Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.
One of, if not the, most common of the upper Amazonian Corydoras sp. This species is common throughout the main river channel and several smaller tributaries in the Ecuadorian, Peruvian, and Colombian Amazon. It can also be found as far downriver as Tabatinga, Brazil. Most commercial collection takes place in Peru and at Leticia, Colombia.
