Eastern Indian Ocean: Christmas Island Northwest Pacific: Marcus Island (Minami Tori Shima). These isolated populations are probably relicts of a once widespread species.
東印度洋: 聖誕島西北太平洋: 馬克斯島 (Minami Tori Shima). 這些孤立的族群可能是曾經廣泛分佈的魚種殘餘倖存者。

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 12; 背的軟條 (總數): 15-17; 臀棘 2; 臀鰭軟條: 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).
頭部與身體的鱗片細櫛狀的, 很少的圓形可能是位於頭部的腹面之上與在吻上。 藍灰色-灰色到深灰色顏色有暗淡的灰色鱗片邊緣, 呈現成列的狹窄橫紋。 身體最後面部份,尾柄, 尾鰭與背鰭的較後面的部分是鮮黃色的; 眶下的藍色而淡紫色的。 一個細長的黑色斑點有狹窄的藍色邊緣在第一與第 4個背棘之間。 胸鰭半透明的有一個黃色的紅暈。 一種小的黑色斑點在胸鰭的最上面的鰭條的基底。

生物學特性     字彙 (例如 epibenthic)

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).
