This species is distinguished by the following characters: 8 head spines strong - nasal, preocular, supraocular, postocular, tympanic, coronal, parietal and nuchal spines; 2 or more infraorbital spines; differs from S. melanostictus by having a pale body with no distinct spots on the membranes of the spinous dorsal fin; shorter dorsal-fin spine 1, 1.5?3.0 times into orbit length, 4.3?7.2% SL (vs. 1.0?1.8 times into orbit length and 5.9?9.6% SL); shorter dorsal-fin spine 4, 9.8?15.5% SL (vs. 12.0?18.4% SL); shorter and fewer gill rakers, 3.4?6.3% SL (vs. 3.9?7.1% SL) and 29?34 (vs. 30?36), respectively (Ref. 87139).
头部棘强的 - 鼻骨， preocular, 眶上的，眶后的，和鼓皮似的,冠, 腔壁与颈背的棘呈现; 在眼窝的边缘上的 2 到 10(很少地 0 或 1)个棘眼睛下面.(参考文献 27437) 尾部的一般切割成锯齿状.(参考文献 6885) 色彩可变又淡红的背景有暗淡的斑块与斑点;(特别地在小的标本中) 鳍可能有黑边。 (参考文献 27437)
