背棘 (總數) : 1; 背的軟條 (總數) : 6; 臀鰭軟條: 12 - 13; 脊椎骨: 42 - 43. Can be differentiated from its congeners in the combination of following characters: skin heavily keratinized, cranium and interneural covered with numerous large, elongate tubercles, supraoccipital and interneural without sharp ridges, skin above neural spines anterior and posterior to adipose fin never forming distinct ridges, slender elongate neural spines, elliptical eyes, body depth at anus 11.0-12.3 %SL, head width 20.3-21.7 %SL, snout length 51.4-54.7 %HL, eye diameter 4.1-8.1 %HL; 12-13 pectoral-fin rays; caudal fin with 8-9 rays; 23-24 preanal vertebrae; adipose fin with short base and angular dorsal margin; dark yellow on dorsal and lateral surfaces of head and body, fading to light yellow on ventral region; dorsal surfaces of head and body with three darkly pigmented (brown) bands or blotches; a few small brown spots irregularly distributed throughout lighter parts of body; light yellow fins with a variable pattern of small brown spots distributed irregularly, orange fins in life (Ref. 37037). Adipose origin in front or above anal fin origin; longitudinal diameter of eye 12-24 times in HL (Ref. 43281).
能在下列特徵的組合被與它的同類區別: 皮膚很重地 keratinized, 頭蓋與背側間的被覆蓋著很多的大又細長的小瘤, 上枕骨與背側間的沒有銳利的脊，皮膚上方髓棘前面與後面的對脂鰭從不在肛門 11.0-12.3% SL ，頭部寬度 20.3-21.7% SL ，吻的長度 51.4-54.7% HL 形成明顯的脊，細長的細長髓棘，橢圓形眼體高, 眼直徑 4.1-8.1% HL; 12-13個胸鰭鰭條; 尾鰭有 8-9個鰭條; 23-24個肛門前的脊椎骨; 用短的基底與有角的上緣脂鰭; 被褪成的頭部與身體的深色黃色背部與側面表面淡黃色的在腹的區域上; 頭部背面與身體有三暗有顏色 (褐色) 條紋或斑塊了; 一些小的褐色斑點在身體的顏色淡部份各處不規則地分佈了; 淡黃色的鰭有不規則地被分佈的一個小褐色斑點的可變圖案，活著時的橘色鰭.(參考文獻 37037) 前面或上方臀鰭起源的脂肪的起源; 眼 12- 的縱向直徑 24個 HL比率.(參考文獻 43281)
