背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀棘: 1; 臀鰭軟條: 5; 脊椎骨: 28. Can be distinguished from all its congeners by the following putative autapomorphies: unique, distinct color pattern consisting of vertically elongated blotches spanning from the dorsal midline to the ventral border of flanks; complete lateral line, without the gap plates (midbody plates without lateral line perforations) present in other Otocinclus. Can also be differentiated by having high number of teeth (30-45 in premaxilla and 23-36 in dentary). Differs from Otocinclus huaorani, Otocinclus mura and Otocinclus bororo by having a small metapterygoid channel and one W-shaped mark in the caudal fin (Ref. 57860).
能在想像的 autapomorphies 之後被與它所有的同類區分藉由: 垂直地被包含的獨特又明顯的彩色斑紋延長了從背部中線到側面的腹邊緣跨越的斑塊; 側線完整, 沒有間隙碟 (沒有側線穿孔的身體中央碟) 出現在其他的 Otocinclus. 也能被藉由區別有高的牙齒數目。 (30-45 在前頜骨與 23-36 在齒骨) 在尾鰭中藉由有一個有別於 Otocinclus huaorani ， Otocinclus mura 與 Otocinclus bororo 小的 metapterygoid 峽道與一個 W 形的標誌。 (參考文獻 57860)
