Maturity: Lm ? range ? - ? cm
Max length : 8.2 cm SL 雄魚/尚未辨別雌雄; (Ref. 37826)
背的軟條 (總數) : 11; 臀鰭軟條: 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).
與其他種的本屬區分了藉由下列特徵的組合: 側面的頭長 19-22% SL(在 B. mysorensis 中的 23-25%), 尾柄深地 (3.0-4.2個倍 B. burmanica 與 B. brucei) 的 1.9-2.8 倍.(3.0-4.2 倍 B. burmanica 與 B. brucei) 在背部 (對圓形的在 B. annamitica 中) 上用它的包含略微不規則的斑塊彩色斑紋與 B. annamitica 區分了。 (參考文獻 37826) 與 9-10個不分枝的胸鰭鰭條.(參考文獻 12693)
Inhabits high gradient streams. Feed on benthic insects, small amounts of phytoplankton and periphyton.
棲息於高落差的溪流。 捕食底棲的昆蟲，少量的浮游植物與固著生物。
