摘　　要：Lower brachyceran flies are abundant in the Late Mesozoic of China.Many extant and extinct members of that have been found in Inner Mongolia,Liaoning,Hebei and Shandong provinces. A new family,Origoasilidae fam.nov.,belonging to the lower Brachycera,is built based on a new specimen from the Yixian Formation and is a representative of the Jehol Biota.The new endemic Mesozoic family possesses several unique characters in the wing.The relationship among the Origoasilidae fam.nov.and relative known lower brachyceran flies has been discussed.Lower brachyceran flies are abundant in the Late Mesozoic of China.Many extant and extinct members of that have been found in Inner Mongolia,Liaoning,Hebei and Shandong provinces.
