簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 11; 臀鰭軟條: 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).
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).
在流動的淺灘中被發現通常在小圓石之中翻掘了。 能上溯到險峻的斜坡而且也出現於甚至最高的山地溪流中。
