Maturity: Lm ? range ? - ? cm
Max length : 25.8 cm SL 雄魚/尚未辨別雌雄; (Ref. 38209); 最大體重: 74.70 g (Ref. 125977)
背棘 (總數) : 0; 背的軟條 (總數) : 10 - 11; 臀棘: 0; 臀鰭軟條: 9 - 11; 脊椎骨: 48 - 49. The location of the dorsal-fin base largely posterior of the vertical through the anal fin origin distinguishes this species from all congeners except B. maculata, from which it differs in possessing a narrow, dark, horizontal stripe extending from the rear of the orbit of the caudal peduncle, the presence of distinct, dark cross-bars on the lobes of the caudal fin, and absence of dark spots about the size of the pupil on the body.
背鰭基底的地點主要地後面垂直的經過臀鰭起源除了 B. maculata 以外將此種與所有的同類區分開, 從它不同之處為持有延伸尾梗的眼窩從後面的一條狹窄的﹐深色的﹐和水平的斑紋, 那有在尾鰭的葉上的明顯又深色的交叉條紋, 而且缺乏深色的斑點大小大約等於在身體上的瞳孔。
