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) : 17 - 19; 臀鰭軟條: 12 - 13; 脊椎骨: 36 - 37. Distinguished from its congeners by the following characters: supraocular and parietal spines absent; nuchal spine obscure; uppermost preopercular spine unbranched; no scales between dorsal scale row and lateral line scale row, and no scales below lateral line scale row; supraocular, parietal, and nuchal cirri present; five dark brown saddles dorsolaterally; 13 anal fin rays; 15 pectoral fin rays; vertebrae 12 + 24-25 = 36-37. Male holotype with a secondary sexual character, a unique ensiform flaps on the distal tips of the first dorsal fin (Ref. 58328).
與它的同類區分了藉由跟隨特徵: 眶上與腔壁的棘不存在; 頸背的棘陰暗; 最上面的前鰓蓋骨棘不分枝的; 沒有鱗片在背部的鱗片列與側線鱗片列 , 與沒有鱗片在側線下鱗片列之間; 眶上的﹐腔壁的﹐與頸背的觸鬚呈現; 背外側地的五個深褐色的鞍狀斑; 13個臀鰭棘條; 15個胸鰭鰭條; 脊椎骨 12+24-25=36-37. 雄性 holotype 在第一背鰭的末端上具有一個第二的性特徵 , 一個獨特的劍形鰓蓋。 (參考文獻 58328)

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=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref.
