Olyra saginata, new species, is described from the Kaladan [=Kolodyne] River system in Mizoram, northeast India. It differs from congeners in having the following unique combination of characters: interorbital distance 27.9-35.9% HL; 54-66 lateral-line pores; body depth at anus 10.5-12.0% SL; length of adipose-fin base 17.3-22.4% SL; adipose fin separate from upper principal caudal-fin rays; post-adipose distance 11.8-14.3% SL; caudal peduncle length 14.8-17.7% SL; and caudal peduncle depth 7.8-8.9% SL. The taxonomy of congeners is also briefly discussed.
新物种长体鳅（Olyra saginata）是根据印度东北部米佐拉姆邦的卡莱丹[=科洛迪内]河水系描述的。它与同属物种的区别在于具有以下独特的特征组合：眶间距为头长的27.9 - 35.9%；有54 - 66个侧线孔；肛门处体高为标准体长的10.5 - 12.0%；脂鳍基部长度为标准体长的17.3 - 22.4%；脂鳍与上尾鳍主鳍条分离；脂鳍后距离为标准体长的11.8 - 14.3%；尾柄长为标准体长的14.8 - 17.7%；尾柄深为标准体长的7.8 - 8.9%。文中还简要讨论了同属物种的分类学问题。
