簡短描述
檢索表 | 型態特徵 | 形態測量圖
Two terminal bulbs separated by a long interspace, 0.6-1.8 times the length of distal bulb. Barbel length 76-92% SL. Short filaments 5-9 (less than 6% 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 long about twice as long as wide, with almost straight, parallel margins,1.5-2.5 times proximal-bulb length. Axis of stem and between bulbs with or without pigment; a black spot at proximal end of distal bulb in those with pigment. External chevron-shaped or roundish striated areas on stem unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8 (Ref. 11333).
被一個長間隙分開的二個末端的球莖,0.6-1.8 倍於末稍球莖的長度。 觸鬚長度 76-92% SL。 沒有突出的球莖的短絲狀突起 5-9(少於 6% SL), 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。 末稍球莖長的大約廣闊地兩倍長於, 幾乎直的, 平行的邊緣,1.5-2.5 倍近端-球莖長度。 莖的軸而且在球莖之間具有或者沒有有顏色; 在末稍球莖的近側端的一個黑色的斑點在那些用有顏色。 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.(參考文獻 11333)
