背棘 (总数) : 1; 背的软条 (总数) : 6; 臀鳍软条: 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).
能在下列特徵的组合被与它的同类区别: 皮肤很重地 keratinized, 头盖与背侧间的被覆盖着很多的大又细长的小瘤, 上枕骨与背侧间的没有锐利的脊，皮肤上方髓棘前面与后面的对脂鳍从不在肛门 11.0-12.3% SL ，头部宽度 20.3-21.7% SL ，吻的长度 51.4-54.7% HL 形成明显的脊，细长的细长髓棘，椭圆形眼体高, 眼直径 4.1-8.1% HL; 12-13个胸鳍鳍条; 尾鳍有 8-9个鳍条; 23-24个肛门前的脊椎骨; 用短的基底与有角的上缘脂鳍; 被褪成的头部与身体的深色黄色背部与侧面表面淡黄色的在腹的区域上; 头部背面与身体有三暗有颜色 (褐色) 条纹或斑块了; 一些小的褐色斑点在身体的颜色淡部份各处不规则地分布了; 淡黄色的鳍有不规则地被分布的一个小褐色斑点的可变图案，活着时的橘色鳍.(参考文献 37037) 前面或上方臀鳍起源的脂肪的起源; 眼 12- 的纵向直径 24个 HL比率.(参考文献 43281)
