背棘 (总数) : 0; 背的软条 (总数) : 0; 臀棘: 0; 臀鳍软条: 8 - 10; 脊椎骨: 38 - 40. Diagnosis: body elongate and cylindrical; tooth patches narrow; vertically based pectoral fin positioned at body mid-depth; caudal bar frequently extends a narrow band along the body mid-depth, dividing the pale interspace and joining the saddle and caudal bar; medial portion of pelvic fin dark with a well-defined pale rim; caudal saddle and bar pattern more prominent in juveniles and young, the darkened pelvic fin more apparent in larger specimens (Ref. 44050).
鉴别: 身体延长与圆筒形的; 牙齿区块狭窄的; 垂直地基础的胸鳍放置在身体在-之中深度; 尾部的横带时常延伸一个狭带状沿着身体在-之中深度, 分开灰白的间隙而且结合与尾部的横带; 腹鳍的中间部分深色且有一很清晰灰白的边缘; 尾部的鞍状斑与横带图案较突出的在稚鱼与幼鱼中, 颜色较深腹鳍更明显的在较大的标本中.(参考文献 44050)
描述: 身体延长与纺锤型; 头部些微地扁平的; 眼大的与侧面的; 颚等于; 16-18个腹部的脊椎骨; 21-23个尾部的脊椎骨; 19个尾鳍鳍条 (安排通常 ii-7-8-ii, 也 ii-6-8 ii 的與 iii-7-8-ii).(參考文獻 44050)
體色 身體與頭部強烈地 bicolor; 背面與側面深灰色的, 藉由腹部有時暗色的, 尤其在頭部的下面上, 但是總是多顏色淡的超過背面; 背面與側面有顯著的分散斑點了, 很少的大於 2-3 倍眼直徑, 在腹部上具有一些分散的小斑點; 尾部的鞍狀斑與橫帶圖案發展良好的與深色的; 鞍狀斑覆蓋大部分的側面, 但是臀鰭基底的停止短; 灰白的間隙是明亮的當幼魚時; 尾部的橫帶楔形的, 通常有一個前面的突出沿著身體在-之中時常延伸的深度位在前的而且和鞍狀斑合併, 完全地分開灰白的間隙; 鞍狀斑與橫帶的定義以大小減少, 只有微弱出現在 140 mm SL; 臀鰭暗有顏色始終了, 除了灰白的末梢部的邊緣; 尾鰭當成魚時堅硬地有顏色始終, 除了灰白的末梢部的邊緣; 在尾鰭的灰白的基部新月出現在稚魚與幼魚; 胸鰭暗色的當成魚時, 相當清澈在稚魚中; 腹鰭有一個輪廓分明的著色中間的部分, 顏色較深隨著年齡.(參考文獻 44050)
