臀棘: 0; 臀鳍软条: 8 - 10; 脊椎骨: 38 - 40. Diagnosis: pectoral fin with sharply defined dark bar; caudal saddle and bar pattern well developed; lateral line extending to at least the level of the pelvic fin base (usually further, most commonly 45-50% SL); normally a single sensory pore between inner mental barbels (Ref. 44050).
鉴别: 胸鳍有轮廓分明的深色横带; 尾部的鞍状斑与横带图案发展良好的; 延伸至至少腹鳍基底的水平的侧线;(通常进一步的, 最通常 45-50% SL) 通常在内部的神经触须之间的一个感觉小孔.(参考文献 44050)
描述: 16-19个腹部的脊椎骨; 20-23个尾部的脊椎骨; 18个尾鳍鳍条 (安排 ii-7- 的 7- ii).(参考文献 44050)
体色 身体与头部双色的; 背面与侧面褐色, 腹部黄褐色的; 神经触须与头部的下面颜色较深; 背面与侧面有显著的分散斑点了,一些与一些眼直径一样大; 胸鰭鰭條深褐色的從鰭的基底到大約一半它的長度; 腹鰭清澈的; 暗被有顏色的臀鰭的後半段, 有清澈的末梢部的邊緣，其餘的白色; 尾鰭暗著色的, 除了灰白的末梢部的邊緣與灰白的基部新月; 脂鰭深色的沿著它的基底 (與那相配鞍狀斑) ，它的末梢部邊緣白色; 尾部的鞍狀斑與橫帶圖案發展良好的; 尾部的橫帶楔形的, 跨越尾鰭基底與尾柄終點, 藉由進入灰白的間隙之內是突出的尖銳的前緣; 灰白的間隙明亮的在稚魚與幼魚標本中, 逐漸地進入側面底色之內顏色較深隨著年齡; 尾部的深色與寬的, 幾乎延伸到臀鰭基底當幼魚時標本; 鞍狀斑褪色隨著年齡, 很難看見在大的成魚上，雖然尾部的橫帶與尾鰭顏色甚至在大的成魚中保持顯著.(參考文獻 44050)
