簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 26; 臀棘: 0; 臀鰭軟條: 40; 脊椎骨: 67. Two terminal bulbs separated by a short interspace, shorter than length of distal bulb. Barbel 68% SL. Terminal filament long (20%), with a series of 5 long branches beginning a short distance (a distal bulb length) from bulb, all with small bulblets, none of which approaches the diameter of the filament. All branches with 1 or more short branches. Stem axis peppered with melanophores; lightly pigmented on axis between bulbs and in proximal part of filament. Number of middorsal paired spots under skin uncertain (obscure and diffuse in holotype) (Ref. 11333).
被一個短分開的二個末端的球莖的間隔, 末稍球莖的短於長度。 觸鬚 68% SL。 末端的絲狀突起長的 (20%), 有一系列的開始來自球莖的短的距離 (末稍球莖長度),全部有小的球莖的 5個長的分支, 沒有那一個接近絲狀突起的直徑。 所有的分支 1 或更多短的分支。 莖軸佈滿了黑色素細胞; 顏色很淡軸之上在球莖之間與在絲狀突起的近端部份中。 在皮膚下面的背面中央成對的斑點的數字不確定的 (使與陰暗擴散的在 holotype 中).(參考文獻 11333)
