簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 67 - 77; 臀鰭軟條: 51 - 57; 脊椎骨: 39 - 41. This species is distinguished by the following characters: Vertebrae 11 + 28-30 = 39-41, dorsal fin rays 67-77, anal fin rays 51-57, outer pseudoclasper with a single, long supporter, extruding into spine-like tip; inner pseudoclasper is slender with a long, straight supporter, almost length of supporter of outer pseudoclasper with ligamentous connection to outer pseudoclasper
anteriorly; penis tapering; opercular spine with single sharp tip; scale patch on cheeks with 6-9 vertical scale rows; otolith length: height ratio 2.2-2.3 (Ref. 57883).
這種被藉著下列的特徵區別: 脊椎骨 11+28-30=39-41 ，背鰭鰭條 67-77 ，臀鰭棘條 51-57, 外部的 pseudoclasper 具有一個單個，長的支持者, 進入像棘一樣的頂端之內的擠製; 內部的 pseudoclasper 是細長的具有一個長又直的支持者, 幾乎外部 pseudoclasper 的支持者的長度用 ligamentous 和外部的 pseudoclasper 的關聯
前面地; 陽物尖端細的; 鰓蓋棘有單一個銳利的頂端; 鱗片小區塊頰部有 6-9 垂直的鱗片列之上; 耳石長度: 高度比 2.2-2.3.(參考文獻 57883)
Habitat not known; no ripe females were observed (Ref. 57883).
