@BOOK{TreeBASE2Ref20856, author = {M. C. de Pinna}, title = {Higher-level phylogeny of siluriformes, with a new classification of the order (Teleostei, Ostariophysi).}, year = {1993}, keywords = {}, doi = {}, url = {http://}, pmid = {}, isbn = {}, publisher = {The City University of New York}, address = {New York City}, editor = {}, abstract = {The higher-level phylogeny of siluriform fishes, focusing on family-level relationships, is studied on the basis of 239 morphological characters, new and compiled from the literature. The 30+ currently recognized catfish families are split into 79 terminals for the analysis, in order to provide meaningful resolution of some potentially nonmonophyletic nominal families. The already well-supported monophyly of the order is further corroborated, and a total of 27 catfish synapomorphies are reviewd or newly proposed. The Diplomystidae are further supported as the sister group of all other known siluriforms, living and fossil. Main discoveries about relationships include: 1- the Cetopsidae are the sister group of Helogenidae; 2- the clade formed by Cetopsidae plus Helogenidae is the sister group of all other non-diplomystid, non-hypsidorid catfishes; 3- the malapteruridae form a monophyletic group with Auchenoglanididae (formerly subfamily Auchenoglanidinae of the Bagridae); 4- Hypthalmus (formerly in the monotypic Hypophthalmidae) is the sister group of Parapimelodus of the Pimelodinae; 5- the Pimelodinae are the sister group of a restricted group of Asian bagrids including Bagrus, Mystus, Aorichtys, and Hemibagrus; 6- the Chacidae, Clariidae, and Plotosidae form a monophyletic group; 7- the Heteropneustidae are the sister group of a subset of current Clariidae, and should be included in the latter family; 8- the Ariidae are monophyletic, and form a clade with Pangasiidae and Schilbidae. The recently proposed monophyly of the Pimelodinae is further corroborated. The hypothesis of relationships advanced here forms the basis for a new familial and suprafamilial classification of the Siluriformes.} }
