A new genus, Sacculiphora gen. nov., is described from China, with a new species, S. cultrata sp. nov. The new genus seems closely related to the genus Maculiphora Disney. It is distinguished from Maculiphora by the frontal bristle formula of 2-4-4 as opposed to 2-2-4, a strongly developed wing vein Sc, clearly fine veins and a cystiform structure on the inner surface of the male fore femur.
