臀鳍软条: 13 - 16; 脊椎骨: 43 - 44. Distinguished from other species of Rhamdia by the combination of the following characters: reduced body pigmentation; eyes rudimentary, covered by skin and not visible externally; head length 24.6-27.1% SL; pectoral-fin length 14.4-17.5% SL; maxillary barbel length 39.2-47.3% SL; caudal-peduncle depth 9.3-12.2% SL; pectoral spine serrated on posterior edge only, anterior edge smooth (Ref. 52912).
Body shape (shape guide): elongated.
与其他种的 Rhamdia 区分了藉由下列特征的组合: 缩小的身体颜色了; 眼不发达的, 被皮肤盖着了而不是看得见的外部地; 头长 24.6-27.1% SL; 胸鳍长度 14.4-17.5% SL; 上颌骨触须长度 39.2-47.3% SL; 尾柄深度 9.3-12.2% SL; 胸棘在后缘上锯齿状的了只有, 前缘平滑的.(参考文献 52912)
