Aphanotorulus is a genus of armored catfishes native to the Amazon, Orinoco, Essequibo and Jaguaribe basins in South America.[2][1] They typically occur on a sand or gravel bottom in slow to moderately flowing rivers and streams,[3] but some species occur in areas with fast current.[4] The largest species in the genus reaches up to 51 cm (20 in) in standard length.[3]
