Maturity: Lm ? range ? - ? cm
Max length : 25.8 cm SL 雄鱼/尚未辨别雌雄; (Ref. 38209); 最大体重: 74.70 g (Ref. 125977)
背棘 (总数): 0; 背的软条 (总数): 10-11; 臀棘 0; 臀鳍软条: 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.
背鳍基底的地点主要地后面垂直的经过臀鳍起源除了 B. maculata 以外将此种与所有的同类区分开, 从它不同之处为持有延伸尾梗的眼窝从后面的一条狭窄的，深色的，和水平的斑纹, 那有在尾鳍的叶上的明显又深色的交叉条纹, 而且缺乏深色的斑点大小大约等于在身体上的瞳孔。
