背棘 (总数): 12; 背的软条 (总数): 15-17; 臀棘 2; 臀鳍软条: 11 - 13. Diagnosis: Scales of head and body finely ctenoid, few cycloid may be present on ventral of head and on snout. Pale blue-gray to charcoal in color with dusky gray scale margins, appearing as series of narrow transverse bands. The posteriormost part of body, caudal peduncle, caudal fin and posterior part of dorsal fin are bright yellow; suborbital bluish and lavender. An elongate black patch with narrow blue margin is between 1st and 4th dorsal spines. The pectoral fins are translucent with a suffusion of yellow. A small black spot is at the base of the uppermost rays of the pectoral fin (Ref. 510). Body depth 1.9-2.1 in SL (Ref. 90102).
头部与身体的鳞片细栉状的, 很少的圆形可能是位于头部的腹面之上与在吻上。 蓝灰色-灰色到深灰色颜色有暗淡的灰色鳞片边缘, 呈现成列的狭窄横纹。 身体最后面部份，尾柄, 尾鳍与背鳍的较后面的部分是鲜黄色的; 眶下的蓝色而淡紫色的。 一个细长的黑色斑点有狭窄的蓝色边缘在第一与第 4个背棘之间。 胸鳍半透明的有一个黄色的红晕。 一种小的黑色斑点在胸鳍的最上面的鳍条的基底。
This occasionally schooling species inhabits shallow rock and coral reefs (Ref. 510). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
