|Etymology||Greek, aphanes = hidden + Latin, torulus, -i = muscle, little string.|
|Size||400mm or 15.7" SL. Find near, nearer or same sized spp.|
|Identification||Some authors place this genus in Hypostomus despite the fact that, 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.
An elongate species that appears widespread throughout the Amazon and correspondingly has acquired a series of L numbers. We are talking about a very widely distributed, variable species. In terms of distribution and regional variation this species is to the Loricariidae what Corydoras aeneus is to the Callichthyidae. Can be most readily distinguished by its long crescent shaped caudal fin which has a red or orange outer margin.
|Sexing||Males in breeding condition posses extremely elongate, bristle-like odontodes. These cover the entire back and sides behind the dorsal fin.|
