簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 25 - 26; 臀鰭軟條: 37 - 38; 脊椎骨: 68. Barbel with two terminal bulbs, distal one bearing tuft of filaments (Ref. 37473); separated by a long interspace, 1.7-3.8 times the length of distal bulb in specimens larger than 7 cm SL. Barbel length 31-82% SL except when developing. Terminal filaments short, 3-7 (less than 10% SL) without prominent bulblets, arising together from distal bulb or from a short distal stem; 1 filament thicker and longer than the rest. Some or all filaments with pigmented axes. Distal bulb ovoid , only slightly longer than wide, 1.2-2.5 times proximal-bulb length. Axis of stem and between bulbs variably pigmented; a black spot or cap almost always formed at proximal end of distal bulb. External chevron-shaped or roundish striated areas on stem unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 7 or 8, sometimes 9 (Ref. 11333).
觸鬚有兩個末端的球莖, 末梢部的生長著絲狀突起的簇;(參考文獻 37473) 藉著一個長間隙分開,1.7-3.8 在標本大於 7 公分 SL 中倍於末稍球莖的長度。 除了當發展以外的觸鬚長度 31-82% SL。 末端的絲狀突起短,3-7(少於 10% SL) 沒有突出的球莖, 一起從末稍球莖或短的末梢部的莖出現; 1個絲狀突起比較厚而長度超過其他部分。 用著色的軸一些或所有的絲狀突起。 末稍球莖卵形體 , 只些微地長度超過寬的,1.2-2.5 倍近端-球莖長度。 莖的軸而且在球莖之間易變地有顏色; 一個黑色的斑點或無邊帽幾乎總是在末稍球莖的近側端形成了。 在莖上的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 7 或 8 之間的背面中央的成對斑點, 有時 9.(參考文獻 11333)
