簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 7; 脊椎骨: 29. Distinguished by the color pattern with a dark blotch beneath adipose fin not extending to anal fin and by the high number of anal fin proximal radials, 12, shaped as rod-like thin tubes, the last one bearing a laminar extension. Can be diagnosed by the following combination of characters: a pectoral fin spine with a bony point and bearing proportionally few serrations on posterior border of pectoral fin spine, eight to ten; seven pleural ribs and a proportionally short head width (67.8-74.3% in HL).
區別的特徵為顏色圖案在不被延伸至臀鰭的脂鰭之下具有一個黑色斑塊與藉由高數字臀鰭近端的動脈, 12, 狀似生長著 laminar 延長的竿狀的細管，最後的。 能在組合特徵之後被鑑定藉由: 一根胸鰭棘具有一個多骨的點而且在胸鰭棘的後緣上生長著比例少數鋸齒, 八到十; 七根胸膜的肋骨與比例短的頭部寬度 (67.8-74.3% HL比率).
描述: 背鰭鰭條 i,6; 臀鰭棘條 ii-iii,7-9; 胸鰭鰭條 i,5; 而且腹鰭鰭條 i,5.(參考文獻 57827)
