|Size||170mm or 6.7" SL. Find near, nearer or same sized spp.|
|Identification||Isorineloricaria 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).|
|Sexing||Mature males will develop odontodal growths on the leading pectoral fin rays and the lower caudal fin ray and peduncle.|
|General Remarks||Aqualog L093 and L195 matches DATZ L093. L195 in DATZ is a picture of an adult fish. Aqualog also shows this fish as L192, but the DATZ L192 is, most likely, as species of Hypostomus.|
