臀鳍软条: 13 - 15; 脊椎骨: 42 - 44. Distinguished from its congeners in having a dorsal caudal plate that supports eight principal rays; ventral caudal plate that articulates with six or seven rays; dorsal caudal-fin lobe with seven branched rays; dorsal caudal-fin lobe long, up to approximately 35% SL; ventral caudal-fin lobe with 15-19 rays; ventral caudal-fin lobe with six branched rays; forked caudal fin; and short maxillary barbels, 33.3-40.4% SL. Differs further from Nemuroglanis lanceolatus in having shorter anal-fin base, 12.4-18.1% SL; and longer caudal peduncle, 17.5-20.1% SL; and from N. pauciradiatus in having more vertebrae, 42-44 and more anal-fin rays, 13-15 (Ref. 55662).
在有一个方面与它的同类区分了支撑八个主要的鳍条的背部的尾部碟; 与六或七个鳍条连接的腹的尾部碟; 背部尾鳍叶有七个分支条; 背部尾鳍叶长的, 大约向上到 35% SL; 具有 15-19个鳍条的腹面尾鳍叶; 具有六个分支条的腹面尾鳍叶; 叉型尾; 而且短的颚触须， 33.3-40.4% SL。 进一步不同于 尖头线油鲶〔Nemuroglanis lanceolatus〕 有较短的臀鳍基底， 12.4-18.1% SL; 而且较长的尾柄, 17.5-20.1% SL; 而且从 N. pauciradiatus 有更多的脊椎骨， 42-44 與更多的臀鰭棘條, 13-15.(參考文獻 55662)
