海洋 礁区鱼类; 深度上下限 0 - 96 m (Ref. 57178). 热带; 32°N - 26°S, 31°E - 165°E (Ref. 55)
Indo-West Pacific: East Africa to the Solomon Islands, north to southern Japan, south to Australia. Recently recorded from Tonga (Ref. 53797). Usually referred to as Lutjanus lineolatus by previous authors.
印度-西太平洋: 东非到索罗门群岛, 北至日本南部, 南至澳洲。 最近从东加记录。 (参考文献 53797) 通常被归属于 Lutjanus lineolatus 由先前的命名者。

背棘 (总数) : 10 - 12; 背的软条 (总数) : 12; 臀棘: 3; 臀鳍软条: 8. Dorsal profile of head gently sloped. Preorbital bone very narrow, much less than eye diameter. Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Generally silvery white, with a broad yellow stripe running along the side from the eye to the caudal fin base. A series of faint narrow yellow horizontal lines is on the lower half of the body. The fins are pale yellow to whitish (Ref. 469). Body depth 2.9-3.3 in SL (Ref. 90102).
头部的背面轮廓逐渐地斜的。 眶前骨非常狭窄的, 远小于眼直径。 前鳃盖骨凹槽与疖瘤发展不良的。 鳞片列背面斜向上升在侧联机面。 通常银白色, 具有一个沿着旁的从眼睛到尾鳍基底的宽的黄色斑纹。 一系列的模糊狭窄的黄色水平线在下面一半的身体上。 鳍是白黄色的到微白色的。
Adults inhabit offshore coral reefs and trawling grounds. Trawled to depth of almost 100 m (Ref. 48635). Frequently encountered in large schools with other Lutjanus species (Ref. 9710). Feed on fishes and crustaceans (Ref. 30573).
