Mustura subhashi, new species, is described from the Dikal River, a north bank tributary of the Brahmaputra drainage in Arunachal Pradesh. It is distinguished from all its congeners by having a colour pattern of 14-23 dark-greyish black to dark brown irregular bars on a greyish to pale beige body; pre-dorsal bars thin, numerous, wider than interspaces, weakly contrasted, uniting dorsally at lateral one-third or midway on flank to form thicker bars, coalescing further at lateral one-fifth and continuous on dorsum with contralateral bars; bars below dorsal fin exhibiting similar condition but slightly wider than pre-dorsal bars; post-dorsal bars thicker than anterior bars, wider than interspaces, sharply contrasted, rarely coalescing on flank; and a short bar along the caudal mid-line, rarely forming a blotch. Based on re-examination of the type specimens and additional materials, Mustura dikrongensis is confirmed as a species belonging to Mustura, and M. harkishorei is not sufficiently diagnosed from 'Nemacheilus' corica.
须唇魮，新种，产于阿鲁纳恰尔邦（印度东北的邦）的迪卡尔河（布拉马普特拉河的北岸支流）。本种与所有近缘种的区别在于体侧具有 14-23 条暗灰褐色至深褐色不规则条纹，体呈灰色至浅米色；前背斑狭窄、数量多、比间隔宽、弱对比，在侧面三分之一或中部背侧联合形成较厚的条纹，在侧面五分之一处进一步融合，并与对侧条纹在背部连续；背鳍下方的条纹具有相似的条件，但比前背斑稍宽；背后条纹比前条纹厚，比间隔宽，对比鲜明，在侧面很少融合；还有一条沿尾鳍中线的短条纹，很少形成斑。基于对模式标本和附加材料的重新检查，确认须唇魮dikrongensis 是须唇魮属的一个种，而 M. harkishorei 与 'Nemacheilus' corica 没有足够的区别。
