简单描述
型态特徵 | 形态测量图
臀鳍软条: 10 - 11; 脊椎骨: 38 - 40. Having the following autapomorphic characters: postcleithral process expanded; suborbital tubule 3 and respective i5 branch and pore of infraorbital latero-sensory canal absent. Shares with Nemuroglanis lanceolatus the following eight apomorphies: five or six pairs of pleural ribs; dorsal caudal plate supports only six principal caudal-fin rays; ventral caudal plate much smaller than dorsal caudal plate, supporting only three or four rays; dorsal caudal-fin lobe with five or fewer branched rays; dorsal caudal-fin lobe very long, usually greater than 40% SL; ventral caudal-fin lobe usually with nine to 13 rays; ventral caudal-fin lobe with only three or four branched rays; and caudal fin lanceolate. Differ further from its congeners by possessing fewer vertebrae, 38-40 and fewer anal-fin rays, 10-11; maxillary barbel length , 38.8-55.8% SL; and anal-fin base length, 13.9-16.2% SL (Ref. 55662).
有下列的 autapomorphic 特征: postcleithral 突起扩大; 眶下骨细管 3 与分别的 i 5个分支与眶下 latero 的孔-知觉管不存在。 与 尖头线油鲶〔Nemuroglanis lanceolatus〕 下列的八 apomorphies 分享: 五或六对胸膜的肋骨; 背部的尾部碟只支撑六个主要的尾鳍鳍条; 腹的尾部碟被只有支撑三或四个鳍条的远小于背部的尾部碟; 背部尾鳍叶有五个或较少的分支条; 背部尾鳍叶非常长又通常大于 40% SL; 腹面尾鳍叶通常有九到 13個鰭條; 腹面尾鰭葉只有三或四個分支條; 而且尾鰭矛尖形的。 藉由持有較少的脊椎骨進一步不同於它的同類, 38-40 與較少的臀鰭棘條, 10-11; 上頜骨觸鬚長度 , 38.8-55.8% SL; 而且臀鰭基底長度， 13.9-16.2% SL.(參考文獻 55662)
