英文摘要	A new genus and species of tooth-plated lungfish, Sinodipterus beibei gen. et sp. nov., is described from the Qujing Formation (Middle Devonian, late Eifelian) of Zhaotong, Yunnan, China. The new form resembles Dipterus in the skull table, but differs in its tooth-plate: cosmine-like tissue absent near the midline, tooth rows fewer in number (7 to 8) and less divergent radiating, and no reparative dentine layers. Phylogenetic analysis of Devonian lungfish based on a dataset of 150 characters and 33 taxa indicates that the new taxon is more crownward than Dipterus and the clade comprising Adololopas, Sorbitorhynchus and Pillararhynchus. Our results agree broadly with previous cladistic solutions. Diabolepis is placed as a sister group to all other Devonian lungfish. The species referred to Chirodipterus fail to form a monophyletic group. The result shows a large number of convergences corresponding to early radiation of lungfish compressed in time.
