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

Taxonomy

The taxonomy of this genus has been a matter of dispute, all having been placed in Hypostomus in the past, and some occasionally placed in Squaliforma. Squaliforma is now regarded as a synonym of Aphanotorulus, but species west of the Andes have been moved to Isorineloricaria.

There are currently 7 recognized species of Aphanotorulus:

Of these species, the validity of A. phrixosoma is questionable, as the only known specimen likely is a hybrid between A. horridus and A. unicolor.
