背面の脊椎 (合計) : 2; 背鰭 (合計) : 7; 肛門の骨: 1; 臀鰭: 5; 脊つい: 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).
Facultative air-breathing in the genus (Ref. 126274); Found in a medium size creek with clear water and lost of marginal vegetation (Ref. 57860).
