簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 24; 臀鰭軟條: 39; 脊椎骨: 68. Two terminal bulbs separated by an interspace, 1.2-2.4 times the length of distal bulb. Barbel length mostly 31-71% SL in specimens less than 8 cm; 67-91% SL in larger ones. Terminal filaments short, 4-6 without prominent bulblets, arising together from distal bulb or from a short distal stem; 1 filament thicker and longer than others. Pigment in filament axes variably present or absent. Distal bulb spheroidal to ovoid, not much longer than wide, 1.5-4.3 times proximal-bulb length. Axis of stem usually lightly pigmented, between bulbs unpigmented or lightly pigmented; dark spot present or not 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 8, sometimes 9 (Ref. 11333).
被一個間隙分開的二個末端的球莖,1.2-2.4 倍於末稍球莖的長度。 觸鬚長度大部份在標本的 31-71% SL 少於 8 公分; 在較大的一些中的 67-91% SL。 末端的絲狀突起短,4-6 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它。 在絲狀突起軸的有顏色易變存在或者不存在。 末稍球莖類似球體的對卵形體, 不是遠長過寬的,1.5-4.3 倍近端-球莖長度。 莖的軸通常顏色很淡, 在球莖之間沒有顏色或顏色很淡; 深色的斑點在末稍球莖的近側端呈現。 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 8 之間的背面中央的成對斑點, 有時 9.(參考文獻 11333)
