摘　　要：我国中生代始水虻科昆虫多样性非常丰富,本文新记录了来自内蒙古宁城道虎沟中侏罗世地层莎水虻属Sharasargus下的两个新种:长脉莎水虻Sharasargus longivenus Wang,Fenget Wang,sp.nov.和道虎沟莎水虻Sharasargus daohugouensis Wang,Feng et Wang,sp.nov.。其中,长脉莎水虻具有较长的Rs和bM_(1+2)与其他种明显分开,而道虎沟莎水虻的R_5明显延长与其他种明显区分;此外,本文还编制了莎水虻属分种检索表。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.
