簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 8; 臀鰭軟條: 4; 脊椎骨: 29 - 31. Can be distinguished from other species of the genus by possessing the following unique combination of characters: distinct secondary rostrum present; incomplete post-oral pouch present; pockets posterior to mouth corners; sublacrymal groove visible from side; body with plain uniform pattern when adult, with thick cream bars and blotches when juvenile, head dorsum plain; subopercular groove absent; gill slit vertical; sublacrymal groove present; a truncate snout when viewed dorsally; abdomen without scales; 55-61 scales on lateral line; pelvic fin just touching anal fin origin, adpressed dorsal fin not overlapping level of anal fin origin (Ref. 57871).
能被藉由持有下列的獨特組合特徵與其他種本屬區分: 明顯的第二喙呈現; 不完全的後口部的小袋呈現; 口袋在嘴角後面; sublacrymal 凹槽看得見的從側邊; 身體有單色的均勻圖案當成熟的時候, 有厚的乳黃色的橫帶與斑塊當稚魚 , 頭部背面單色的; 子鰓蓋凹槽不存在; 鰓縫垂直的; sublacrymal 凹槽呈現; 一個截形的吻當背面看了; 腹部沒有鱗片; 在側線上的 55-61個鱗片; 腹鰭正好碰觸臀鰭起源，不部分重疊程度的臀鰭起源的緊貼的背鰭.(參考文獻 57871)
