Rhamdia jequitinhonha is diagnosed from its congeners by a unique set of character states: pectoral fin spine with serrations on both sides; head sensory canals multiple; few caudal fin upper lobe procurrent rays (10); adipose fin 34.7% of SL or 141% of HL; free post-Weberian vertebrae, 39; maxillary barbels 39.2% of SL or 159% of HL; caudal fin lower lobe slightly the longer; color pattern uniform with faint lateral stripe, no apparent irregular blotches, or dark saddle-like marking across nape.
Rhamdia jequitinhonha 从它的同类被一独特组特徵描述鉴定: 胸鳍棘用锯齿在两边上; 头部感觉管倍数; 很少的尾鳍上叶前流的鳍条;(10) 脂鳍 34.7% 的 SL 或 141% 的 HL; 分离在 Weberian 之后的脊椎骨,39; 上颌骨触须 39.2% 的 SL 或 159% 的 HL; 尾鳍下叶些微地比较长; 彩色斑纹均匀的有模糊的侧面斑纹 , 没有明显的不规则的斑块 , 或像黑色鞍状斑块一样的越过后颈印记。
