背的软条 (总数) : 25; 臀鳍软条: 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).
被一个短间隙分开的二个末端的球茎,0.4-1.6 倍于末稍球茎的长度。 触须长度短 37-44% SL 在超过 8 cm SL 的标本中。 三到 9个短, 通常 bulblet 顶端的丝状突起与 2个长的一些, 一起从末稍球茎的末梢部末端出现或从矮茎。 长的丝状突起在标本大于 8 公分中变成 23-35% SL; 1个长的丝状突起具有一个突出的大 bulblet 。 末稍球茎 1.2-2.5 的长度近端的-球茎。 有颜色得好的茎的轴; 在球茎之间易变地有颜色, 有时在末稍球茎的近侧端形成一个深色的斑点或小的无边帽。 外部的锯齿形或圆的有条纹的区域通常没有颜色。 在后脑部与背鳍起点 8 之间的背面中央的成对斑点.(参考文献 11333)
