Phylogeny of the Amphiliidae (Teleostei : Siluriformes)

The freshwater African catfish family Amphiliidae had been reviewed based o n the 73 osteological characters with Diplomystidae, dagger Hypsidoridae, A mblycipitidae, Sisoridae, and Bagridae as out-groups. Because the family po sition of Leptoglanis (Bagridae/Amphiliidae) is under debate, this genus ha s been taken as an out-group too. Results of the study indicate that: 1) th e Amphiliidae is not a monophyletic group and must now be restricted to the genera Amphilius and Paramphilius; the two subfamilies Amphiliinae and Dou meinae are separated by the sisorids Euchiloglanis (with most of the glypto sternid fishes) and Glyptothorax (with most of the non-glyptosternid fishes ); 2) no synapomorphies were found for the subfamily Amphiliinae. 3) The fi ve genera of subfamily Doumeinae constitute a monophyletic group, Andersoni a being the sister-group of the four other genera; subfamily Doumeinae + Le ptoglanis form the family Doumeidae. The glyptosternids no longer belong to the Sisoridae (family restricted to the non-glyptosternids) and represent the new family Glyptosternidae.
