IdentificationIsorineloricaria can be distinguished from Aphanotoroulus by having caudal peduncle proportions that get proportionately longer with size and that become round in cross-section (vs. caudal peduncles that do not become greatly lengthened with size and that are oval in cross section) and by having spots almost as large as lateral plates on a nearly white background (vs. small dark spots (less than half plate diameter) on a light tan background).
