摘要
A new species, Drabescoides umbonata sp. nov., of the leafhopper genus Drabescoides Kwon & Lee is described and figured from China. A key separating the new species from the two other species of the genus, Drabescoides nucahlis Jacobi and Dra-bescoides undomarginata Cen & Cai, is given together with new records for the latter two species and figures of undomarginata. The type specimen of the new species is kept in the collection of the Entomological Museum, Northwest Sci-Tech University of Agriculture and Forestry (NWSUAF).
