Maturity: Lm ? range ? - ? cm
Max length : 8.2 cm SL 雄鱼/尚未辨别雌雄; (Ref. 37826)
背的软条 (总数) : 11; 臀鳍软条: 8. Distinguished from other species of the genus by the combination of the following characters: lateral length of head 19-22% SL (23-25% in B. mysorensis), caudal peduncle 1.9-2.8 times longer than deep (3.0-4.2 times in B. burmanica and B. brucei). Distinguished from B. annamitica by its color pattern consisting of somewhat irregular blotches on the back (versus circular in B. annamitica) (Ref. 37826). With 9-10 unbranched pectoral-fin rays (Ref. 12693).
与其他种的本属区分了藉由下列特徵的组合: 侧面的头长 19-22% SL(在 B. mysorensis 中的 23-25%), 尾柄深地 (3.0-4.2个倍 B. burmanica 与 B. brucei) 的 1.9-2.8 倍.(3.0-4.2 倍 B. burmanica 与 B. brucei) 在背部 (对圆形的在 B. annamitica 中) 上用它的包含略微不规则的斑块彩色斑纹与 B. annamitica 区分了。 (参考文献 37826) 与 9-10个不分枝的胸鳍鳍条.(参考文献 12693)
