突起輕輕的或沒有顏色。 在末稍球莖的基底在一件標本的斑點的建議。 外部的鋸齒形或圓的有條紋的區域沒有顏色。 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.(參考文獻 11333)
