Four new eriophyoid mite species of the genus Diptilomiopus Nalepa (Acari: Diptilomiopidae) from China are described and illustrated. They are D. cotoneastrus sp. nov. on Cotoneaster acutifolius Turcz. (Rosaceae), D. clidemioidus sp. nov. on Boehmeria clidemioides var. diffusa (Wedd.) Hand.-Mazz. (Urticaceae), D. quinatus sp. nov. on Vitex quinata (Lour.) F.N.Williams (Lamiaceae), and D. macropodus sp. nov. on Daphniphyllum macropodum Miq. (Daphniphyllaceae). All new species are distributed in the Oriental Region of China. They are vagrants on the leaves causing no apparent symptom to their host plants. We further provided mitochondrial cox1 gene sequences for the four new species.
