簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 25; 臀鰭軟條: 38; 脊椎骨: 68. Two terminal bulbs separated by a short interspace, 0.4-1.6 times the length of distal bulb. Barbel length short 37-44% SL in specimens over 8 cm SL. Three to 9 short, usually bulblet-tipped filaments and 2 long ones, arising together from distal end of distal bulb or from a short stem. Longest filament becoming 23-35% SL in specimens larger than 8 cm; 1 long filament with a prominent large bulblet. Distal bulb 1.2-2.5 times length of proximal-bulb. Axis of stem well pigmented; between bulbs variably pigmented, sometimes forming a dark spot or small cap at proximal end of distal bulb. External chevron-shaped or roundish striated areas usually unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8 (Ref. 11333).
被一個短間隙分開的二個末端的球莖,0.4-1.6 倍於末稍球莖的長度。 觸鬚長度短 37-44% SL 在超過 8 cm SL 的標本中。 三到 9個短, 通常 bulblet 頂端的絲狀突起與 2個長的一些, 一起從末稍球莖的末梢部末端出現或從矮莖。 長的絲狀突起在標本大於 8 公分中變成 23-35% SL; 1個長的絲狀突起具有一個突出的大 bulblet 。 末稍球莖 1.2-2.5 的長度近端的-球莖。 有顏色得好的莖的軸; 在球莖之間易變地有顏色, 有時在末稍球莖的近側端形成一個深色的斑點或小的無邊帽。 外部的鋸齒形或圓的有條紋的區域通常沒有顏色。 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)
