Abstract:Archisargidae exhibit the high diversity from the Mesozoic of China. Herein, two new Sharasargus species, Sharasargus longivenus Wang, Feng et Wang, sp. nov. and Sharasargus daohugouensis Wang, Feng et Wang, sp. nov., are described from the Mid- Jurassic strata of Daohugou, Ningcheng, Inner Mongolia. The new species show the distinct apomorphic characters that are easily distinguished from other Sharasargus species, i.e. the typically long Rs and bM1+2 in S. longivenus sp. nov., and the long R5 in S. daohugouensis sp. nov. Additionally, a key to the species of Sharasargus was provided.
