簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 69-73; 臀鰭軟條: 63 - 68; 脊椎骨: 72 - 80. Two suprabranchial pores. Teeth simple, long, slightly convex rearward. Lower lobe of the pectoral fin long, contained 3-3.5 times in SL. Pectoral fin with a large notch; upper lobe is short, and does not reach to the origin of the anal fin. The rays of the lower lobe are approximately twice as long as those of the upper, reaching origin of the anal fin.
二個鰓前孔。 齒單一的﹐長的﹐和些微中凸後方。 胸鰭的下葉長的, 包含了 3-3.5 標準體長比率。 胸鰭有一個大的凹槽; 上葉是短, 而且不會到臀鰭起點。 下面葉的鰭條是大約兩倍長於被達到臀鰭起點的上面者的。
