Currently, the best published information on the Loricariinae can be found in Burgess (1989), but Rapp Py-Daniel's (1997) dissertation is an excellent resource.



Loricariinae can be separated from all but some hypoptopomatines based on the derived presence of a greatly dorso-ventrally flattened caudal peduncle that is rectangular in cross-section.  Loricariinae can be separated from Hypoptopomatines by lacking exposure of the pectoral girdle mesial to the coracoid strut.
