王俊卿   

Abstract: A new species of the Arthrodira, Livosteus sinensis sp. nov., is described from the Jiucheng Formation (Emsian, Lower Devonian) of Wuding, Yunnan. Livosteus was originally found in Latvia. Its discovery in the Jiucheng Formation represents the second occurrence of the genus in the world, and provides a basis for comparing continental formations and for studying paleogeography, since these two localities arc far away from each other.
