was recovered which showed the Diplomystidae are the earliest-branching catfish, followed by Loricarioidei and Siluroidei as sister lineages. Thus, there is currently both morphological and molecular evidence for a higher-level phylogenetic arrangement of Siluriformes in which Diplomystidae is the earliest branching catfish, sister to a clade including the Loricarioidei and Siluroidei''' suborders. Below is a list of family relationships by different authors. Lacantuniidae is included in the Sullivan scheme based on recent evidence that places it sister to Claroteidae.
