背棘 (总数) : 8; 背的软条 (总数) : 10; 臀棘: 7; 臀鳍软条: 9; 脊椎骨: 23. Diagnosis: Pectoral rays 17-18. Scale rows above the lateral line 20-23. Gill rakers 6-7 + 17-18. Body depth 2.35-2.4 in SL; head length 4.1-4.4 in SL; snout length 2.4-2.6 in HL; longest dorsal spine 2.05-2.1 in HL. Dorsal profile of head from above front of eye to tip of recumbent dorsal spine concave. Caudal fin deeply emarginate, caudal concavity 1.35 in HL. The head and body light blue in life, with many small pale yellowish spots and very irregular narrow yellow bands, resulting in a fine reticular pattern for most of head and body (Ref. 55950).
鉴别: 胸鳍鳍条 17-18. 在侧线 20-23 上面的鳞片列. 鳃耙 6-7+17-18. 体高 2.35-2.4 分之一标准体长; 头长 4.1-4.4 分之一标准体长; 吻的长度 2.4-2.6个 HL比率; 长的背棘 2.05-2.1个 HL比率。 头部的背面轮廓对靠着背棘的顶端的从上方眼睛前面凹曲。 尾鳍边缘深凹又尾部的凹洼 1.35个 HL比率。 头部与身体浅蓝色活着时, 有许多小的灰白淡黄色的斑点与非常不规则的狭窄黄色的条纹, 为大部分的头部与身体造成一个细的网状图案.(参考文獻 55950)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00650 - 0.03213), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (21 of 100).
