摘　　要：Herein the description and illustration of two new fossil genera and species of Naucoridae,Exilcrus cameriferus gen. ＆ sp. Nov. and Miroculus laticephlus gen. ＆ sp. Nov., are provided. Both species were collected from the Late Jurassic to Early Cretaceous Yixian Formation of western Liaoning, China. The complete preservation of the new specimens enable us to determine the characters of the specimens reported here. This finding represents the first record of fossil Naucoridae from China, which includes well-preserved nymphs. The possibility of a predatory habit of these specimens is discussed.Herein the description and illustration of two new fossil genera and species of Naucoridae,Exilcrus cameriferus gen. ＆ sp.
