Identification In Aphanotorulus, all species show clear sexual dimorphism and have a generally flatter appearance than other hypostomine genera. The posterior edge of the oral disc is jagged rather than smooth. Aphanotoroulus can be distinguished from Isorineloricaria by having caudal peduncles that do not become greatly lengthened with size and that are oval in cross section (vs. caudal peduncle proportions that get proportionately longer with size and that become round in cross-section), and by having small dark spots (less than half plate diameter) on a light tan background (vs. spots almost as large as lateral plates on a nearly white background.

All Aphanotorulus show clear sexual dimorphism and have a generally flatter appearance.
Sexing Males in breeding condition posses extremely elongate, bristle-like odontodes. These cover the entire back and sides behind the dorsal fin.
