簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 2 - 3; 臀鰭軟條: 54 - 61; 脊椎骨: 48 - 50. Distinct, irregularly-shaped, patch of dark pigmentation on each caudal-fin lobe which contrasts with the dark transverse bar extending from the upper anterodorsal margin of the dorsal lobe of the caudal fin to the posterior margin of the middle rays of the dorsal lobe; lack of a distinct patch of dark pigmentation on the ventral lobe of the caudal fin. Nuptial males have highly developed dorsal spine with well developed basal and distal anterior projections, modifications.
