簡短描述

脊椎骨: 34. The presence of 3 bold concentric bands on posterior part of pectoral fin differentiates this species from all other Sewellia species. Combination of characters unique to the species includes: cavity with deep post-oral skinfold around mouth; absence of dark stripes on body; origin of pelvic fin in front of the origin of dorsal fin; origin of pectoral fin behind corner of mouth; pelvic fin reaching origin of anal fin; branched pelvic-fin rays 8-16 with a row of individual serrae; absence of skin-fold between oropectoral membrane and ventral surface of head; 55 scales on lateral line (Ref. 40433).
那有在胸鰭的較後面的部分上的 3條顯著的同中心的條紋區別來自所有的其他 Sewellia 種的這種。 組合特徵此魚種唯一的包括: 洞嘴的周圍有深的後口部的 skinfold; 缺乏身體上有深色斑紋; 在背鰭起點之前的腹鰭的起源; 在嘴角後面的胸鰭起點; 腹鰭達到臀鰭起點; 分枝的腹鰭鰭條 8-16 有一列個別的鋸齒; 缺乏皮膚-在 oropectoral 薄膜與頭部的腹面之間摺疊; 在側線上的 55個鱗片.(參考文獻 40433)
