论文摘要 A new genus and species of tooth-plated lungfishes, Dianodipterus huizeensis gen. et sp. nov., is described from the Qujing Formation (late Eifelian, Middle Devonian) of Huize County, Qujing, north-eastern Yunnan, China. It differs from other lungfishes in the small proportion of the tooth-bearing part on the pterygoid (less than one-quarter), the extensively developed anteromedial edentulous portion of the pterygoid, and tooth rows few in number (only four). Phylogenetic analysis reveals that Dianodipterus is more plesiomorphic than Dipterus, yet crownward of Melanognathus. As the ninth Devonian lungfish genus from China, the new taxon displays a novel schema of lungfish dentition and increases the diversity of early lungfishes.
