背的軟條 (總數) : 78 - 86; 臀鰭軟條: 63 - 69; 脊椎骨: 44 - 46. This species is characterized by the following: Vertebrae 11-12+33-35=44-46, dorsal fin rays 78-86, anal fin rays 63-69; eyes large (2.0-3.1% SL), D/V 6; outer pseudoclasper large, broad, wing-shaped, with concave inner face; inner pseudoclasper joined to outer pseudoclasper anteriorly, thin, with narrow base and single-pointed tip extending over anterior part of outer pseudoclasper; moderately broad scale patch on cheek with 5-8 scale rows, large scale patch on operculum above opercular spine (13-21 scales) and separated smaller scale patch below opercular spine (3-7 scales); head is massive and thick (Ref. 57884).
這種特徵為那在:之後 Vertebrae 11-12+33-35=44-46 ，背鰭鰭條 78-86, 臀鰭棘條 63-69; 眼大的 (2.0-3.1% SL), D/V 6; 外部的 pseudoclasper 大的﹐寬的, 翼-形狀的, 有凹的內面; 內部的 pseudoclasper 前面地連到了外部的 pseudoclasper, 細的, 有狹窄的延伸超過外部 pseudoclasper 的前部的基底與單個-尖的頂端; 一般寬的鱗片小區塊頰部有 5-8 鱗片列之上, 大規模的小區塊在上面鰓蓋棘 (13-21個鱗片) 的鰓蓋上而且在鰓蓋棘 (3-7個鱗片) 之下分開較小的鱗片小區塊; 頭部是大而厚的。 (參考文獻 57884)
