脊椎骨: 41 - 42. Possesses the following autapomorphies: lower jaw slightly pronounced; epiphyseal branches of supraorbital latero-sensory canals not fused to each other; preoperculomandibular and postotic latero-sensory canals separated from each other; ventral caudal plate much smaller than dorsal plate, supporting only three rays; and ventral caudal-fin lobe with only three branched rays. Shares with Nemuroglanis pauciradiatus 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 its anal-fin base length 18.4-26.4% SL; caudal peduncle length 11.3-14.5% SL; maxillary barbel length 39.8-58.6% SL; and vertebrae 41-42 (Ref. 55662).
持有下列的 autapomorphies: 下颌些微明显; 眶上 latero 的 epiphyseal 分支-感觉管不融合彼此; 鳃颚前而耳后的 latero-感觉管与彼此分开了; 腹的尾部碟被只有支撑三个鳍条的远小于背部的碟; 而且腹面尾鳍叶只有三个分支条。 与 Nemuroglanis pauciradiatus 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; 背部尾鰭葉有五個或較少的分支條; 背部尾鰭葉非常長又通常大於 40% SL; 腹面尾鰭葉通常有九到 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。 用它的臀鰭基底長度 18.4-26.4% SL 進一步不同於它的同類; 尾柄長度 11.3-14.5% SL; 上頜骨觸鬚長度 39.8-58.6% SL; 而且脊椎骨 41-42.(參考文獻 55662)
