簡短描述
檢索表 | 型態特徵 | 形態測量圖
This species is distinguished by having its pelvic fins reaching only about halfway from the pelvic-fin base to anal origin, and the second dorsal-fin insertion notably advanced with respect to the anal-fin origin; cephalic lateral-line pores large, the fourth supraorbital canal pores open into a median, well-defined, depressed interorbital pit, divided medially by a slightly raised ridge; width of depressed interorbital region greater than the length, does not extend anteriorly beyond the third supraorbital canal pore, and with a few uniserial cycloid scales immediately anterior to it; the lining of the mouth, gill cavities, and peritoneum black (Ref. 58577).
這種被藉著區別讓它的腹鰭達到對臀鰭起點的只有大約中途的從腹鰭基底, 與特別地被前進的第二個背鰭嵌入相對於臀鰭起源; 頭部的側線孔大的, 第四個眶上管孔開放的進入中動脈之內, 很清晰, 中間地被一個些微凸起脊分開的扁平的眼間骨凹洞; 扁平眼間骨區域的寬度大於長度, 不延伸到前面地超過第三個眶上管孔, 而且具有一些排成一列的圓形鱗片緊鄰它之前; 嘴巴，鰓腔與腹膜黑色的襯裡.(參考文獻 58577)
