簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 24; 臀鰭軟條: 38; 脊椎骨: 68. Two terminal bulbs separated by an interspace, 1.4-3.6 times the length of distal bulb. Barbel length mostly 36-65% SL. Terminal filaments 7-10, arising together from distal bulb or from a short stem; all prominent bulblets of various sizes and with side branches distally; 1 filament a little thicker than others and usually forked. Pigment in filament axes variably present or absent. Distal bulb small, ovoid, usually with an abruptly narrowed distal end, 1.5- 3 times proximal-bulb length, which is very small. Axis of stem and between bulbs usually pigmented, variably light or dark, sometimes unpigmented. A black spot almost always present at proximal end of distal bulb; usually partially capping base of bulb. External chevron-shaped or roundish striated areas on stem pigmented or not. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 7 (Ref. 11333).
被一個間隙分開的二個末端的球莖,1.4-3.6 倍於末稍球莖的長度。 觸鬚長度大部份 36-65% SL。 末端的絲狀突起 7-10, 一起從末稍球莖或矮莖出現; 各種不同大小的所有突出球莖與具有支流末梢部地; 1個絲狀突起稍微比其它更厚而且通常分岔了。 在絲狀突起軸的有顏色易變存在或者不存在。 末稍球莖小的, 卵形體,通常有一個突然地狹窄的末梢部的末端,1.5- 3 倍近端-球莖長度, 是非常小的。 莖的軸而且在球莖之間通常有顏色, 易變淡或深色的, 有時沒有顏色。 一個黑色的斑點幾乎總是出現在末稍球莖的近側端; 通常部份地加蓋於球莖的基底。 在莖上的外部的鋸齒形或圓的有條紋的區域有顏色或沒有顏色的。 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)
