A new fossil genus and species of the family Mesosciophilidae, Huaxiasciophilites jingxiensis gen. et sp. nov. is described. The fossils of the new genus and species were collected from the Early Cretaceous Lushangfen Formation (K 4 1 1) of Jingxi basin of Beijing China. The new genus is established based on the following characters: that Sc short, not exceed the forking of R and Rs, with branches; r‐m longer than basal part of Rs; Rs very thick and undee; and radial cell very short. The phylogenetic tree of Mesosciophilidae superimposed on the geological time scale was also analyzed. The holotype is deposited in the Beijing Forestry University.
