Sisoroidea is a superfamily of catfishes (order Siluriformes). It contains the four families Amblycipitidae, Akysidae, Sisoridae, and Erethistidae; many sources also include Aspredinidae. With Aspredinidae, this superfamily includes about 42 genera and 230 species.{{cite book|title=Fishes of the World|last=Nelson|first=Joseph S.|publisher=John Wiley & Sons, Inc|year=2006|isbn=0-471-25031-7}}
Taxonomy
Sisoroidea is sister to the Loricarioidea. The monophyly of this superfamily is supported by a number of morphological characters. Amblycipitidae is the most basal family and is sister to the remaining families. Based on morphological data, Erethistidae is the sister group to Aspredinidae, with Sisoridae being the sister group of the clade formed by these two families.{{cite journal|first=R.|last=Diogo|author2=Chardon, M. |author3=Vandewalle, P. |year=2003|title=Osteology and myology of the cephalic region and pectoral girdle of Erethistes pusillus, comparison with other erethistids, and comments on the synapomorphies and phylogenetic relationships of the Erethistidae (Teleostei: Siluriformes)|journal=Journal of Fish Biology|volume=63|issue=5|pages=1160–1175|doi=10.1046/j.1095-8649.2003.00235.x}} However, it has been proposed to move the erethistid genera back into Sisoridae.{{cite journal|url=http://silurus.acnatsci.org/ACSI/library/biblios/2007_Ferraris_Catfish_Checklist.pdf|title=Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types|first=Carl J.

Distribution
Sisoroidea includes almost exclusively Asiatic catfish families with the exception of Aspredinidae, which is native to South America.{{cite journal|url=http://digitallibrary.amnh.org/dspace/bitstream/2246/2802/1/N3437.pdf|title=The Second Ural Centrum in Siluriformes and Its Implication for the Monophyly of Superfamily Sisoroidea (Teleostei, Ostariophysi)|first=Mário C.
