Squaliforma is now regarded as a synonym of Aphanotorulus, but species west of the Andes have been moved to Isorineloricaria.[2] There are currently 7 recognized species of Aphanotorulus:[2][4]
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.[2] References1. ^{{FishBase genus | genus = Aphanotorulus| month = May | year = 2017}} {{Taxonbar|from=Q4779516}}{{Loricariidae-stub}}2. ^1 2 3 4 Ray, C.K. & Armbruster, J.W.
