背棘 (總數) : 9; 背的軟條 (總數) : 10; 臀棘: 3; 臀鰭軟條: 8; 脊椎骨: 23. This species is distinguished by the following characters: Dorsal rays IX, 10; anal rays III, 8; pectoral rays 13; lateral-line interrupted, with pored scales to caudal-fin base 15 + 6; gill rakers 5-6 + 8-9; body moderately elongate, depth 3.1-3.55 in SL; head length 2.45-2.55 in SL; snout long and pointed, 2.6-2.8 in head; dorsal profile of snout straight or with a slight concavity of snout to above eye; lower jaw is slightly projecting; maxilla reaching or nearly reaching a vertical at anterior margin of orbit; caudal fin of females slightly rounded, the upper 3 principal rays slightly prolonged; fin of males rhomboid with the upper 3 rays more strongly projecting; pectoral fins 2.6-2.95 in head; body and fins pale yellowish when preserved, with a blackish posterior margin on caudal fin, broader and black in male; first interspinous membrane of dorsal fin dusky; red in life on about upper half of body with 5 irregular pale bars, pale red on lower half with 3 pale stripes containing small white spots; posterior edge of caudal fin blackish to black (Ref. 56651).
這種被藉著下列的特徵區別: 背鰭鰭條 9,10; 臀鰭鰭條 3,8; 胸鰭鰭條 13; 側線中斷, 藉由有細孔的鱗片到尾鰭基底 15+6; 鰓耙 5-6+8-9; 身體中等細長且縱深的 3.1-3.55 分之一標準體長; 頭長 2.45-2.55 分之一標準體長; 吻長而尖的, 2.6-2.8個頭長比率; 背面輪廓吻筆直地或具有一個對眼睛上方的吻的輕微凹窪; 下頜些微突出; 顎骨達到或者幾乎延伸到眼窩的在前緣的一條垂直線; 雌性的尾鰭略圓的, 上面的 3 主要的鰭條些微地延長; 具有上面人的雄性偏菱形的鰭 3個鰭條更強烈突出; 胸鰭 2.6-2.95 頭長比率; 身體與鰭灰白的淡黃色的在保存狀態下, 在尾鰭上具有一個黑色的後緣, 比較寬與黑色的在雄魚中; 第一個背鰭的棘間膜暗色的; 紅色的活著時在大約身體有的上半部上 5條不規則的灰白橫帶, 在下半部上的灰白的紅色有三個包含白色小斑點的灰白的斑紋; 尾鰭的後緣黑色的到黑色的.(參考文獻 56651)
