簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 9; 背的軟條 (總數) : 10; 臀棘: 3; 臀鰭軟條: 9. Males recognized by the blue snout and band behind eye. Eastern form has blue cheek and western form has yellow cheek. Females grey to yellow with dusky saddle over back (Ref. 48636). Closely resembles S. oviceps and S. scaber. In S. oviceps, the initial phase has fewer, less vertical diagonal dark bars on the back and the terminal phase lacks the light-centered bar between the eye and the pectoral fin base, is darker and less brilliant blue on the upper head and back, and is usually larger.
雄性辨識特徵為藍色的吻與條紋在後眼了。 東方形式有藍色的頰，而且西方的形式有黃色的頰。 雌性灰色的黃色有在背面上的暗色鞍狀斑.(參考文獻 48636) 非常近似 S. oviceps 與 S. scaber. 在 S. oviceps, 最初的階段有較少的, 較不垂直的斜深色的橫帶在背部上與最後階段缺乏中心淡色的橫帶在眼與胸鰭基底之間, 顏色較深而比較不色彩豔麗藍色在上面的頭部與背部上, 而且通常是比較大的。
