背的软条 (总数) : 11; 臀鳍软条: 8. Schistura notostigma differs from all congeners from peninsular India and Sri Lanka by the
combination of the following characters: 6-7 wide, brown bars on the posterior half of the body; width of interspaces equal ½-1 times the width of the bars; black bar on caudal-fin base complete, narrower than the width of the interspaces on the body; emarginate caudal fin; incomplete lateral line ending beneath the dorsal-fin base; adpressed pelvic fin surpassing the anus; 7½ branched rays on dorsal fin; pelvic-fin origin beneath first branched dorsal-fin ray; 4-8 pre-operculo-mandibular pores; and suborbital flap in males absent (Ref. 116162).
Body shape (shape guide): elongated.
Prefers to inhabit fast flowing streams with a rock or pebble substrate (Ref. 116162). Found usually browsing among pebbles in shallow, flowing water. Can ascend steep inclines and also occurs in even the highest mountain streams (Ref. 6028).
在流动的浅滩中被发现通常在小圆石之中翻掘了。 能上溯到险峻的斜坡而且也出现于甚至最高的山地溪流中。
